Overview
The ZF 0630.000.067 SHIM RING is a precision-engineered spacer component designed for the WG 200 series of heavy-duty transmissions. This OEM genuine part, identified by SKU 0630.000.067, sits within the planetary gearset assembly, where it establishes critical axial clearances between rotating elements. By maintaining exact tolerances, this shim ring prevents metal-on-metal contact and ensures proper load distribution across the gear train. It is frequently replaced during a full transmission rebuild alongside the 4460115043: HOUSING and the 4469315012: AXLE DRIVE HOUSING to restore factory-spec endplay.
Symptoms of Failure
When the ZF 0630.000.067 shim ring wears or deforms, operators will notice distinct performance issues. The most common symptom is excessive axial play in the output shaft, which can be felt as a clunk during gear engagement. Another critical sign is intermittent gear slipping under load, particularly in lower gears, as the clearance allows the planetary gears to misalign. You may also detect low-frequency vibration or drone from the transmission housing during highway cruising. Finally, metal particles in the transmission fluid often appear as the shim ring wears against adjacent components like the 0750117406: TAPER ROLLER BEARING or the 0750117802: TAPERED ROLLER BEARING.

Compatibility
This shim ring is specifically engineered for the ZF WG 200 series, including models WG200, WG210, and WG220. It also fits select WG180 variants when used in conjunction with the correct 0734319337: SHAFT SEAL and 0730161317: WASHER kits. Always verify the thickness requirement using the factory service manual, as multiple shim thicknesses (0630.000.067 through 0630.000.075) are available for fine-tuning endplay. This part is not backward-compatible with older WG150 or WG160 units without housing modification.
