Overview
The ZF 0730.005.266 SHIM is a precision-engineered adjustment component designed specifically for the WG 200 series transmission. This OEM genuine part functions as a critical spacer within the planetary gearset assembly, controlling axial play and ensuring correct gear mesh alignment. The shim sits between the AXLE DRIVE HOUSING and the output shaft components, providing the exact clearance required for optimal load distribution. By maintaining proper end-play tolerances, the 0730.005.266 prevents premature wear on adjacent bearings and housings. This SKU is manufactured to ZF’s original factory specifications, guaranteeing a direct fit and reliable performance in demanding industrial applications.
Symptoms of Failure
- Excessive axial play in the output shaft – When the 0730.005.266 shim wears or compresses beyond tolerance, you may notice noticeable end-float movement in the transmission output flange, leading to gear misalignment and vibration under load.
- Oil leaks from the axle drive housing seal – A worn shim alters the position of rotating assemblies, causing the SHAFT SEAL to lose its contact pattern, resulting in fluid seepage around the housing joint.
- Abnormal bearing noise during deceleration – Incorrect shim thickness places uneven stress on the TAPER ROLLER BEARING and TAPERED ROLLER BEARING, producing a distinct rumbling or grinding sound when the vehicle coasts.
- Intermittent gear slipping under heavy torque – As the shim degrades, the HOUSING alignment shifts, reducing clutch pack engagement pressure and causing momentary power loss during acceleration.

Compatibility
This shim is primarily designed for the ZF WG 200 series transmissions, including the WG180, WG200, and WG210 models used in off-highway vehicles, construction equipment, and agricultural machinery. It is also compatible with certain WG 150 variants that share the same planetary carrier assembly. The 0730.005.266 is typically installed during rebuilds of the output section where the AXLE DRIVE HOUSING interfaces with the differential. Always verify the shim stack height against the factory service manual, as multiple shims (including WASHER part 0730161317) may be combined to achieve precise clearance.
