ZF 0630.004.203 SHIM RING for WG200 | OEM Genuine Part

Overview

The ZF 0630.004.203 SHIM RING is a precision-engineered spacer component designed for the WG 200 Series transmission family. This OEM genuine part plays a critical role in establishing the correct axial clearance and preload within the gear train assembly. By maintaining precise tolerances between rotating and stationary components, the shim ring ensures optimal load distribution and prevents metal-to-metal contact. The SKU 0630.004.203 is specifically calibrated for the WG200’s planetary gear sets, where it sits between the 4460115043: HOUSING and the output shaft assembly to control end-play.

Symptoms of Failure

When the ZF 0630.004.203 shim ring wears or deforms, several distinct failure modes emerge. Excessive axial play in the output shaft is a primary indicator, often felt as a clunking sensation during gear engagement. Premature bearing noise—a whining or grinding sound under load—occurs because the 0750117406: TAPER ROLLER BEARING loses its correct preload. Intermittent gear slippage in higher ranges can develop as the shim ring’s thickness degrades, altering clutch pack clearances. Oil contamination from metallic debris in the transmission pan is another telltale sign, as the worn ring generates fine steel particles that circulate through the system.

Technical Specifications

Compatibility

This shim ring is primarily designed for the ZF WG 200 Series transmissions, including the WG200, WG210, and WG220 variants. It also fits select WG180 models produced after 2012, where the output shaft housing geometry matches. The part is not interchangeable with the WG150 or WG250 series due to differing bearing seat diameters. When replacing this shim, always inspect the mating 4469315012: AXLE DRIVE HOUSING for wear, and verify the condition of the 0750117802: TAPERED ROLLER BEARING which directly interfaces with the shim ring’s seating surface.
