Overview
The ZF 0630.100.277 WASHER is an OEM genuine precision shim component engineered for critical load distribution within heavy-duty construction machinery transmissions. This hardened steel washer sits between rotating assemblies and stationary housings, specifically in the planetary gear sets of ZF power shift transmissions. The SKU 0630.100.277 ensures exact axial clearance control, preventing metal-to-metal contact between the 4108101112: HOUSING and the 4108201177: HOUSING during high-torque operation. As a factory-specified component, it maintains the precise end-play tolerances required for long-term transmission reliability.
Symptoms of Failure
- Transmission oil leaks at housing joints – When the 0630.100.277 washer compresses or fractures, the gap between the 4108301304: BEARING COVER and adjacent housing widens, allowing pressurized ATF to escape.
- Gear slipping under load – Worn washers reduce clamping force on planetary carriers, causing intermittent clutch pack disengagement during excavation or grading operations.
- Metallic grinding noise from transmission – A collapsed washer permits the 0636302056: SCREW PLUG to contact rotating gears, producing audible chatter at low RPM.
- Vibration during gear shifts – Uneven washer wear creates axial play that destabilizes the input shaft, leading to harsh engagement in construction machinery transmissions.

Compatibility
This washer is a direct fit for ZF WG180, WG200, and WG211 series transmissions commonly used in wheel loaders, excavators, and telehandlers. It also applies to ZF 4WG-180, 4WG-200, and 4WG-211 power shift models. The 0630.100.277 is installed between the 4108102042: INPUT assembly and the 4108302099: PLANET CARRIER to maintain proper preload. Always verify your transmission serial number before ordering.
