Overview
The ZF 0730.008.831 SHIM is a precision-engineered adjustment component designed specifically for the WG 200 series transmission. This OEM genuine shim sits between the bearing assembly and the housing to establish critical axial clearances, ensuring correct gear mesh and load distribution within the planetary gear set. The SKU 0730.008.831 is manufactured to exact ZF tolerances, making it essential for maintaining the structural integrity of the transmission during rebuilds or repairs. Without this shim, the entire gear train can shift out of alignment, leading to premature wear on adjacent components such as the 4460165051: CONSOLE and the 4460368311: CONSOLE.
Symptoms of Failure
- Oil leaks around the bearing housing: A worn or crushed 0730.008.831 shim allows excessive movement, breaking the seal between the housing and the bearing retainer, which results in visible transmission fluid seepage.
- Gear slipping under load: When the axial clearance becomes too large due to shim degradation, the clutch packs cannot engage fully, causing intermittent slipping during acceleration or hill climbs.
- Metallic grinding noises from the transmission: Insufficient shim thickness leads to metal-on-metal contact between the planetary gears and the housing, producing a distinct grinding sound that worsens with RPM.
- Vibration during gear changes: A failed shim disrupts the precise alignment of the output shaft, transmitting vibration through the driveline during shifts.

Compatibility
This shim is a direct fit for the ZF WG 200 series transmission family, including models such as the WG180, WG200, and WG210. It is also used in certain variants of the WG 150 series where the bearing housing dimensions match. The 0730.008.831 is commonly installed alongside the 0636011429: HEXAGON SCREW and the 0730100365: WASHER to secure the bearing assembly. For complete transmission rebuilds, verify compatibility with your specific transmission serial number.
