ZF 0630.000.118 SHIM RING for WG65 | OEM Genuine Part

Overview

The ZF 0630.000.118 SHIM RING is a precision-engineered spacer component designed for the WG 65 Series transmission. This OEM genuine part plays a critical role in establishing the correct axial clearance between rotating assemblies and stationary housings within the gear train. By maintaining precise end-play tolerances, the shim ring prevents gear clash and ensures smooth power transfer under heavy loads. The SKU 0630.000.118 is manufactured to ZF’s exacting specifications, guaranteeing a direct fit without modification. When installed alongside a TRANSMISSION HOUSING, this shim ring helps maintain structural integrity and oil flow paths within the WG65 unit.

Symptoms of Failure

• Excessive axial play or gear rattle: A worn or collapsed shim ring allows the gear cluster to shift, producing a distinct metallic knocking sound during acceleration or deceleration.
• Oil leaks at housing seams: Incorrect clearance from a degraded shim ring can distort the housing seal surface, leading to fluid seepage around the HEXAGON SCREW mounting points.
• Hard shifting or gear slipping: When the shim ring fails to maintain proper end-play, synchronizer engagement becomes inconsistent, causing delayed or missed shifts under load.
• Vibration during operation: A fatigued shim ring allows the shaft assembly to oscillate, transmitting vibration through the HEXAGON SCREW connections to the chassis.

Technical Specifications

Compatibility

This shim ring is primarily engineered for the WG 65 Series transmission family, which includes models such as the WG180, WG200, and WG250. It is also compatible with certain WG65 variants used in off-highway trucks and construction equipment. The part is designed to work in conjunction with the HEXAGON SCREW fasteners that secure the bearing retainer. For precise fitment, always verify the transmission serial number against ZF’s parts catalog.
