ZF 0730.108.409 SHIM | OEM Genuine Part

Overview

The ZF 0730.108.409 SHIM is a precision-engineered OEM genuine spacer component designed to maintain critical axial clearances within ZF heavy-duty transmissions. This shim, identified by SKU 0730.108.409, is positioned between the differential housing and bearing assemblies to preload gear sets and eliminate unwanted end-play. In construction machinery applications, this thin but vital part ensures that the 5838109007: DIFFERENTIAL remains correctly aligned under extreme torque loads. Without the correct shim thickness, the entire gear train can shift, leading to accelerated wear on surrounding components.

Symptoms of Failure

When the ZF 0730.108.409 shim wears or compresses beyond tolerance, operators will notice distinct operational issues. Excessive differential housing end-play is the most common symptom, often felt as a clunking noise when shifting between forward and reverse. Premature bearing failure occurs as the 0750117075: TAPER ROLLER BEARING loses its preload, generating heat and metallic debris. Intermittent gear slippage under load may also appear, particularly in WG-series transmissions. Finally, oil contamination from metal particles can be detected during routine fluid analysis, indicating the shim has worn through its hardened surface layer.

Technical Specifications

Compatibility

This shim is specifically engineered for ZF powershift transmissions commonly found in construction loaders and graders. Primary compatible models include the ZF WG180, WG200, and WG210 series. It also fits select ZF 4WG-200 and 6WG-200 variants used in articulated dump trucks. The 0730.108.409 shim is often replaced alongside the 2095209019: DIFFERENTIAL assembly and the 0631329086: SPRING PIN that secures the differential cross shaft. Always measure the existing clearance before selecting this shim, as multiple thicknesses are available for precise adjustment.
