Overview
The ZF 0730.111.772 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 200 Series heavy-duty transmission. This hardened steel shim sits between the planetary gear set and the output shaft housing, ensuring correct axial clearance and load distribution during high-torque operations. As a critical spacer within the WG200 assembly, the SKU 0730.111.772 maintains the exact preload required for the adjacent 0750117406: TAPER ROLLER BEARING and the 0750117802: TAPERED ROLLER BEARING, preventing metal-to-metal contact that would otherwise lead to premature gear wear.
Symptoms of Failure
- Transmission oil leaks at the rear housing interface: When the 0730.111.772 washer compresses or cracks, the seal between the 4460115043: HOUSING and the 4469315012: AXLE DRIVE HOUSING is compromised, allowing ATF to seep past the shaft seal.
- Gear slipping under load in forward gears: A worn washer reduces the preload on the tapered roller bearings, causing axial play that leads to intermittent gear disengagement during acceleration.
- Metallic grinding noise from the transmission sump: As the washer loses its original thickness, the planetary carrier begins to contact the housing, producing a distinct low-frequency grinding sound.
- Vibration through the driveline at highway speeds: Incorrect shim height from a deformed 0730.111.772 washer creates rotational imbalance that transfers directly to the axle drive housing.

Compatibility
This OEM genuine washer is engineered for the ZF WG 200 Series transmission family. Based on its dimensional profile and application within the planetary output section, the 0730.111.772 is compatible with the following ZF models: WG180, WG200, WG210, and WG220. It is also used in select ZF Ecomat 4HP and 5HP variants that share the WG200 output shaft architecture. Always verify your transmission serial number against the ZF parts catalog before ordering.
