ZF 0730.112.808 SHIM | OEM Genuine Part

Overview

The ZF 0730.112.808 SHIM is a precision-engineered OEM genuine part designed to establish the correct axial clearance and preload within heavy-duty ZF transmission assemblies. This shim sits between the differential housing and bearing races, ensuring that gear meshing remains within factory tolerances. The SKU 0730.112.808 is critical for maintaining the structural integrity of the drivetrain, particularly in construction machinery transmissions where load stresses are extreme. By compensating for manufacturing tolerances, this shim prevents excessive movement of components such as the 2095109020 DIFFERENTIAL and the 2095209037 DIFFERENTIAL, ensuring long-term reliability under high torque conditions.

Symptoms of Failure

• Excessive drivetrain backlash: When the 0730.112.808 shim wears or compresses beyond spec, you will notice a delayed engagement or “clunking” sound when shifting between forward and reverse gears in your ZF transmission.
• Premature bearing noise: A worn shim allows the 0750117075 TAPER ROLLER BEARING to operate outside its designed preload, producing a distinct whining or grinding noise that increases with vehicle speed.
• Oil contamination from metal debris: As the shim degrades, microscopic metal particles enter the transmission fluid, often visible during routine oil changes as a metallic sheen or sludge in the filter.
• Intermittent gear slipping under load: Loss of correct shim thickness causes the 2095309059 DIFF.HOUSING to shift position, leading to momentary loss of power transfer during heavy excavation or grading operations.

Technical Specifications

Compatibility

This shim is engineered for use in ZF heavy-duty powershift transmissions commonly deployed in construction machinery. It is a direct fit for the following ZF transmission models: WG180, WG200, WG210, and WG250 series. The 0730.112.808 is also compatible with select ZF Ecomat and Ecolife variants where differential preload adjustment is required. Always verify the shim stack height against the service manual when replacing the 2095309059 DIFF.HOUSING or the 2095109020 DIFFERENTIAL to ensure correct end-play.
