When your motorcycle or manual transmission vehicle begins to exhibit notched gear shifts, a heavy clutch lever feel, or an audible grinding sensation when engaging the clutch, the culprit is often a worn clutch fork shaft bearing. This small but critical component acts as the pivot point for the clutch fork, translating your lever pull into the mechanical movement required to disengage the clutch plates. Because this part sits at the intersection of high-pressure mechanical force and rotational friction, selecting a replacement that meets or exceeds original equipment specifications is vital for smooth shifting and long-term transmission health.

Throwout Bearing,Clutch Fork & Boot,Pivot Ball (4pcs) FIT: 1964-1988 , Malibu, Monte Carlo* 1959-1987 El Camino* 1959-1988 Impala, Caprice, Bel Air, Biscayne, Brookwood, Kingswood, Nomad, Sedan Delivery* 1963-1981 Corvette* 1967-1981 Camaro* 1968-1974 II, Nova*
With Manual Transmissions & 168 tooth Flywheel
Will not work on 1962-1967 Chevy II & Chevy Nova models as the size of the transmission tunnel is too narrow.
Will not work on Monza or Vega as they both used a cable operated 10.5" clutch with the pivot on the other side. The clutch fork was also angled about 45 degrees not straight across.
Works with GM transmissions with a 4.675" O.D. Bearing Retainer. Clears 168 tooth 14" Flywheels with factory 11" Clutch Discs. 1/2"-13 tapped hole for z-bar manual clutch linkage, if needed. Fits ALL Small Block & Big Block Chevy engines regardless of factory clutch size
The YHB GM Throwout Bearing and Clutch Fork Kit is a comprehensive four-piece solution for anyone restoring a classic Small Block or Big Block Chevy. This set is specifically engineered to clear 168-tooth flywheels and works seamlessly with GM transmissions featuring a 4.675" O.D. bearing retainer. It covers a massive range of vintage muscle, including everything from Corvettes to Camaros, provided you are running a manual transmission with a factory 11" clutch disc. Just keep in mind that this won't fit the narrower transmission tunnels of 1962-1967 Chevy II models, nor is it compatible with the cable-operated systems found in Monza or Vega models. If your setup requires a 1/2"-13 tapped hole for z-bar linkage, this kit has you covered for a smooth, reliable engagement.
Any driver facing a slipping or noisy clutch needs to stop looking for cheap alternatives and invest in this TIMKEN release bearing immediately. This component is a lifesaver for anyone wanting to restore smooth gear transitions because it specifically targets the friction between your pressure plate levers and the release fork. By utilizing high-quality materials designed to resist fatigue failure, it handles the heavy lifting of torque and power transmission without breaking a sweat. I love that it offers original equipment quality, meaning you aren't settling for a subpar aftermarket part that will fail in six months. It provides the long-lasting durability required for demanding driving conditions, making it a reliable cornerstone for your drivetrain maintenance.

A Guide to Selecting the Best clutch fork shaft bearings
Understanding Material Composition and Durability
The primary job of a clutch fork shaft bearing is to handle radial loads while maintaining smooth movement under varying temperatures. When browsing options, look closely at the material of the inner and outer races. High-quality bearings utilize hardened chrome steel, which resists the pitting and spalling caused by the constant pressure of the clutch spring preload. If you are working on a high-performance or racing application, you might encounter bearings with ceramic components. While more expensive, ceramic balls offer significantly lower friction and higher heat resistance, which can prevent the 'sticky' clutch feeling that occurs when components expand due to heat soak.
Precision Tolerances and Fitment Accuracy
In the world of clutch assemblies, there is zero margin for error. A bearing that is even a fraction of a millimeter too tight will cause excessive drag, making it difficult to fully disengage the clutch and potentially causing the vehicle to creep forward while idling. Conversely, a bearing that is too loose will introduce 'slop' into the system, leading to imprecise gear engagement and increased wear on the clutch fork itself. Always prioritize bearings that specify high-precision tolerances. If you are rebuilding a vintage machine, ensure the bearing is designed to match the specific shaft diameter of your original fork assembly, as aftermarket variations can sometimes deviate from factory standards.
Sealing Technology and Contamination Resistance
The environment inside a clutch housing is not as clean as it might seem. It is often subject to oil mist, clutch plate dust, and microscopic debris. A bearing with superior sealing is essential to prevent these contaminants from entering the race and causing premature failure. Look for bearings equipped with high-quality contact seals or shields. Contact seals provide the best protection against ingress by creating a physical barrier, though they do introduce slightly more friction than non-contact shields. For most street-driven motorcycles, a shielded bearing provides the perfect balance of protection and smooth, low-effort operation.
Load Capacity and Application Matching
Not all clutch fork shaft bearings are created equal. The load requirements for a heavy touring motorcycle are vastly different from those of a lightweight sportbike. When making your decision, consider the torque profile of your engine. High-torque engines put significantly more stress on the clutch fork assembly during engagement. Select a bearing with a dynamic load rating that accounts for these stresses. If you are performing a complete clutch overhaul, it is highly recommended to replace the bearing even if it hasn't failed yet, as the cost of the part is negligible compared to the labor required to re-open the engine case later.

Quick answers about Clutch Fork Shaft Bearings before you buy.
It allows the clutch fork to pivot smoothly around the shaft, ensuring consistent engagement and disengagement of the clutch mechanism while reducing friction and wear.
Common symptoms include a notched or 'notchy' feel when pulling the clutch lever, unusual grinding noises during shifting, or difficulty finding neutral.
Generally, no. Most clutch fork shafts require needle roller bearings because they are designed to handle high radial loads within a very narrow, compact space.
There is no fixed interval, but they should be inspected during every clutch service or whenever you notice resistance in the clutch lever action.
Yes. Using high-quality, heat-resistant grease is essential to prevent metal-on-metal contact and to protect the bearing from the high temperatures generated near the engine.
Look for hardened steel races, high-precision tolerances, and specialized cages that can withstand the rapid, repetitive movements of the clutch linkage.
While it won't change the transmission's internal mechanics, a smoother bearing reduces lever effort and hesitation, leading to more precise and consistent clutch modulation.
Not necessarily, but you must inspect the shaft for scoring or grooves. If the shaft surface is damaged, a new bearing will fail prematurely due to uneven contact.
