Overview
The ZF 0630.000.037 SHIM RING (SKU: 0630.000.037) is a precision-engineered OEM genuine component designed for critical axial clearance adjustment within ZF construction machinery transmissions. This shim ring sits directly between the 4108101112: HOUSING and the planetary gear set, ensuring correct preload on bearings and gear assemblies. By maintaining exacting tolerances, this part prevents unwanted axial movement that can lead to premature wear of internal components. The shim ring is manufactured from high-strength steel to withstand the extreme loads and thermal cycling typical in heavy-duty construction equipment.
Symptoms of Failure
- Excessive transmission end-play or axial movement – When the shim ring wears or compresses beyond specification, you may detect a noticeable clunking or knocking sound during gear engagement, especially under load.
- Oil leaks at housing joints – A degraded shim ring can cause misalignment between the 4108201177: HOUSING and the bearing cover, leading to seal distortion and fluid seepage.
- Gear slipping or delayed engagement – Incorrect shim thickness alters clutch pack clearance, resulting in soft shifts or slipping under torque.
- Vibration and bearing noise – Loss of proper preload allows the 0635332196: BALL BEARING to operate outside its designed tolerance, generating harmonic vibration.

Compatibility
This shim ring is primarily used in ZF WG180, WG200, and WG310 series transmissions found in wheel loaders, graders, and excavators. It is also applicable to certain ZF Ecomat and Ecolife models where axial clearance adjustment is required between the 4108301304: BEARING COVER and the 4108302099: PLANET CARRIER. Always verify your transmission model and serial number before ordering.
During installation, it is common to replace the 0636302056: SCREW PLUG and the 4108306173: GASKET to ensure a leak-free seal. The 0750110040: SHAFT SEAL should also be inspected for wear when accessing this area.
