Overview
The ZF 0730.005.901 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 200 series transmission family. This hardened steel washer functions as a critical load-spreading interface between fastening hardware and transmission housing surfaces, ensuring proper clamping force distribution during assembly. Positioned within the gear train or mounting points of the WG200, this washer prevents galling and maintains axial alignment under high-torque conditions. The SKU 0730.005.901 is manufactured to ZF’s exacting tolerances, making it an essential replacement part for maintaining drivetrain integrity. When paired with the 4460165051 CONSOLE or the 4460368311 CONSOLE, this washer ensures stable mounting of transmission control assemblies.
Symptoms of Failure
- Transmission oil seepage at mounting bolts: A worn or deformed 0730.005.901 washer can no longer maintain a proper seal, allowing lubricant to weep past bolt heads and accumulate on the transmission casing.
- Loose console or bracket vibration: When the washer loses its compressive integrity, the 0636011429 HEXAGON SCREW may back out over time, causing audible rattling or shifting of attached components during gear changes.
- Gear engagement hesitation: A collapsed washer alters the stack-up height in the shift mechanism, leading to delayed or incomplete clutch pack engagement under load.
- Metallic debris in transmission fluid: Advanced washer failure produces fine steel particles that contaminate the hydraulic circuit, accelerating wear on pumps and valve bodies.

Compatibility
This washer is a direct-fit OEM component for the ZF WG200 series transmissions, including models WG200, WG210, and WG180 variants produced after 2005. It is also compatible with certain WG150 and WG160 units that share the same bolt pattern for console and flange mounting. For applications requiring additional sealing, the 0730100365 WASHER provides a copper-crush alternative for high-temperature zones. Always verify stack-up clearance when replacing this part alongside the 4460165051 CONSOLE or 4460368311 CONSOLE.
