Overview
The ZF 0730.304.932 ADJUSTMENT PLATE is a precision-machined OEM genuine component engineered to maintain critical axial clearances within ZF heavy-duty powershift transmissions. This shim-style plate sits between the clutch pack assembly and the transmission housing, ensuring correct preload on rotating elements. The SKU 0730.304.932 is specifically designed to compensate for manufacturing tolerances, preventing premature wear on adjacent components. When installed alongside the 2098117002: HOUSING, this plate guarantees optimal gear engagement depth and hydraulic pressure distribution across the clutch discs.
Symptoms of Failure
- Erratic gear engagement under load – A worn or collapsed adjustment plate allows excessive axial play, causing delayed or harsh shifting when the transmission is under heavy torque.
- Progressive hydraulic fluid seepage – Deterioration of the plate’s seating surface can lead to oil weeping from the joint between the 2098301052: REAR AXLE HOUS. and the main casing.
- Metallic debris in transmission fluid – As the plate wears, microscopic steel particles contaminate the oil, often visible during routine drain intervals.
- Audible knocking from the clutch housing – Excessive clearance causes the clutch pack to shift laterally, producing a distinct metallic rattle during deceleration.

Compatibility
This adjustment plate is primarily utilized in ZF WG180, WG200, and WG210 series powershift transmissions commonly found in construction machinery such as wheel loaders, telehandlers, and graders. It also fits select variants of the ZF 4WG-200 and 6WG-200 torque converter transmissions. For proper installation, ensure the 0636103300: STUD and 0637101164: HEXAGON NUT are torqued to factory specifications to prevent distortion of the plate during reassembly.
