Overview
The ZF 0730.110.771 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within ZF heavy-duty powershift transmissions. This shim sits between the differential housing and bearing races, ensuring correct preload on the 0750117075: TAPER ROLLER BEARING assembly. By maintaining exact spacing, the 0730.110.771 prevents gear train misalignment and protects the 5838109007: DIFFERENTIAL from excessive end-play. This SKU is a factory-spec shim, not a generic substitute, guaranteeing dimensional consistency for rebuilds of construction machinery transmissions.
Symptoms of Failure
- Transmission oil leaks at the differential housing: A worn or collapsed shim allows the taper roller bearing to shift, breaking the seal between the housing and output shaft, leading to visible fluid seepage.
- Gear slipping under load in forward/reverse: Incorrect shim thickness reduces bearing preload, causing the 2095209019: DIFFERENTIAL to wobble, which manifests as intermittent power loss during excavation or grading operations.
- Metallic grinding noise from the transmission sump: When the shim wears paper-thin, the taper roller bearing inner race contacts the housing directly, producing a distinct high-pitched grinding sound during deceleration.
- Vibration through the driveline at low RPM: Loss of axial control from a degraded shim allows the differential assembly to oscillate, transmitting harsh vibrations to the chassis during idle creep.

Compatibility
This shim is engineered for ZF powershift transmissions commonly used in wheel loaders, graders, and telehandlers. It is a direct fit for the following ZF models: WG180, WG200, WG210, and WG310. The 0730.110.771 is also applicable to select 4WG-200 and 6WG-310 series where the differential carrier uses a taper roller bearing arrangement. Always verify the shim stack height during rebuild; this part is often paired with the 0631329086: SPRING PIN that secures the differential lock mechanism.
