Wholesale Color PP Packing Tape Manufacturers This type of nut will be most common style in use, and it come in virtually all industrial, construction, and structural fastener applications.

A variety connected with hex nut sizes can be found, each with different thread pitches and materials, which is why these are used in a wide range of applications and industrial sectors. The most frequently found hex nuts are constructed with steel, with grades ANY (applicable to specifications having a thread diameter involving d16mm) and B (suitable intended for d> 16mm). They can be bought in both coarse as well as fine-tooth styles, each having unique benefits and employs.

For example, the fine-tooth hex nut has good locking performance and it is suitable for anti-vibration. On the other hand, it cannot become adjusted without getting rid of the nut and requires a bigger operating space than a coarse-thread hex enthusiast.

In addition to hex nuts, some others of DIN crazy include wing loco with rounded wings and also coupling nuts. Depending on the application, these fasteners may be specified in also DIN 934 or even ISO 4032. These fasteners are available in a variety of finishes, including plain finish, zinc plated, in addition to hot-dipped galvanized. These products are available in the FCH Sourcing Multilevel database from many fastener distributors. The DIN S / s Square Nut

The DIN Stainless steel Square Nut is a kind of nut with four-sided floors (compared to typical six-sided Hex Nuts) which naturally provide much more surface contact using the part it’s fastening, thus offer greater level of resistance to loosening. Their reduced elevation profile makes them perfect for low clearance, stretched space applications. They usually are tightened with either pliers or wrenches, and are also commonly used around blind spots for example metal channels or maybe railroad applications.

This fastener is frequently used in stormy environments for rust resistance, and it’s also a hot choice across industrial sectors including automotive, motorsport, commercial machinery, architectural end work, agriculture, foodstuff processing, clean energy plus much more. In addition to being highly economical alloy, it’s easy to help fabricate and possesses tensile strength homes that exceed lots of carbon and aluminum grades.

The main components during this alloy are chromium, dime and iron, with other elements for example manganese and carbon present in smaller quantities. The corrosion resistance that material offers is largely because of its high chromium articles, which creates some sort of barrier that puts a stop to oxygen and waters molecules from getting into the interior with the steel. This core protects the base steel from oxidation, that will be further protected that has a protective coating.

Stainless steel nuts are almost always used in conjunction with a mating bolt to hold the two components together. They are placed together by a variety of the friction of these threads, a slight stretching from the bolt, and compression with the parts being joined.

How do you calculate safety factor for lifting?

The safety factor for lifting is the ratio between force applied to a component in a system, and the minimum breaking strength of the component. The safety factor is calculated by dividing the minimum breaking strength of the gear by the maximum force that can be supported by the lifting gear.

If the safety factor is less than 1, it implies that the force exceeds strength, and the component would fail.

When it comes to the estimation of maximum force, riggers can use maximum static force or maximum dynamic force. The former refers to the force when the system is motionless, and the latest refers to the force generated when a falling load is caught.

Safety factors are calculated based on status loads. This makes it easier to calculate static forces in the field. Rescuers ensure that systems can accommodate dynamic loads using sufficiently high safety factors. For instance, a component with a static safety factor of 10:1 encounters dynamic events that generate forces five times more than expected, making the dynamic safety factor ratio 2:1.

Grip strength, sometimes overlooked, can have an effect on the safety factor of the lifting gear.

Strength of manufactured equipment is well tested and accurate - if gear is maintained and inspected on a regular basis, the strength estimates required might weaken the gear. This could include knots, sharp edges that could cut ropes or even a cross-loaded carabiner.

However, the strength of anchors connected to certain objects are difficult to estimate. These components are selected on site without testing. Anchor strength estimates must therefore be conservative.

Minimum strength estimates can be accurate if conservative estimates for anchors, rope strength adjustments for knots, use of sufficient edge protection and consideration of rope angles are made.

Maximum force is more difficult to estimate than minimum strength. It involves accurate estimation of the gear being lifted, in addition to rope angles that can increase forces. The effects of friction are also not meant to be neglected, which can increase or decrease forces, while raising or lowering.

Optimum safety factors ensure that systems are stronger than the forces encountered. An increase of safety factors beyond this does not enhance safety. An increase of safety factors of individual components beyond the system’s lowest safety factor does not contribute to lifting gear strength.

“ Dutest provides a wide range of lifting accessories and safety equipment through its rigging outlets. All types of lifting equipment including but not limited to Wire Rope Slings and Accessories, Chain Slings, Webbing Slings, Round Slings, Black Slings for the entire industry, Chain Blocks, Lever Hoists, Load Cells, Eye Bolts, Beam Clamps, Trolleys, Plate Clamps, Magnets, Safety equipment including Safety Harness, fall protection systems, lanyards, and force measuring equipment are supplied by the company “

Bolting Service that helps maintenance schedule under heavy vibrational loads

In applications involving pressure vessels and pipe flanges in the oil and gas industry for leak-free connections, as well as in automobiles and machinery for vibration protection, the reliability of bolted joints is accorded the utmost priority. The Fit-it-Forget-approach is frequently used when it comes to structural joints that must last for a long time, such as bridges and skyscrapers.

Bolt load precision has a particularly crucial function in determining joint reliability among other aspects. Understanding the notion of controlled bolting mechanism, a scientific way of bolting, is necessary to regulate the effect of external influences on bolt load, such as temperature and vibration. Here is how bolting service helps maintenance schedule under heavy vibrational loads:

Bolting Service that helps maintenance schedule under heavy vibrational loads

Ineffective bolted joints can have serious repercussions depending on your application. A single unsecured bolt has the power to shut down an entire manufacturing facility, incur financial loss for the company, and even jeopardize public safety.

There are numerous causes of bolt loosening. Speaking generally, faulty or corroded fasteners, corrosion, an unsuitable preload, poor assembly, or high vibrating loads are all potential causes of loosening of bolted joints.

Any pressure bolted joint assembly has the potential to loosen, posing a risk to safety.

An average-sized oil and gas refinery may often have up to 100,000 bolted joints, all of which carry the risk of leaking and posing a safety risk to the refinery, the environment, and even human lives.

In the immediate vicinity of the plant, some leaks do result in modest, low-risk incidents, while others may cause catastrophic loss of life and property as well as significant environmental harm.

There is a tried-and-true method for protecting Joint Integrity from these dangers. In other words, the simplest technique to maintain joint integrity for flanges is controlled bolting service.

Before you decide how to maintain the integrity of a bolted joint, take these factors into account:

Functionality of the Bolt

Check if it's possible to reuse the bolt, for instance during scheduled maintenance or a shutdown, or must a new one be purchased instead. Check the pitch to see if there are any damages from threads or galling. Calculate the bolt's elasticity (Utilize a fresh bolt if the previous one is damaged i.e., enters in the plastic region)

Safety

If safety precautions are not followed, bolt tightening processes might be harmful. Choosing an ECITB Training Approved Certified Technician will assure Joint Integrity by combining safe procedures with effective bolting procedures. A trained technician will ensure that all safety regulations are followed to the letter while maintaining the operation's effectiveness.

Cost

The expense of buying or renting fastening tools is less expensive in the long term than the cost of an impending calamity.

Not only will a fastener system stop bolts from loosening, but it will also allow for reaction arm-free operations. It is the perfect remedy for a troublesome joint. When torque is applied, the acclaimed anti-loosening mechanism improves load delivery.

Why are Controlled Bolting Services Important in Infrastructure Joints?

Multiple aspects are taken into consideration in order to ensure joint integrity. The precision of the bolt load is one of the key factors. These elements are taken into account to regulate the temperature and vibrations on the bolt load. First the science underpinning controlled bolting should be understood in order to comprehend this. After being bolted, infrastructure bolts are hardly undone. Due to the fact that this is a one-time job, the fastening tools are tightened more than other fasteners. Bolts with a grade class of 8.8, 10.9, etc. are commonly utilized in the infrastructure sector. High Strength Friction Grip bolts are also employed in specific circumstances. The assembly of the fasteners used for high strength structural bolting complies with EN 14399 criteria. A washer, nut, and bolt make up these fasteners. After the bolting services are finished, all of the bolts are preloaded with a load greater than their acting load.

Lubrication is a crucial element in calculating bolt loads using torque instruments. To prevent corrosion, these fastening tools are pre-lubricated with coatings that can endure the temperature and weather of the environment. The load created in a bolt will be specified by the manufacturer while applying torque to the bolt. The erosion of the lubricant during storage and the interval between production and bolt installation are discussed.

Final words

In conclusion, precise bolt load in the infrastructure industry depends on exact bolting. This is only achievable if the proper hardware, tool, and operator competence are chosen and developed.

The Best Manufacturer for Rollers, Cores and Shafts

Rollers are widely used components that serve the simple yet surprisingly diverse functions of facilitating and processing material and product movements in manufacturing and/or industrial settings. While standard rollers are rollers actually touching the material, there are also conveyor rollers available that are employed in conveyor applications. No matter the industrial application, there is probably a roller system that is a perfect fit. The primary differentiator between rollers is the roller material at the point of contact with the material or product because this dictates the function, geometry, and available features of the rollers.

Live Shaft Rollers: engineering Roller design is typically steel journals/headers welded into the ends of a hollow tube or roller body. The journals (or shaft) turn with the roller body. The roller is considered to be a “live shaft” because the journal ends rotate with the roller. Commonly mounted to a customer’s machine or frame through the use of external bearings such as pillow block bearings. Roller shells can be steel, aluminum, or carbon fiber and can be lightweight thin-walled rollers, but also – and more typically – are heavy steel-walled rollers for high-load industrial applications. Commonly used in steel, paper, and other industries requiring strong robust roller designs and often use heavy-duty pillow block bearings for mounting on the journals. Rollers can be driven via keyways machined into the journals, therefore, allowing for the use of various drive systems to turn rollers. please go here R2R Engineering to get more live information about Manufacturers for Rollers, Cores, and Shafts

Metallic rollers: These rollers are explicitly designed for sustaining heavy component movement because they can carry a large bearing load with a medium touch. Metallic rollers, the workforce of rollers, are employed to move higher loads where workpieces can tolerate a bit of a rough handling touch. These rollers are available in straight or crowned geometry across a wide range of sizes with bearing, set screw, or mounting methods.

Urethane/Rubber rollers: In general these types of rollers are found in applications that necessitate large contact and holding friction forces. They’re also found in more delicate operations such as processing/smoothing wrinkles in paper and/or plastic films. These kinds of rollers are employed where pieces cannot sustain damage on the surface or the part as a whole. Similarly, rubber rollers are employed in material processing applications where a light material is required, such as paper, textile, or sheet metal manufacturing or processing. In this fashion, they are even employed in the sheet metal industry where low gauge sheet metal is coiled up into large rolls and the surface finish integrity of the sheet metal is vitally important. These rollers can be specified with a variety of hardware choices, such as Bearings, set screws, bushing, bolts, keyways or shafts. They are also available in straight or crowned geometry with grooved or knurled heard to add friction and increase the grip strength of the roller system.

Rubber rollers are used for a variety of purposes and are found in many manufacturing processes. The basic uses for rubber rollers are found in the manufacturing processes of textiles, film, sheets, paper, and coiled metal. Rubber-covered rollers are used in all sorts of container and packaging fabricating equipment as well as machinery used for the sanding and grinding of wood, steel, and aluminum. Industrial rubber rollers or rolls are used in applications that require a high degree of contact and holding friction, and also in material processing applications requiring a soft touch. Rollers are usually in the shape of cylindrical or spherical shapes and are devices that roll or rotate, like for example, a small spoke-less wheel or a roller skate or caster. Rollers are also used in printing. For printing purposes, it is a hard rubber roller that is used to ink the type before the paper is impressed. Rubber rollers are also the ideal choice for peripheral decorating of cylindrical shapes and roll-on decorating of large flat or curved surfaces. Covered rolls are used extensively in the graphic arts industry.

Resin Rollers: Resin rollers are similar in function to rubber/urethane rollers, but resin rollers are actually metallic core base rollers that have undergone a surface application of resin coating. These rollers are used in applications similar to urethane or rubber rollers, for applications that require a soft touch or instances where ink or resin coatings are to be applied. Outside of industrial material movement applications, they are also typically used in the industry for packaging and/or polymer material storage applications. These rollers are only available in straight shape but can be specified with bearings or side-mounted bolt hardware.

Nuts Bolts and their importance

New products and technology are introduced as time passes to better human society. Bolt is one such product utilized worldwide and has been one of the most valuable products in the industrial revolution.

Nut bolt is one of the few tools that are still used in essentially the same shape as they were previously, and there isn't a place or field where they aren't employed in large quantities, whether at home, in machinery, or in automobiles. Contact Expodar, one of the leading nut bolt manufacturers to know more.

What caused the change?

Old items are being modified to make them more effective and workable in today's challenging climate, while new inventions are being introduced.

Updated versions of products are sweeping the market, from the tiniest items to the most complicated, not because they are novel but because they are more productive, generally less expensive, and more efficient than their predecessors.

What makes them superior?

High-strength friction grip nut bolts are superior to their counterparts because they can endure more fatigue and have a higher tensile strength, allowing them to be used in more flexible environments. Furthermore, they have greater power carrying capacities and are less prone to loosen and fall because of their superior construction. They also have a higher load-bearing capacity than standard bolts, making them more likely to be employed. High-strength friction grip nut bolts are utilized to construct huge buildings and structures. They're also used in steel projects and machinery that require a lot of flexibility. Most rotating pieces of machinery make use of them because they don't loosen up readily.

Shape and design

High-strength friction grip bolts are usually made of iron and steel, and they include grooves on their surfaces that cause friction. Furthermore, they come with nuts that secure the bolt's tip and prevent it from slipping. These bolts are one of the most valuable items and a magnificent example of engineering genius. Contact Expodar, one of the leading nut bolt manufacturers to know more.

How does a bolt appear?

Let's start with a straightforward definition. Bolts are threaded fasteners having male threads on the outside. They mate with nuts that have female or internal threads.

What is the purpose of nuts?

The bolt and the nut create a bolted joint by gripping the secured materials and limiting axial movement. The bolt joint's action is due to the nut's axial clamping force and the bolt's shank, which functions as a rod that presses the joint against sideways shear stresses. This is why threadless bolt shanks are so standard - they make for a stronger rod.

Bolts V/S screws

The distinction between bolts and screws is commonly considered the equipment used to install each — a wrench for bolts and a screwdriver for screws. However, this isn't always the case. Bolts can feature screw-like heads and require a screwdriver to install.

Types of Bolts

Hexagonal-headed bolt

The most popular type of bolt is used for general fastening. The upper end of the hexagonal head is chamfered. Another spanner retains the bolt-head to prevent bolt rotation when screwing the nut on or off.

Square-Headed Bolt

This bolt is usually utilized when the head fits into a recess. The square form of this recess prevents the bolt from spinning when the nut is tightened on or off. When a square-headed bolt is used with its head projecting outside, it is equipped with a square-section neck. This prevents the bolt from rotating. This bolt is typically seen in shaft bearings.

Cylindrical or Cheese-Headed Bolt

When protruding corners are not acceptable, and room for placing the bolt-head is limited, this bolt style is employed. A pin put into the shank just below the head prevents the bolt from rotating. The projecting section of the pin fits into a similar groove in the surrounding component. This bolt is often used with large ends, eccentrics, and other similar applications.

Cup-Headed or Round-Headed Bolt

This bolt is employed when unwanted projecting and a better appearance is required. A sign is usually forged on the shank directly below the head. To keep the bolt from rotating. This bolt is utilized in the building of tanks and some locomotive components.

T-Head bolts

Clamps, vices, and other accessories are secured to machine tool tables with this bolt type. T-slots are supplied on the tables to allow T-heads.

Star washers include either internal or external tabs, allowing them to be used in a broader range of applications. In contrast, outer tabs run along the outside diameter, giving superior locking capabilities and making them excellent for applications requiring constant reliability.

Know about stainless steel dowel pins

A stainless steel dowel pins manufacturer cuts the cylindrical rods dowels into a shorter length known as a pin, often fashioned from wood, metal, or plastic. Externally threaded dowel pins are commonly employed in a variety of other applications as structural reinforcements.

There are no moving or actuating components in Grade 303 Stainless Steel Dowel Pins. The stainless steel lock nut can help you to increase the strength of your alloy. The properties of the Stainless Steel Extractable Dowel Pins are derived from the high coefficient of friction. You can also use other adhesives if you want to increase the strength.

Know about the stiffness of the stainless steel dowel pins.

The Stainless Steel Threaded Dowel Pins' stiffness allows them to keep assembled parts aligned without needing metal attaching later. You should also know about Astm a453 grade 660 as they are also solid. For a secure fit, the hole you make for them should be either the same size as the hole you made for them or slightly smaller.

The Stainless Steel Imperial Dowel Pins and grade 8 hex bolts could be used as movable game pieces or pegs; furniture shelf supports or wheel axles in toys, hooks for apparel, keyrings, tools, etc. detents in gymnastics grips. Slotted, tapered, or grooved Grade 316 Stainless Steel Dowel Pins are available.

What are Grade 660 ASTM A453 alloys?

THE SPECIFICATION OF the ASTM f593 bolts is for studs, bolts, nuts, and other fasteners used in high-temperature bolting operations. The ASTM A453 Grade 660 is divided into four property classes each having its own set of tensile and stress rupture qualities. The 12.9 Grade Allen Bolt is excellent for installing in tight locations where standard wrenches are ineffective.

Grade 660 fasteners are utilized in the bolting of high-temperature boilers, pressure tanks, pipeline flanges, and valves. ASTM A453 Grade 660 stainless steel alloys, also known as alloy A286 and UNS S66286, are chemically identical to ASTM B638 grade 660 stainless steel alloys, heat-treated to attain qualities stated in ASTM A453 specification. The material is corrosion-resistant and can withstand temperatures of up to 889 degrees Celsius due to the combination.

Properties of ASTM A36

ASTM A36 bolts specify structural carbon steel forms' chemical and mechanical properties and offer general structural applications. ASTM A36 is hot-rolled and mild steel robust, flexible, and easily machinable, making it one of the most popular steel forms in widespread use.

Q1) Can hex bolts be used in applications involving vibration?

Ans) Yes, hex bolts can be employed in situations where vibration is a concern. However, there are several important factors to consider in order to maintain the stability and reliability of the connection. Vibration can lead to the loosening of bolts over time, which may result in component failure or disassembly. Here are some strategies for effectively using hex bolts in applications prone to vibration:

1. Precise Torquing: During installation, ensure that the hex bolts are torqued to the recommended specifications. Insufficient torque can cause bolts to loosen due to vibration, while excessive torque can result in thread stripping or bolt stress.

2. Locking Mechanisms: Employ locking mechanisms to prevent hex bolts from coming loose. These mechanisms create friction or interlocking features that resist movement caused by vibration. Examples include nylon insert lock nuts, serrated flange nuts, and prevailing torque nuts.

3. Threadlocker: Apply threadlocker compounds to the bolt threads before installation. Threadlocker adhesives establish a bond that prevents loosening due to vibration. Different strengths of threadlocker are available, so choose the one suitable for your specific application.

4. Spring Washers: Consider using spring washers (Belleville washers) beneath the bolt head or nut. These washers flatten and release energy, providing constant tension that counters the effects of vibration-induced loosening.

5. Nyloc Nuts: Nyloc nuts, also called nylon insert lock nuts, feature a nylon collar that tightly grips the bolt threads. This prevents the nut from backing off due to vibration.

6. Serrated Flange Nuts: Serrated flange nuts incorporate a serrated flange that grips the surface and resists rotational movement brought about by vibration.

7. Safety Wire: In environments with high levels of vibration, safety wire can be used to physically secure hex bolts. This involves threading wire through the bolt heads or nuts to prevent loosening.

8. Regular Inspections: Conduct periodic inspections of the hex bolts and their connections to identify signs of loosening or movement. Address any issues promptly to prevent further complications.

9. Consider Alternatives: In extremely vibration-prone environments, contemplate using specialized fasteners engineered to withstand such conditions. Examples include self-locking fasteners and adhesive fasteners.

When employing hex bolts in situations involving vibration, it's vital to evaluate the specific demands of the application, the magnitude of the vibration, and the potential repercussions of loosening. By selecting appropriate locking mechanisms and adhering to proper installation practices, hex bolts can be effectively utilized in environments susceptible to vibration, all while upholding the integrity of the fastened components.

Threaded Rod – Everything You Need To Know

What is threaded rod?

Threaded rod, often referred to as a stud, is a rod of varying length that is threaded in a helical structure.

Similar in appearance to a screw, the threading extends around and along the rod to cause rotational movements when in use. Threaded rods combine linear and rotational movement to create strong resistance to pressure.

The direction of the rotation caused by a full threaded rod depends on whether the rod has a right-hand thread, left-hand thread, or both.

Designed to withstand very high levels of pressure and tension, threaded rods are a common fixing for support systems and used for a variety of applications.

What is a threaded rod used for?

Threaded rods are fasteners and functions thanks to the threading, which causes a tightening action from the rotational movement. Threading on a rod allows other fixings like bolts and nuts to easily screw or fasten to it.

Threaded rods have many applications, effectively working as a pin to fasten or connect two materials together.

Also used to stabilize structures, they can be inserted into various materials like concrete, wood or metal to either temporarily create a steady base during construction or they can be installed permanently.

How to choose the correct threaded rod

There are several types of threaded rod available on the market that will suit different purposes, conditions and materials.

The fully threaded rod that Armafix supplies are usually used when effective grip strength is required through the entire length of the rod.

They are often used to align structures or are embedded into materials, like concrete, as the threading provides good resistance.

The material is another essential factor to consider when choosing the best-suited rod for your application.

Threaded rods are used in a variety of sectors and for several purposes such as construction, plumbing, manufacturing, marine, agricultural, oil extraction and contractor work.

How to cut threaded rod

Sometimes threaded rod will have to be cut to suit your project. It is a common question and not quite as simple as you might think. The rod can be difficult to hold in place and the threading can be affected.

Perhaps the easiest and more efficient way of cutting threaded rod is to use a rod cutter, which will produce a clean, burr-free cut with less effort and less time wasted, plus it is lightweight and can be used for overhead work.

Cutting threaded rod with a hacksaw

If you’re using a hacksaw, a good tip is to take a small block of wood and drill a hole through it to place your rod through.

Secure the rod in the vice with two nuts either side using a thin kerf, the rod can then be cut and held in place. Once it is cut, you can unscrew the nuts, which will tidy up the ends and keep the threading in good shape.

A simple illustration of this can be found here.

Another efficient method is to use a bench vice to hold the rod in place, and an angle grinder to cut the rod. Cut the road at a flat angle and be sure to wait a few minutes before touching the newly cut edge after using an angle grinder as it will be hot.

How to bend threaded rod

As well as cutting threaded rod, sometimes it needs to be bent in order to fit the intended application. This involves using a mounted bench vice and propane or Oxy-Acetylene torch and should be done with caution.

Placing two bolts in the vice again to clamp around the rod, fix the threaded rod securely in place. Apply the lighted torch on the part of the rod you wish to bend.

Metal can be damaged by too much heat, but for stainless steel – as a general rule of thumb – once it is a reddish colour, it is ready to bend. You can reheat the rod several times until you have the required shape.

Remember to use heavy-duty gloves and eye goggles!

How to join threaded rod

If you need to connect threaded rods, you can use connector bolts to get the required length and secure them together.

You can also use threaded rod plastic protection caps to cover and protect the ends.

The welded washers are usually there for shear (tension wouldn't require the weld EDIT: IT WOULD REQUIRE THE WASHER, THOUGH). If you have adequate friction resistance or shear keys under the baseplate, you don't need welded washers. If you designed the connection to resist lateral loads through shear in the bolts, it depends. If you designed for 2 of the 6 bolts (I'm guessing at your layout) to take all of the shears, you probably don't need the welded washers as long as your ok with movement of the base of the column equal to the diameter of the oversized hole (again, assuming it's oversized) minus the anchor diameter (Not half, but all - what if the anchor is slightly off and hard against the opposite side of the hole? There's a reason oversized holes are used in baseplates.) If you need all of the bolts to resist the shear, then you need to have welded washers at all of the bolts. If you don't, you could have a couple bolts closer to the sides of the holes than others, so they'll load first and prevent the others from loading until they have deflected and/or failed - and then the others engage with two fewer than needed and the rest fail.

We Rebuild a Junkyard Transmission to Hold Nearly 1,000 hp

Cheap turbo + junkyard LS = big power. The formula has been proven multiple times. However, significant power won’t last long with a junkyard transmission. Thanks to the aftermarket, there are several cheap alternatives to an all-out drag transmission. We rebuilt a junkyard 4L80E to handle 1,000 hp—for $1,000.

The plan was simple: Take a 2003 4L80E and rebuild it, upgrading the common failure points. Parts include a McLeod performance rebuild master kit (PN# 88075K, $618.75); Bowler Transmissions 300M hardened input shaft (PN# TCS HP-4L80E-35, $310); and Sonnax Smart-Tech overrun clutch valve kit (PN# 34200-40K, $118.53). We spent $1,047.28, not including transmission and labor.

OEM Rating

Traditional automatic transmissions, such as the TH350, TH400, and 700R4, generally max out at less than 400 lb-ft. GM strengthened them through their respective generations. In 1982, the TH350 gained a Fourth gear and became the 700R4. In 1990, it became the 4L60E, which incorporated updated technology that improved strength. The same applied to the TH400 which, with the addition of an Overdrive gear, became the 4L80E in 1991. The 4L80E evolved to include more upgrades, including a stronger Overdrive sprag and hardened input shaft around 1997. The even stronger 4L85E, introduced in 2002, is rated for vehicles as heavy as 16,500 pounds.

Today, if you’re building an LS drivetrain with an OEM computer or trans controller, it’s likely backed by a 4L60E or 4L80E. The 4L60E is far more abundant in the junkyard and therefore cheaper. A local transmission shop will rebuild a 4L60E for around $900 to $1,200 and a 4L80E for $1,300 to $1,800, with used units going for about $400 and $600 to $1,000, respectively.

Many forums will tell you the numbers in the name refer to torque rating, but that’s only partially true. The “6” and “8” refer to the torque capacity based on Gross Vehicle Weight (GVW), so the 4L60E is rated to handle a 6,000-pound GVW, and the 4L80E 8,000 pounds. That’ll help when finding the right donor vehicle.

The 4L60E is rated to hold 360 lb-ft, and the 4L80E is good for 440 lb-ft engine torque and up to 885 lb-ft of output torque. Bowler Transmissions believes that an accurate torque rating of a 4L80E’s internals, on a prepped track with grip, is around 550 lb-ft, but that’s with a Sonnax Smart-Tech overrun clutch valve kit. Companies that manufacture drivetrain components (such as transmissions, rear-end housings, and lockers) are often dodgy about setting firm torque-capacity ratings, as many factors contribute to breakage. “We pride ourselves on providing ratings based on a tire hooking up. That’s the biggest determination,” said Mark Bowler, owner of Bowler Transmissions. “An 800hp car with 8-inch-wide street tires, that’s never going to break anything.”

The Components

The McLeod performance kit is suitable for 1,000 lb-ft, and McLeod claims this is the only kit of its kind, a complete master kit with name-brand gaskets and performance discs. The package includes OEM-quality National Oil seals, Farpak gaskets, Teflon-coated rings that produce a tighter seal, and a brass filter that makes for better flow and filtration.

We opted for the upgraded Kolene steel clutch discs for their added performance; it retails for $618.75. The same kit with standard steel replacement discs retails for $493.75.

Kolene is a treatment applied to the steel clutch packs that increases holding capacity as much as 10 percent. “But more importantly, it helps prevent warping in high-stress and high-heat applications,” said Brian Gwin, of McLeod Racing Domestic Sales.

Both kits include Stage 1 Raybestos friction pads, which McLeod says have greater holding capacity, improved durability, and less wear than other red performance plates on the market. “The higher coefficient of friction is ideal for high-output engines,” said Gwin. The plates are simple drop-ins, and they’re the most significant performance improvement in the kit. The clutches will produce a smoother engagement, cut down on operating temperatures, and enhance shift feel.

The Bowler Transmissions 300M hardened shaft is good for 1,000 ft-lb and is included in all of Bowler’s performance transmissions (Stage 2 and up). Finally, the Sonnax Smart-Tech overrun clutch valve kit engages the overrun clutch at all times except in Overdrive (4th gear), reducing the chance of an Overdrive-sprag failure.

Our Build

Our 4L80E came from a friend who couldn’t guarantee its condition. We picked it up for less than core charge at $200. We visited local hot rod builder John Young of Winston-Salem, North Carolina, with our parts in hand.

The McLeod kit includes an intermediate-reverse band, but not a low-reverse band. Whether or not this is a common replacement item is debatable. Ours was peeling, a possible result from accidently washing it. We sourced a remanufactured band from a local transmission shop for $35.

Monster Transmissions also offers a rebuild kit that consists of more hard parts, such as solenoids, a shift improver kit, a manifold switch, a harness, and sprags. It retails for around $880 to $1,050, depending on the size of kit and year range.

Today, there are tons of options in the aftermarket to bump up power ratings on drivetrain components. Here’s the quick rundown of our rebuild.

Brand Item Part Number Price Sonnax Smart-Tech Overrun Clutch Valve Kit PN# 34200-40K Price: $118.53 McLeod Performance Automatic Transmission Rebuild Kit PN# 88075K Price: $618.75 Bowler Transmissions 300M Hardened Input Shaft PN# TCS HP-4L80E-35 Price: $310 Total $1047.28

The 4L80E came from a 2001 Chevrolet 2500-series van. The yellow metal tag states the model year and chassis. Before arriving at John Young’s garage, we disassembled the main components, leaving planetary gears intact, and used a friend’s spray-wash cabinet to clean the parts.

We started by removing the pan, filter, and valve body. It’s a relatively simple process, but it’s extremely important to keep track of all the little pieces. You’ll need one T40 torx bit and a skinny 12-point 10 mm. The center support bolt underneath the valve body, endures some abuse as it keeps the center support from spinning. The McLeod kit features a new replacement bolt.

Our kit included the Stage-1 Raybestos Performance friction plates with the upgraded Kolene steel plates. You don’t always need to replace steel clutch plates in a standard rebuild, but our new Kolene plates resist wear and fatigue between 200 to 500 percent better than stock. They have increased lubrication and feature improved heat retention, too.

Our original clutches (pictured right) are in such good condition that we may reuse them in a future stock rebuild. Still, the improvements from our new Raybestos plates are obvious. The OEM frictions friction plates are smooth to increase surface area, but that doesn’t do much for fluid travel and heat dissipation in a performance application. Our friction plates are grooved and textured for those reasons. The material and design compensate for that lack of surface area by providing a higher coefficient of friction.

John disassembled most everything but left the planetary gears intact. We checked for side play. Luckily, all were tight and didn’t require rebuilding. This is a four-pinion set, and a possible upgrade is a GM five-pinion, which spreads the torque load over a greater area. Bowler Transmissions upgrades to five-pinion (featured in a stock 4L85E) in their performance transmissions.

Steel clutch plates beat against the edges of the Fourth gear clutch housing/basket and cause slight ridges. We knocked down the high spots lightly with a file.

We coated all of our clutches in Redline Oil ATF before assembly. In previous transmission builds, we’ve assembled them dry. Which is the correct procedure? We asked Mark Bowler. “You ask ten transmission builders how to do something, you’ll get ten answers,” he says. Despite this, Bowler suggested you find a trustworthy transmission shop and research what questions to ask before arriving.

Here are some of the weak points in a standard 4L80E. The OEM input shaft is a commonly talked-about failure, as it produces carnage when it breaks. Based on Bowler’s 4L80E testing, the Overdrive sprag (the blue and black plastic ring, pictured right) is good up to 550 lb-ft and the stock input shaft, 600 lb-ft. The standard four-gear planetary is often upgraded to the five-gear unit used on the 4L85E.

The changes in diameter on the OEM shaft create weak points. Bowler’s 300M hardened input shaft features new ridges to spread the load more evenly. These are good for 1,000 lb-ft and are included in all of Bowler’s performance transmissions.

After carefully cleaning off the gasket material on the metal gasket, we took a file and lightly knocked down any ridges or marks. It’s important not to bend this gasket.

The valves in the valve body move under pressure. We did a simple visual check of the valves’ movements with an air gun.

The right way to check the valves’ movements is with a vacuum test, similar to a leak-down test on an engine. Pictured here is a vacuum tester at Bowler Transmissions, where they build four levels of transmissions varying from a stock 550 lb-ft rating to 1,000 lb-ft. Bowler believes the most overlooked way to improve transmission life is a well-serviced valve body. They typically ream and resize all the valves.

GM updated the Overdrive sprag in 1997, pictured left. Bowler upgrades all of their 4L80Es with the early, 1991—1995 sprag, pictured right.

We finished the build with a new brass filter, designed to clean better than a stock replacement. We’ll have to wait to see how it shifts, feels, and launches, but we have the option to go back and install a shift kit without removing the transmission.

Here is is the Sonnax Smart-Tech overrun clutch valve kit. It’s a hydraulic solution to a mechanical problem. The valve manifold (shown), reroutes hydraulic fluid pressure, keeping the overrun clutch applied at all times except in Fourth gear, reinforcing the roller clutch to support heavy loads adequately. You don’t have to remove the transmission to install it.
