ZF 0630.000.182 SHIM RING for WG65 | OEM Genuine Part

Overview

The ZF 0630.000.182 SHIM RING is a precision-engineered spacer component designed for the WG 65 Series transmission. This OEM genuine part ensures correct axial clearance and load distribution between rotating assemblies within the gearbox. Positioned between the planetary carrier and the output shaft hub, the shim ring maintains optimal gear mesh alignment and prevents metal-on-metal contact during high-torque operations. The SKU 0630.000.182 is factory-specified to exact thickness tolerances, making it critical for rebuilds and overhauls of heavy-duty ZF transmissions. When paired with a new 4616105413: OUTPUT shaft assembly, this shim ring restores factory-spec endplay and extends service life.

Symptoms of Failure

• Excessive axial play or clunking noise – A worn 0630.000.182 shim ring allows the output shaft to shift, producing audible knocking during gear engagement or deceleration.
• Oil leaks at the output flange seal – Deteriorated clearance from a collapsed shim ring misaligns the 4616203017: OUTPUT FLANGE, causing seal distortion and fluid seepage.
• Premature bearing wear – Incorrect shim thickness leads to uneven load on tapered roller bearings, generating metallic debris in the oil pan.
• Gear slipping under load – Loss of axial preload from a fatigued shim ring reduces clutch pack clamping force, resulting in torque loss during uphill or heavy-haul operation.

Technical Specifications

Compatibility

This shim ring is engineered for the ZF WG 65 Series, including models WG65, WG80, WG100, WG120, WG150, WG180, and WG200. It is also used in select ZF Ecomat 4HP and 5HP transmissions where output shaft shimming is required. Always verify clearance after installation using a dial indicator. For complete rebuilds, inspect the 4616101117: TRANSMISSION HOUSING for wear and replace the 0636011038: HEXAGON SCREW to ensure proper clamping torque on the output flange assembly.
