Overview
The ZF 0730.111.766 WASHER is a precision-engineered thrust washer designed for the WG 200 series powershift transmissions. This OEM genuine component sits between the rotating gear sets and the stationary 4460115043: HOUSING, providing a critical wear surface that maintains axial clearance and absorbs thrust loads during gear changes. The SKU 0730.111.766 ensures exact fitment and material hardness to prevent premature fretting in high-torque applications. When paired with the 4469315012: AXLE DRIVE HOUSING, this washer stabilizes the planetary gear assembly, directly influencing shift quality and drivetrain longevity.
Symptoms of Failure
- Transmission oil leaks at the housing interface: A worn 0730.111.766 washer reduces clamping force, allowing ATF to seep past the HOUSING seal surface.
- Intermittent gear slipping under load: Excessive axial play from a flattened washer causes the clutch packs to lose engagement pressure, particularly in 3rd and 4th gears.
- Metallic debris in the oil pan: As the washer surface erodes, fine steel particles contaminate the fluid, often misdiagnosed as bearing failure.
- Audible whining or knocking from the transmission: Thrust washer wear allows the 0750117406: TAPER ROLLER BEARING to shift out of its race, creating cyclic noise during acceleration.

Compatibility
This washer is a direct replacement for the following ZF transmission models: WG180, WG200, WG210, and WG220 series. It is specifically calibrated for the WG200 planetary carrier assembly where it interfaces with the 0750117802: TAPERED ROLLER BEARING on the output shaft. Always verify the axial clearance specification (0.10–0.25 mm) when installing this washer alongside the AXLE DRIVE HOUSING to avoid preload errors.
