ZF 0730.111.805 SHIM | OEM Genuine Part

Overview

The ZF 0730.111.805 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearance within heavy-duty ZF transmission assemblies. This shim sits between the differential housing and bearing races, ensuring correct preload and alignment of rotating components. The SKU 0730.111.805 is specifically utilized in construction machinery transmissions, where it compensates for manufacturing tolerances and prevents metal-to-metal contact under high torque loads. By maintaining exact spacing, this shim directly supports the longevity of adjacent components such as the 2093109029 DIFFERENTIAL and the 0750117075 TAPER ROLLER BEARING.

Symptoms of Failure

• Excessive differential backlash: A worn or collapsed shim allows the 2093209094 DIFFERENTIAL to shift axially, causing clunking noises during direction changes—a common “ZF transmission gear slipping” complaint.
• Oil seepage at axle flanges: Incorrect shim thickness distorts the 2093309078 DIFF.HOUSING seal surface, leading to “construction machinery axle oil leaks” that require immediate attention.
• Premature bearing wear: Without proper shim support, the taper roller bearing experiences uneven load distribution, generating metallic debris in the transmission fluid—a clear “ZF differential bearing failure” indicator.
• Vibration under load: A degraded shim permits radial movement of the differential assembly, causing “heavy equipment driveline vibration” during excavation or grading operations.

Technical Specifications

Compatibility

This shim is engineered for ZF heavy-duty powershift transmissions commonly found in construction machinery. Based on its dimensional profile and application, the 0730.111.805 is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG250. It is also used in certain ZF differential assemblies for wheel loaders and graders. Always verify fitment with your specific transmission serial number, as shim thickness may vary by application.

Frequently Asked Questions

Q: Can I reuse the 0730.111.805 shim during a rebuild?
A: No. ZF OEM shims are single-use components designed to deform slightly during installation to achieve proper seating. Reusing a shim can lead to incorrect preload and premature failure of the differential assembly.

Q: How do I measure the correct shim thickness for my ZF transmission?
A: Use a depth micrometer to measure the distance between the bearing race and the differential housing face. Subtract the desired bearing preload (typically 0.05–0.10 mm) from this measurement to determine the required shim thickness. Always consult the ZF service manual for your specific model.

Q: Is this shim compatible with aftermarket differentials?
A: The 0730.111.805 is dimensionally matched to OEM ZF differentials. Aftermarket units may have different housing depths, so we recommend using this shim only with genuine ZF components like the 2093109029 DIFFERENTIAL to ensure correct fitment.
