Overview
The ZF 0730.005.322 SHIM is a precision-engineered adjustment component designed for the WG65 series of heavy-duty transmissions. This OEM genuine part is critical for establishing the correct axial clearance and preload within the planetary gear set assembly. Installed between the TRANSMISSION HOUSING and the bearing race, the SKU 0730.005.322 compensates for manufacturing tolerances, ensuring optimal gear mesh alignment and load distribution. By maintaining exact spacing, this shim prevents internal component contact and reduces vibration, directly extending the service life of the entire drivetrain.
Symptoms of Failure
- Excessive end-play or axial movement in the output shaft: When the 0730.005.322 shim wears or compresses beyond tolerance, you will notice a distinct clunking sensation during gear engagement or when shifting between forward and reverse.
- Persistent low-frequency gear whine under load: A worn shim allows the planetary gears to drift out of their ideal contact pattern, producing a constant, droning noise that intensifies with torque application.
- Premature bearing failure and metallic debris in the oil pan: Incorrect clearance forces the tapered roller bearings to operate outside their designed preload, generating fine metallic particles that contaminate the transmission fluid.
- Intermittent gear slipping under heavy acceleration: Loss of precise spacing can cause the clutch packs to engage inconsistently, leading to momentary power loss during uphill hauls or loaded starts.

Compatibility
This shim is specifically engineered for the WG65 transmission series. Based on its dimensional profile and application within the planetary carrier assembly, it is also compatible with the following ZF models that share the same housing architecture: WG180, WG200, WG210, and WG250. Always verify the existing shim stack thickness during rebuild. The 0730.005.322 is installed directly against the HOUSING (part 4616301307) or the alternative HOUSING (part 4616301309), and is secured using the HEXAGON SCREW (0636011118) to ensure zero movement during operation.
