ZF 0730.112.610 SHIM | OEM Genuine Part

Overview

The ZF 0730.112.610 SHIM is a precision-engineered OEM genuine spacer used to establish critical axial clearances within heavy-duty ZF transmissions. Positioned between the differential housing and the crown wheel assembly, this shim compensates for manufacturing tolerances and wear, ensuring correct gear mesh and load distribution. The SKU 0730.112.610 is specifically designed for construction machinery drivelines, where vibration and high torque demand exacting tolerances. Without this shim, the differential and crown wheel components cannot maintain proper alignment, leading to premature failure of the entire axle assembly.

Symptoms of Failure

• Excessive driveline backlash – A worn or collapsed shim allows the differential to shift, creating a clunking noise when changing direction under load.
• Oil leaks from the axle housing – Incorrect shim thickness distorts the differential housing seal surface, causing gear oil seepage around the DIFFERENTIAL HOUSING.
• Gear whine during acceleration – Loss of shim thickness alters the contact pattern between the CROWN WHEEL and pinion, producing a high-pitched metallic noise.
• Premature bearing failure – Axial play from a degraded shim overloads the BALL BEARING sets, leading to rough rotation and eventual seizure.

Technical Specifications

Compatibility

This shim is engineered for ZF heavy-duty transmissions commonly used in construction machinery. It is a direct fit for the following models: WG180, WG200, WG210, and WG250 series. It also applies to select AP400 and AP500 axle configurations where the DIFFERENTIAL assembly uses a 112 mm outer diameter shim pocket. Always verify the existing shim thickness before replacement, as selective fit shims are matched to the DIFFERENTIAL and crown wheel stack height during factory assembly.
