ZF 0730.150.385 SHIM | OEM Genuine Part

Overview

The ZF 0730.150.385 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within ZF heavy-duty transmissions. This thin, hardened steel spacer sits between the transmission housing and bearing assemblies, ensuring proper preload and alignment of rotating shafts. By maintaining exact tolerances, the SKU 0730.150.385 prevents internal gear clash and compensates for manufacturing variances. It is commonly installed during rebuilds of construction machinery transmissions, where even micron-level deviations can lead to premature wear. This shim works in concert with the 2094101012: TRANSMISSION HOUSING to secure the gear train’s lateral position.

Symptoms of Failure

• Excessive axial play in the input shaft – When the shim compresses or wears, you may detect a noticeable “clunk” when engaging the clutch, indicating lost preload.
• Gear slipping under load – A worn 0730.150.385 allows the main shaft to drift, causing intermittent disengagement of gear teeth, especially in WG-series transmissions.
• Metallic grinding noise from the bell housing – Insufficient shim thickness permits gear faces to contact the 2094301036: HOUSING, producing a distinct high-pitched grind during acceleration.
• Oil contamination with fine metal particles – As the shim degrades, it sheds material into the lubrication system, often visible during oil changes as silver glitter.

Technical Specifications

Compatibility

This shim is engineered for ZF’s WG-series powershift transmissions commonly used in construction machinery. It fits the following models: WG180, WG200, WG210, and WG250. It is also applicable to certain ZF 4WG-310 and 6WG-200 variants. The part interfaces directly with the 2094298057: HOUSING and the 2094301071: COVER to form the bearing retention assembly. Always verify your transmission serial number before ordering.
