ZF 0730.112.611 SHIM | OEM Genuine Part

Overview

The ZF 0730.112.611 SHIM is a precision-engineered OEM genuine spacer component designed to establish critical axial clearances within heavy-duty ZF transmission assemblies. This shim sits between the differential housing and the crown wheel or bevel gear stack, ensuring optimal gear mesh patterns and preload settings. The SKU 0730.112.611 is a factory-specified thickness element that directly influences bearing end-play and gear alignment. Without this shim, the entire differential assembly—including the 2099109002 DIFFERENTIAL and the 2099364014 CROWN WHEEL—cannot achieve the tight tolerances required for smooth power transfer in construction machinery transmissions.

Symptoms of Failure

• Excessive differential backlash and gear clunking – When the 0730.112.611 shim compresses or wears, the 2099209001 DIFFERENTIAL loses its preload, causing audible knocking during load shifts.
• Premature bearing failure from improper preload – A collapsed shim allows the 2098309010 DIFFERENTIAL HOUSING to shift, leading to uneven bearing wear and eventual seizure.
• Oil contamination with metallic debris – Worn shim material flakes off into the transmission fluid, often mistaken for gear tooth spalling. This is a common long-tail search query for “ZF transmission metal shavings in oil.”
• Intermittent gear slipping under heavy load – Incorrect shim thickness causes the crown wheel to walk out of mesh, resulting in momentary power loss during excavation or grading operations.

Technical Specifications

Compatibility

This shim is primarily used in ZF WG180, WG200, and WG250 series transmissions found in wheel loaders, telehandlers, and graders. It also applies to select ZF 4WG-200 and 6WG-200 variants where the differential assembly requires fine axial adjustment. The 0730.112.611 is frequently paired with the 2098309031 AXLE BEVEL GEAR and 2098309030 AXLE BEVEL GEAR in the final drive stack. Always verify shim count and thickness against the service manual for your specific transmission model.
