Overview
The ZF 0730.000.495 SHIM is a precision-engineered adjustment component designed for the WG 200 Series transmission. This OEM genuine part, identified by SKU 0730.000.495, is installed within the planetary gearset assembly to establish precise axial clearances and preload tolerances. By occupying the space between the bearing race and the housing, this shim ensures that rotating elements maintain correct end-play, preventing metal-to-metal contact under load. Without this critical spacer, the entire gear train would experience excessive movement, leading to accelerated wear and operational instability.
Symptoms of Failure
- Oil leaks around the transmission housing: When the 0730.000.495 shim compresses or deforms beyond specification, the bearing preload is lost, causing seal misalignment and fluid seepage.
- Gear slipping under moderate torque: A worn shim allows the planetary carrier to shift axially, resulting in intermittent power loss during acceleration or hill climbs.
- Abnormal whining or grinding noise from the gearbox: Excessive end-play from a collapsed shim creates uneven gear contact, producing a high-pitched whine that intensifies with speed.
- Vibration through the driveline during deceleration: Backlash caused by shim deterioration transfers shock loads to the output shaft, felt as a shudder in the vehicle chassis.

Compatibility
This shim is specifically engineered for the ZF WG 200 Series transmission family, including models WG180, WG200, and WG210. It is also compatible with certain WG 150 variants that share the same planetary carrier architecture. Always verify the stack height requirement against your transmission’s service manual, as multiple shim thicknesses (0.300 mm to 0.800 mm) are used in the same position. The 0730.000.495 is frequently replaced alongside the 4460165051: CONSOLE and the 4460368311: CONSOLE, which support the bearing housing. Secure the assembly using the 0636011429: HEXAGON SCREW and a new 0730100365: WASHER to ensure proper torque retention.
