ZF 0730.004.673 SHIM | OEM Genuine Part

Overview

The ZF 0730.004.673 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within ZF heavy-duty transmissions. This thin, hardened steel component sits between the transmission housing and bearing assemblies, ensuring proper preload and alignment of rotating elements. The SKU 0730.004.673 is specifically utilized in construction machinery drivelines where vibration resistance and load distribution are paramount. By maintaining exact tolerances, this shim prevents metal-to-metal contact and extends the service life of adjacent components such as the 2094101017 TRANSMISSION HOUSING and the 2094301069 HOUSING.

Symptoms of Failure

• Excessive gear noise and whining – When the 0730.004.673 shim wears or compresses beyond tolerance, axial play increases, causing gear teeth to misalign under load. This generates a distinct high-pitched whine during acceleration or deceleration.
• Intermittent gear slipping under heavy load – A worn shim reduces clutch pack clamping force, leading to momentary power loss when excavating or lifting. Operators often report this as a “soft shift” sensation.
• Oil seepage at housing mating surfaces – Degraded shim thickness can distort the seal between the 2094298054 HOUSING and the transmission case, allowing hydraulic fluid to weep past gaskets. This is frequently misdiagnosed as a simple gasket failure.
• Premature bearing failure – Without proper shim support, bearings experience uneven loading, leading to brinelling and eventual seizure. This often accompanies a gradual increase in operating temperature.

Technical Specifications

Compatibility

This shim is engineered for ZF WG-series powershift transmissions commonly found in wheel loaders, graders, and telehandlers. It is directly compatible with the following models: WG180, WG200, WG211, and WG310. The 0730.004.673 also fits select ErgoPower and Ecolife variants used in construction machinery. For proper installation, always pair this shim with a new 0636302008 SCREW PLUG to ensure thread sealing and prevent fluid bypass.
