Overview
The ZF 0730.111.807 SHIM (SKU: 0730.111.807) is a precision-engineered OEM genuine spacer component designed to maintain critical axial clearances within ZF heavy-duty transmission assemblies. Positioned between the differential housing and bearing races, this shim compensates for manufacturing tolerances and thermal expansion, ensuring optimal gear mesh and load distribution. As a non-rotating component, it directly influences the preload on the 0750117075: TAPER ROLLER BEARING, preventing premature wear in the differential section. This part is critical for maintaining the structural integrity of the final drive assembly in construction machinery transmissions.
Symptoms of Failure
- Excessive differential backlash – When the shim compresses or fractures, you may notice a clunking noise during direction changes, indicating lost preload on the 2093109029: DIFFERENTIAL assembly.
- Oil seepage from axle seals – A worn shim alters the bearing preload, causing the 2093309078: DIFF.HOUSING to shift slightly, leading to seal distortion and fluid leaks.
- Vibration under load – Incorrect shim thickness allows the 2093209094: DIFFERENTIAL to wobble, generating low-frequency vibrations felt through the chassis during excavation or grading operations.
- Metal debris in transmission oil – A collapsed shim permits metal-on-metal contact between the differential carrier and housing, producing fine steel particles detectable during routine oil analysis.

Compatibility
This shim is engineered for use in ZF power-shift transmissions commonly found in wheel loaders, dozers, and graders. It is specifically compatible with the WG180, WG200, and WG211 series, where it sits between the differential carrier and the taper roller bearing race. It also fits the 4WG-200 and 5WG-200 variants used in heavy construction machinery. Always verify the existing shim thickness before replacement, as selective fit tolerances require precise measurement with a micrometer.

Frequently Asked Questions
Q: Can I reuse the old shim if it looks undamaged?
No. Shims work-harden over time and lose their precise thickness. Always install a new OEM shim (0730.111.807) to maintain proper bearing preload and avoid differential failure.
Q: How do I measure the correct shim thickness for my WG200 transmission?
Use a depth micrometer to measure the distance from the bearing bore shoulder to the differential carrier face. Subtract the bearing width and desired preload (typically 0.05–0.10 mm) to select the appropriate shim from the selective fit range.
Q: Is this shim interchangeable between WG180 and WG211 models?
Yes, the 0730.111.807 shim shares the same outer and inner diameter across these series, but always verify the housing depth as minor casting variations exist between model years.
