Overview
The ZF 0730.112.613 SHIM is a precision-engineered OEM genuine component designed for critical axial clearance adjustment within ZF heavy-duty transmissions. This shim, identified by SKU 0730.112.613, is installed between the differential housing and the crown wheel assembly to establish the correct preload and backlash tolerances. Without this exact shim, gear mesh patterns become erratic, leading to accelerated wear on adjacent components. In construction machinery transmissions, this part ensures that the 2099109002: DIFFERENTIAL and the 2099364014: CROWN WHEEL maintain their factory-specified operating clearances under extreme load conditions.
Symptoms of Failure
When the ZF 0730.112.613 shim wears or deforms, operators typically notice these specific failure indicators:
- Excessive differential housing noise during turns – A grinding or whining sound from the 2098309010: DIFFERENTIAL HOUSING indicates lost shim thickness.
- Intermittent gear slipping under load – Backlash increases as the shim compresses, causing the crown wheel to momentarily lose contact with the pinion.
- Metallic debris in transmission oil – Worn shim material contaminates the lubricant, often visible during routine drain intervals.
- Vibration at specific RPM ranges – Incorrect shim height creates harmonic resonance in the driveline, particularly in WG-series transmissions.

Compatibility
This shim is specifically engineered for ZF heavy-duty transmissions used in construction machinery. It is a direct fit for the following transmission models:
- ZF WG180 – All series (WG180/181/182)
- ZF WG200 – All series (WG200/201/202)
- ZF WG210 – Select configurations with differential lock
- ZF 4WG-200 – Powershift variants
When replacing this shim, always inspect the mating surfaces of the 2099209001: DIFFERENTIAL and the crown wheel for scoring. The shim works in concert with the 2098309010: DIFFERENTIAL HOUSING to maintain proper gear alignment. For complete rebuilds, consider replacing the 12883200682: THRUST WASHER and 0635332059: BALL BEARING simultaneously to ensure uniform wear patterns.
