ZF 0630.004.067 SHIM RING for WG150 | OEM Genuine Part

Overview

The ZF 0630.004.067 SHIM RING is a precision-engineered spacer component designed for the WG 150 series transmission. This OEM genuine part plays a critical role in establishing the correct axial clearance between rotating assemblies and the transmission housing. By maintaining precise end-play tolerances, the shim ring prevents internal gear clash and ensures smooth power flow through the planetary gear sets. The SKU 0630.004.067 is machined to exacting ZF specifications, making it an essential element during rebuilds or when replacing the 4642101108: TRANSMISSION HOUSING or the 4642301208: TRANSMISSION HOUSING.

Symptoms of Failure

When the ZF 0630.004.067 shim ring wears or is incorrectly installed, several distinct failure modes emerge. Transmission gear slipping under load is a primary indicator, as excessive axial play allows clutch packs to disengage momentarily. Low-frequency humming or rumbling from the WG150 housing often signals that the shim ring has thinned beyond tolerance, allowing gear teeth to contact improperly. Metallic debris in the transmission oil filter can also appear as the ring wears against adjacent surfaces. Finally, difficulty engaging reverse or forward gears may occur when the shim ring fails to maintain the correct stack height, a condition often misdiagnosed as a valve body issue.

Technical Specifications

Compatibility

This shim ring is primarily specified for the ZF WG 150 series transmissions. It also fits the WG 180 and WG 200 models when used in conjunction with the correct 0730365125: TYPE PLATE to verify the build configuration. For WG 250 and WG 300 variants, the ring may be used as a selective fit component during overhaul. Always cross-reference the original shim thickness when replacing the 0631311009: GROOVED STUD or other fasteners in the clutch drum assembly.
