Overview
The ZF 0630.000.162 SHIM RING is a precision-engineered spacer component designed for the WG 200 Series transmission. This OEM genuine part plays a critical role in establishing the correct axial clearance and preload within the planetary gear set assembly. By maintaining exact tolerances, the shim ring ensures that rotating elements, such as the 0750117406: TAPER ROLLER BEARING, operate without excessive end-play or binding. The SKU 0630.000.162 is specifically calibrated to fit the output shaft region, where it interfaces directly with the main 4460115043: HOUSING to secure gear alignment under heavy torque loads.
Symptoms of Failure
- Audible whining or grinding from the transmission case: When the shim ring wears or deforms, the 0750117802: TAPERED ROLLER BEARING loses its proper preload, causing metal-on-metal contact that generates a distinct high-pitched noise during acceleration.
- Oil seepage around the axle drive housing interface: A collapsed shim ring alters the sealing gap, leading to fluid migration past the 4469315012: AXLE DRIVE HOUSING and resulting in visible drips or wet spots on the transmission exterior.
- Intermittent gear slippage under load: Incorrect axial play from a worn 0630.000.162 allows the planetary carrier to shift, causing momentary loss of torque transfer during uphill climbs or towing operations.
- Vibration in the driveline at highway speeds: As the shim ring fatigues, rotational imbalance develops within the gear stack, transmitting noticeable shudder through the chassis at 45–65 mph.

Compatibility
This shim ring is engineered for the ZF WG 200 Series transmissions, including the WG180, WG200, and WG210 variants. It is also utilized in select off-highway and marine gearboxes that share the same planetary carrier architecture. The 0630.000.162 is frequently replaced during a full bearing overhaul, where it is paired with the 0734319337: SHAFT SEAL to restore oil retention integrity. Always verify the axial clearance specification for your specific transmission model before installation.
