Overview
The ZF 0730.111.755 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 element within the planetary gearset assembly, ensuring correct axial clearance between rotating components. Installed directly against the 4460115043: HOUSING, it prevents metal-on-metal contact that would otherwise accelerate wear. The SKU 0730.111.755 is manufactured to ZF’s exacting tolerances, guaranteeing a perfect fit and long service life in heavy-duty industrial applications.
Symptoms of Failure
- Transmission oil leaks at the axle drive interface: A worn 0730.111.755 washer can cause misalignment, leading to seal failure and fluid seepage around the 4469315012: AXLE DRIVE HOUSING.
- Gear slipping under load: When this washer loses its original thickness, axial play increases, causing intermittent gear disengagement during torque transfer.
- Metallic grinding noise from the planetary section: Excessive clearance forces the 0750117406: TAPER ROLLER BEARING and 0750117802: TAPERED ROLLER BEARING to operate outside their designed preload range.
- Vibration during shifting: A collapsed washer creates uneven load distribution, transmitting harsh vibrations through the driveline.

Compatibility
This washer is a direct-fit component for the ZF WG 200 Series transmissions, including models WG180, WG200, and WG210. It is also used in certain WG 150 variants with planetary reduction stages. Always verify the part number 0730.111.755 against your transmission’s parts manual, as similar washers like the 0730161317: WASHER or 0730161451: WASHER serve different axial positions within the same assembly.
