Overview
The ZF 0730.006.507 WASHER is an OEM genuine precision shim designed specifically for the WG 65 series transmission. This hardened steel washer sits between the transmission housing and the planetary carrier assembly, providing critical axial clearance control and load distribution. As part number 0730.006.507, it ensures proper preload on bearing surfaces within the gear train, preventing metal-to-metal contact during high-torque operation. When installed alongside the 4616101111: TRANSMISSION HOUSING, this washer maintains the exact spacing required for optimal gear mesh alignment.
Symptoms of Failure
- Transmission oil seepage at housing joints — A worn 0730.006.507 washer allows the 4616301304: HOUSING to shift, breaking the seal and causing slow fluid loss.
- Gear slipping under load — When the washer thickness degrades, axial play increases, causing planetary gears to lose engagement during heavy torque demands.
- Metallic grinding noise from the bell housing — Insufficient washer height lets rotating components contact the 4616301309: HOUSING, producing audible wear sounds.
- Vibration during gear shifts — Uneven washer compression creates misalignment that transmits through the 0636011118: HEXAGON SCREW fasteners, causing driveline shudder.

Compatibility
This washer is engineered for the ZF WG 65 series, but it also fits select models in the WG180 and WG200 families where similar axial spacing requirements exist. It is a direct replacement for transmissions using the 0636011038: HEXAGON SCREW and 0636016015: HEXAGON SCREW in the housing assembly. Always verify compatibility with your specific transmission serial number before installation.
