Overview
The ZF 0730.106.657 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within heavy-duty ZF transmissions. This shim sits between the differential housing and the bearing seat, ensuring correct preload on the gear train. The SKU 0730.106.657 is specifically used to adjust end-play in the differential assembly, preventing unwanted movement that leads to premature wear. Without this shim, the entire drivetrain loses its dimensional stability, causing misalignment of the 2093109029: DIFFERENTIAL and adjacent components.
Symptoms of Failure
- Excessive drivetrain backlash: When the shim compresses or wears, you will notice a clunking sound during direction changes, especially in construction machinery operating under load.
- Oil leaks near the differential housing: A worn shim allows the 0750117075: TAPER ROLLER BEARING to shift, breaking the seal and causing fluid seepage.
- Gear slipping under torque: Loss of correct shim thickness reduces bearing preload, leading to intermittent power loss during heavy excavation or lifting operations.
- Vibration at the axle: A collapsed shim creates axial play that transmits vibration through the 2093209094: DIFFERENTIAL assembly, felt as a rhythmic shudder in the cab.

Frequently Asked Questions
Q: Can I reuse the ZF 0730.106.657 shim after disassembly?
A: No. This shim is a single-use component. It compresses during initial torque application and must be replaced to maintain correct preload. Reusing it will lead to rapid wear of the taper roller bearing and differential.
Q: How do I know if I need a thicker or thinner shim?
A: Measure the axial play after installing the differential housing. If play exceeds 0.10 mm, use a thicker shim. If the assembly binds, use a thinner shim. Always stack shims on the same side of the bearing race.
Q: Does this shim fit ZF WG180 transmissions from 1998?
A: Yes, the 0730.106.657 shim is backward-compatible with WG180, WG200, and WG250 transmissions manufactured from 1995 onward, provided the differential housing bore is 85 mm.
