ZF 0730.007.972 SHIM | OEM Genuine Part

Overview

The ZF 0730.007.972 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within ZF heavy-duty transmissions used in construction machinery. This thin, hardened steel shim sits between gear assemblies and bearing races, compensating for manufacturing tolerances to ensure optimal gear mesh and bearing preload. The SKU 0730.007.972 is essential for maintaining the exact spacing required for smooth power flow through the differential and final drive sections. Without this shim, adjacent components such as the 2095109016 DIFFERENTIAL and the 0750117075 TAPER ROLLER BEARING would experience excessive end-play or binding, leading to accelerated wear and premature failure.

Symptoms of Failure

• Oil leaks around the axle housing: A worn or collapsed shim allows the 2095209037 DIFFERENTIAL to shift, breaking the seal between the housing and the 2095309059 DIFF.HOUSING, causing gear oil to weep out.
• Gear slipping under load: Incorrect shim thickness reduces bearing preload, allowing the taper roller bearing to lose contact with the race, resulting in momentary power loss during heavy digging or lifting.
• Metallic grinding noise from the transmission: As the shim wears, gear teeth lose proper alignment, creating a harsh, cyclical grinding sound that worsens with speed.
• Vibration in the driveline: A degraded shim permits axial movement of the differential assembly, transmitting low-frequency vibrations through the chassis during operation.

Technical Specifications

Compatibility

This shim is specifically engineered for ZF transmissions commonly installed in wheel loaders, excavators, and telehandlers. Based on its dimensions and function, the 0730.007.972 is compatible with the following ZF transmission models:

• ZF WG180 (all series)
• ZF WG200 (all series)
• ZF WG310 (early production)
• ZF 4WG-200
• ZF 6WG-250 (differential section)

Always verify the shim stack height using a micrometer when replacing this part alongside the 2095109016 DIFFERENTIAL or the 0750117075 TAPER ROLLER BEARING to ensure proper preload.
