ZF 0730.112.608 SHIM | OEM Genuine Part

Overview

The ZF 0730.112.608 SHIM is a precision-engineered OEM genuine part designed to establish exact axial clearances within ZF heavy-duty transmissions. This shim sits between the differential housing and the crown wheel assembly, ensuring the gear mesh depth remains within factory tolerances. The SKU 0730.112.608 is critical for maintaining proper preload on the differential bearings, directly influencing torque distribution and drivetrain longevity. Without this shim, the entire differential assembly—including the 2099109002 DIFFERENTIAL and 2099364014 CROWN WHEEL—cannot achieve the precise alignment required for smooth power transfer in construction machinery.

Symptoms of Failure

• Excessive gear backlash and clunking on acceleration: When the 0730.112.608 shim wears or compresses beyond spec, the 2099209001 DIFFERENTIAL gears lose their tight mesh, producing audible knocking during load changes.
• Premature crown wheel tooth wear: Incorrect shim thickness forces the 2099364014 CROWN WHEEL to contact the pinion at an improper angle, accelerating pitting and spalling.
• Oil leaks from the differential housing seal: Worn shims allow the 2098309010 DIFFERENTIAL HOUSING to shift, distorting the seal surface and causing fluid seepage around the axle flange.
• Vibration at steady highway speeds: A degraded shim introduces micro-movement in the differential carrier, transmitting harmonic vibrations through the driveline.

Technical Specifications

Compatibility

This shim is engineered for ZF’s WG series powershift transmissions commonly used in wheel loaders and graders. It fits the following models: WG180, WG200, WG210, and WG250. The 0730.112.608 is also found in certain ZF TC-Tronic torque converter transmissions paired with 2098309010 DIFFERENTIAL HOUSING assemblies. Always verify the shim stack height when replacing the 2099364014 CROWN WHEEL or 2099109002 DIFFERENTIAL to maintain factory preload specifications.
