Overview
The ZF 0730.102.459 SHIM is a precision-engineered adjustment component designed for the WG series of heavy-duty powershift transmissions. This OEM genuine part is critical for establishing the correct axial clearance and preload within the transmission’s rotating assembly. Installed between the TRANSMISSION HOUSING and the bearing race, the shim compensates for manufacturing tolerances, ensuring that gear meshing and clutch pack engagement remain within factory specifications. The SKU 0730.102.459 is a direct replacement part, guaranteeing a perfect fit and long service life in ZF drivelines.
Symptoms of Failure
- Excessive axial end-play in the main shaft: A worn or incorrect shim (0730.102.459) allows the shaft to move beyond its tolerance, causing a noticeable clunking noise during gear changes.
- Premature bearing failure due to improper preload: If the shim thickness degrades or is incorrectly selected, bearings lose their required preload, leading to overheating and metallic debris in the oil.
- Intermittent gear slipping under load: Incorrect clearance from a failing shim can prevent clutch packs from fully engaging, resulting in power loss during heavy operation.
- Oil leaks from the housing interface: A collapsed shim can distort the housing seal surface, causing fluid to weep past the O-RING and other gaskets.

Compatibility
This shim is a standard component across the ZF WG family of transmissions. It is specifically validated for use in the WG 65 Series, WG 150 Series, WG 180 Series, WG 200 Series, and WG 201 Series. It is typically installed during a rebuild or when replacing the TRANSMISSION HOUSING. Always verify the required shim thickness using the factory clearance measurement procedure. The shim is secured in place using HEXAGON SCREW (0636011038) and HEXAGON SCREW (0636011118) fasteners, with the assembly sealed by a HEXAGON SCREW (0636016015) plug.
