ZF 0730.012.052 SHIM | OEM Genuine Part

Overview

The ZF 0730.012.052 SHIM is a precision-engineered OEM genuine part designed for critical axial clearance adjustment within ZF heavy-duty powershift transmissions. This shim sits between the transmission housing and bearing assemblies, ensuring correct preload and alignment of rotating components. The SKU 0730.012.052 is specifically used in construction machinery applications where vibration resistance and load distribution are paramount. By maintaining exact tolerances, this shim prevents metal-to-metal contact and extends the service life of adjacent components such as the 4699101153 HOUSING and 4699301250 HOUSING.

Symptoms of Failure

• Transmission gear slipping under load – Worn shims allow excessive axial play, causing clutch packs to disengage intermittently during heavy operation.
• Oil leaks from housing mating surfaces – A degraded shim disrupts the seal between the 4699309121 HOUSING COVER and main housing, leading to fluid seepage.
• Abnormal bearing noise or whining – Incorrect shim thickness creates bearing preload loss, resulting in audible metallic grinding during gear changes.
• Vibration through the driveline – Uneven shim wear causes shaft misalignment, transmitting harsh vibrations to the chassis at specific RPM ranges.

Technical Specifications

Compatibility

This shim is compatible with ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, excavators, and telehandlers. It also fits select ZF 4WG-200 and 6WG-200 variants used in construction machinery. Always verify the shim stack thickness requirement using the service manual for your specific transmission model. For assembly, ensure the 0636101411 CAP SCREW is torqued to factory specifications to maintain proper shim retention.
