Overview
The ZF 0730.003.460 SHIM is a precision-engineered adjustment component designed specifically for the WG150 series transmission. This OEM genuine shim plays a critical role in establishing the correct axial clearance between rotating assemblies and stationary housings within the gear train. By maintaining precise end-play tolerances, the 0730.003.460 ensures optimal load distribution across bearings and gears, directly influencing shift quality and overall drivetrain longevity. As a factory-specification part, it guarantees exact fitment and material integrity for professional rebuilds and maintenance operations.
Symptoms of Failure
- Excessive axial play or gear rattle: When the 0730.003.460 shim wears or compresses beyond tolerance, noticeable end-play develops in the main shaft, producing a distinct rattling noise during deceleration or idle.
- Premature bearing failure: A degraded shim allows improper preload, leading to uneven bearing wear. Technicians often detect this through increased operating noise or metallic debris in the oil pan.
- Oil leaks near the transmission housing interface: Incorrect shim thickness can distort the seal surface between the TRANSMISSION HOUSING and the TRANSMISSION HOUSING, causing fluid seepage under load.
- Intermittent gear slipping under torque: As axial clearance increases, gear engagement depth decreases, resulting in momentary power loss during acceleration or hill climbing.

Compatibility
This shim is engineered for the ZF WG150 series transmission family. Based on its dimensional profile and application, it is also compatible with the WG180 and WG200 models that share the same planetary carrier and shaft assembly architecture. Always verify the existing shim stack thickness before installation. For complete transmission assembly, ensure the TYPE PLATE is correctly affixed for future identification, and secure all components using the GROOVED STUD at the designated mounting points.
