ZF 0730.008.790 SHIM | OEM Genuine Part

Overview

The ZF 0730.008.790 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearance within ZF powershift transmissions used in construction machinery. This thin, hardened steel shim sits between the transmission housing and bearing assemblies, compensating for manufacturing tolerances and ensuring correct preload on rotating components. The SKU 0730.008.790 is essential for maintaining gear alignment and preventing excessive end-play that can lead to premature wear. When rebuilding a transmission, this shim is often replaced alongside the 2094101012: TRANSMISSION HOUSING to restore factory-specified clearances.

Symptoms of Failure

• Transmission gear slipping under load — A worn or collapsed shim allows the shaft to shift axially, causing incomplete gear engagement and power loss during operation.
• Oil leaks at housing mating surfaces — Incorrect shim thickness can distort the 2094301036: HOUSING seal surface, leading to fluid seepage around the joint.
• Metallic grinding noise from the gear train — Excessive axial play from a degraded shim permits gear teeth to contact housing walls or adjacent components, producing a distinct grinding sound.
• Vibration during gear shifts — Loss of proper shim preload causes bearing instability, transmitting vibration through the driveline during clutch engagement.

Technical Specifications

Compatibility

This shim is primarily used in ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, graders, and heavy forklifts. It also fits select ZF 4WG-200 and 6WG-200 models where axial shimming of the input shaft is required. Always verify clearance requirements when replacing the 2094298057: HOUSING or 2094301071: COVER, as these components directly affect shim stack height.
