ZF 0630.005.011 WASHER | OEM Genuine Part

Overview

The ZF 0630.005.011 WASHER is a precision-engineered OEM genuine component designed to function as a critical load-spreading and axial positioning element within the clutch pack and planetary gear assemblies of heavy-duty construction machinery transmissions. This hardened steel washer ensures correct clearance between rotating and stationary components, preventing metal-on-metal contact that leads to premature wear. The SKU 0630.005.011 is specifically calibrated to maintain the exacting tolerances required for ZF power shift transmissions, directly influencing shift quality and torque transfer efficiency. It sits between the sun gear and the housing, often paired with the 4699101093: HOUSING and the 4699301175: HOUSING to form a sealed, lubricated cavity.

Symptoms of Failure

• Transmission oil leaks near the bell housing: A worn 0630.005.011 washer can allow axial play, compromising the seal between the 4699301041: COVER and the shaft, leading to external fluid seepage.
• Gear slipping under load: When the washer thickness degrades, clutch pack clearance increases, causing delayed engagement and power loss during excavation or grading operations.
• Metallic debris in the oil pan: Spalling of the washer surface introduces fine steel particles into the hydraulic circuit, which can clog the 0634303936: O-RING sealing points and accelerate bearing failure.
• Abnormal whining or grinding noise: Insufficient washer support allows planetary gears to walk axially, generating a distinct high-pitched whine during deceleration.

Technical Specifications

Compatibility

This washer is a standard component in the ZF WG180, WG200, and WG210 series power shift transmissions commonly found in wheel loaders, graders, and telehandlers. It is also used in the 4WG-200 and 6WG-200 variants where it supports the input shaft assembly. Always verify fitment against your transmission serial number, as the washer works in conjunction with the 0630513203: SNAP RING and the 0750110302: SHAFT SEAL to secure the bearing stack.
