Overview
The ZF 0730.101.273 WASHER is a precision-engineered OEM genuine component designed for the WG 200 series powershift transmissions. This hardened steel washer functions as a critical thrust or shim element within the planetary gearset assembly, ensuring correct axial clearance and load distribution between rotating components. Installed directly against the 4460115043 HOUSING, this washer prevents metal-to-metal contact and maintains proper gear alignment under high-torque conditions. The SKU 0730.101.273 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit without modification.
Symptoms of Failure
- Transmission oil leaks at the housing interface: A worn 0730.101.273 washer allows excessive axial play, compromising the seal between the 4469315012 AXLE DRIVE HOUSING and adjacent components, leading to external fluid seepage.
- Gear slipping under load: Deterioration of this thrust washer reduces clamping force on the planetary carrier, causing intermittent power loss during acceleration or hill climbs.
- Metallic grinding noise from the transmission: When the washer thickness degrades, the 0750117406 TAPER ROLLER BEARING and 0750117802 TAPERED ROLLER BEARING can contact the housing directly, producing a distinct grinding sound during gear shifts.
- Increased end float in the output shaft: Measurable axial movement exceeding 0.5mm indicates the washer has compressed beyond its service limit, requiring immediate replacement.

Compatibility
This washer is specifically engineered for the ZF WG 200 series transmission family, including models WG180, WG200, and WG210. It is also used in certain WG 150 variants with planetary gear reduction. The 0730.101.273 interfaces directly with the 4460115043 HOUSING and the 4469315012 AXLE DRIVE HOUSING. For applications requiring the 0750117406 TAPER ROLLER BEARING or 0750117802 TAPERED ROLLER BEARING, this washer must be inspected simultaneously to prevent premature bearing failure.
