Overview
The ZF 0730.161.451 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 200 Series transmission. This hardened steel washer functions as a critical load-spreading interface between rotating assemblies and stationary housings within the gearbox. Installed primarily in the planetary gear set or output shaft area, the SKU 0730.161.451 ensures correct axial clearance and prevents metal-on-metal contact under high torque conditions. When paired with the 4460115043: HOUSING, this washer maintains proper alignment and distributes clamping forces evenly across mating surfaces.
Symptoms of Failure
- Transmission oil leaks at the output flange: A worn 0730.161.451 washer can allow the 4469315012: AXLE DRIVE HOUSING to shift, breaking the seal and causing fluid seepage.
- Gear slipping under load: Excessive washer wear reduces preload on the 0750117406: TAPER ROLLER BEARING, leading to axial play and intermittent power loss.
- Metallic grinding noises during shifting: A collapsed washer allows the 0750117802: TAPERED ROLLER BEARING to contact the housing directly, generating debris and audible wear.
- Vibration in neutral or drive: Uneven washer thickness causes bearing misalignment, transmitting vibration through the driveline.

Compatibility
This genuine ZF washer is engineered for the WG 200 Series transmission family, including models WG180, WG200, and WG210. It is also used in select ZF off-highway and marine gearboxes that share the same planetary carrier design. Always verify fitment by cross-referencing your transmission serial number with the 0730.161.451 SKU. For related sealing components, consider the 0734319337: SHAFT SEAL which is often replaced concurrently.
