Overview
The ZF 0630.004.014 SHIM RING is a precision-engineered spacer component designed for the WG 200 Series transmission family. This OEM genuine part ensures correct axial clearance and load distribution between the planetary gear sets and the transmission housing. By maintaining exacting tolerances, the shim ring prevents metal-on-metal contact and supports optimal gear mesh alignment. The SKU 0630.004.014 is installed directly within the main gear train assembly, often adjacent to the 4644101165: TRANSMISSION HOUSING and the 4644301304: HOUSING, where it acts as a critical wear buffer.
Symptoms of Failure
- Transmission oil leaks around the bell housing: A worn or collapsed shim ring can cause misalignment, leading to seal gaps and fluid seepage.
- Gear slipping under load: When the shim ring loses its thickness, axial play increases, causing intermittent gear disengagement during acceleration.
- Abnormal whining or grinding noises: Insufficient shim support allows gear teeth to contact unevenly, producing audible metallic sounds from the transmission case.
- Delayed engagement when shifting: Worn axial clearance can interfere with hydraulic pressure paths, resulting in sluggish clutch pack application.

Compatibility
This shim ring is primarily designed for the ZF WG 200 Series transmissions. It is also compatible with the WG 180 Series and certain variants of the WG 210 Series where the same planetary carrier assembly is used. The part interfaces directly with the 0730365067: TYPE PLATE for identification and the 0631311009: GROOVED STUD for secure mounting. Always verify your transmission model number before ordering.
