Overview
The ZF 0730.102.336 SHIM is a precision-engineered spacer component designed for the WG 201 series of heavy-duty transmissions. This OEM genuine part plays a critical role in maintaining correct axial clearance and preload within the planetary gearset assembly. By ensuring exact end-play tolerances, the shim prevents gear misalignment and reduces wear on adjacent bearings. The SKU 0730.102.336 is a factory-specified shim, guaranteeing a perfect fit for your ZF transmission rebuild or repair. It is installed directly between the transmission housing and the bearing race, making it essential for proper torque distribution.
Symptoms of Failure
- Oil leaks around the housing joint: A worn or incorrect shim can cause uneven clamping force, leading to fluid seepage between the TRANSMISSION HOUSING and the TRANSMISSION HOUSING sections.
- Gear slipping under load: Excessive axial play from a collapsed shim reduces gear engagement depth, causing intermittent slipping during acceleration.
- Metallic grinding noise from the gearset: When the shim fails to maintain proper preload, gear teeth clash, producing a distinct grinding sound during shifts.
- Premature bearing failure: Incorrect shim thickness leads to bearing race misalignment, accelerating wear on the O-RING and SEALING RING.

Compatibility
This shim is specifically engineered for the ZF WG 201 series transmissions. It is also compatible with the closely related WG180, WG200, and WG210 models where identical planetary gearset clearances are required. For proper installation, ensure the mating surfaces on the THREADED BUSH and SCREW PLUG are clean and free of debris. Always verify the shim thickness against your transmission’s service manual to avoid over-tightening.
