ZF 0730.002.632 WASHER for WG65 | OEM Genuine Part

Genuine ZF WASHER (Part No. 0730.002.632). This part fits: 4 WG 65, 4 WG 65 II(D). Found in: Output. Also referenced as: 0730002632 / 0730.002.632 / 0730 002 632.

Overview

The ZF 0730.002.632 WASHER is a precision-engineered sealing component designed specifically for the WG 65 series transmission. This OEM genuine part functions as a critical load-distribution element between fasteners and housing surfaces, ensuring proper clamping force and preventing fluid migration. Located within the transmission assembly, the washer sits directly against the TRANSMISSION HOUSING, where it creates a reliable seal when paired with mounting hardware. The SKU 0730.002.632 is manufactured to ZF’s exacting tolerances, guaranteeing dimensional stability under high torque and thermal cycling conditions.

Symptoms of Failure

  • Transmission fluid seepage at mounting points – A worn or deformed washer allows oil to escape around bolt heads, leaving visible residue on the housing exterior.
  • Audible clicking or ticking from gear engagement – Loss of washer thickness reduces preload on fasteners, causing slight movement between components during load shifts.
  • Gradual gear engagement delay – Insufficient sealing pressure leads to internal pressure loss, affecting clutch pack actuation timing.
  • Increased vibration at highway speeds – Compromised washer integrity alters the clamping force distribution, allowing micro-movements that transmit as driveline shudder.

Compatibility

This washer is a standard fitment across the ZF WG series of powershift transmissions, including the WG65, WG120, WG180, and WG200 models. It is also used in certain WG210 and WG250 variants where the same bolt pattern and housing interface are employed. The 0730.002.632 washer is frequently replaced alongside the HEXAGON SCREW (M14 thread) and the HEXAGON SCREW (M16 thread) during transmission rebuilds. For applications requiring additional sealing, pair this washer with the HEXAGON SCREW (M18 thread) to ensure proper torque retention.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “No. ZF recommends replacing this washer with a new OEM part (0730.002.632) every time the fastener is removed. The case-hardened steel deforms plastically during initial torque application, and reuse compromises sealing integrity.”
