Overview
The ZF 4607.316.081 SHIM is a precision-engineered adjustment component designed specifically for the WG 65 series of heavy-duty transmissions. This OEM genuine part functions as a critical spacer within the planetary gearset assembly, controlling axial clearance and ensuring correct load distribution across bearings and clutch packs. By maintaining precise end-play tolerances, the shim prevents premature wear on adjacent components. The SKU 4607.316.081 is manufactured to ZF’s exacting specifications, guaranteeing a perfect fit when installed alongside the TRANSMISSION HOUSING and secured with the appropriate HEXAGON SCREW fasteners.
Symptoms of Failure
When the 4607.316.081 shim wears or becomes compressed beyond tolerance, operators may notice distinct operational issues. Transmission gear slipping under load is a primary indicator, as incorrect shim thickness allows planetary gears to shift out of alignment. Abnormal whining or grinding noises from the transmission housing often accompany this condition, particularly during acceleration or deceleration. Delayed or harsh gear engagement occurs when axial play exceeds specifications, causing clutch packs to engage unevenly. Finally, visible metal particles in the transmission fluid may appear as the shim surface degrades, contaminating the oil system.
