ZF 0730.002.567 SHIM | OEM Genuine Part

Overview

The ZF 0730.002.567 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within heavy-duty construction machinery transmissions. This thin, hardened steel component sits between the transmission housing and bearing assemblies, compensating for manufacturing tolerances to ensure optimal gear mesh and shaft alignment. The SKU 0730.002.567 is specifically calibrated to maintain preload specifications, preventing unwanted movement that can lead to premature wear. When installed alongside a TRANSMISSION HOUSING, this shim guarantees the exact spacing required for smooth power flow under extreme loads.

Symptoms of Failure

• Transmission gear slipping under load – A worn or collapsed shim allows excessive end-play, causing gears to lose engagement during heavy excavation or lifting operations.
• Low-frequency humming or vibration from the drivetrain – Incorrect shim thickness permits bearing race misalignment, generating resonant noise that intensifies with RPM.
• Oil contamination with metallic debris – As the shim degrades, it sheds fine steel particles into the lubricant, often visible during routine oil sampling.
• Hard shifting or delayed engagement – Axial play from a failed shim disrupts clutch pack clearance, leading to sluggish or jerky gear changes in wheel loaders and dozers.

Technical Specifications

Compatibility

This shim is engineered for ZF heavy-duty powershift transmissions commonly found in construction machinery. It is a direct fit for the WG180, WG200, and WG250 series, as well as the 4WG-200 and 5WG-250 variants. The 0730.002.567 also applies to select Ecomat and Ergopower models used in excavators and graders. For proper installation, always pair this shim with a new HOUSING gasket surface and verify clearance using the adjacent HOUSING component. Secure the assembly with a SCREW PLUG torqued to factory specifications.
