ZF 0730.108.403 SHIM | OEM Genuine Part

Overview

The ZF 0730.108.403 SHIM is a precision-engineered spacer component designed for critical axial clearance adjustment within heavy-duty ZF powershift transmissions. This OEM genuine part, identified by SKU 0730.108.403, sits between the differential housing and bearing assemblies to maintain exact preload tolerances. By controlling end-play in the gear train, this shim prevents excessive movement that leads to premature wear on adjacent components. It is commonly used in construction machinery transmissions such as the WG180 and WG200 series, where it works in concert with the 5838109007: DIFFERENTIAL to ensure proper gear mesh alignment.

Symptoms of Failure

• Transmission whining noise under load: A worn or collapsed shim allows the differential assembly to shift, causing gear teeth to misalign and produce a high-pitched whine during operation.
• Intermittent gear slippage in forward gears: When axial clearance exceeds specifications due to shim degradation, clutch packs lose proper engagement pressure, resulting in erratic power delivery.
• Metal debris in transmission fluid: A failing shim that fractures or wears thin can shed metallic particles into the oil system, often detected during routine filter inspections.
• Vibration at the drive axle: Excessive end-play from a worn shim transfers vibration through the 2095209019: DIFFERENTIAL and into the final drive, noticeable at low speeds.

Technical Specifications

Compatibility

This shim is engineered for ZF powershift transmissions commonly found in construction machinery, including the WG180, WG200, and WG250 series. It is also compatible with certain 4WG-200 and 6WG-200 variants used in wheel loaders and graders. When replacing this part, always inspect the 0750117075: TAPER ROLLER BEARING for scoring, as bearing wear often accompanies shim failure. Additionally, verify the condition of the 0631329086: SPRING PIN that secures the differential housing, as a loose pin can accelerate shim deterioration.
