Overview
The ZF 0630.000.294 SHIM RING (SKU: 0630.000.294) is a precision-engineered OEM genuine component designed for critical axial clearance adjustment within heavy-duty ZF construction machinery transmissions. This hardened steel shim ring sits between the planetary gear carrier and the 4699101002 HOUSING assembly, ensuring correct preload on bearings and gear sets. By maintaining exacting tolerances, this shim ring prevents unwanted axial movement that can lead to premature wear of internal rotating assemblies. As a factory-specification part, it guarantees the precise thickness required for optimal transmission performance in demanding off-highway applications.
Symptoms of Failure
When the ZF 0630.000.294 shim ring wears or deforms, operators may notice these specific failure indicators:
- Excessive axial play in the output shaft – A worn shim ring allows the shaft to move back and forth, causing driveline vibration under load.
- Gear engagement noise during shifting – Incorrect clearance leads to clunking or grinding sounds when the transmission shifts between forward and reverse.
- Premature bearing failure – Without proper shim support, tapered roller bearings lose preload, generating heat and metallic debris in the oil.
- Oil seepage at housing joints – Axial movement can distort the 4699301188 HOUSING seal surface, leading to external leaks around the transmission case.

Compatibility
This OEM genuine shim ring is primarily used in ZF WG180, WG200, and WG210 series powershift transmissions found in wheel loaders, graders, and dozers. It also fits select ZF 4WG-200 and 6WG-200 variants where axial clearance adjustment between the output flange and 4699301128 COVER is required. For proper installation, always pair this shim with the 0636015047 HEXAGON SCREW to secure the retaining plate at the correct torque specification.
