ZF 0730.005.555 SHIM for WG201 | OEM Genuine Part

Overview

The ZF 0730.005.555 SHIM is a precision-engineered spacer component designed specifically for the WG 201 series transmission. This OEM genuine part plays a critical role in maintaining correct axial clearance and preload within the gear train assembly. Installed between the TRANSMISSION HOUSING and adjacent bearing surfaces, the shim compensates for manufacturing tolerances, ensuring optimal gear mesh alignment and load distribution. The SKU 0730.005.555 is manufactured to ZF’s exacting specifications, guaranteeing a perfect fit and long service life in heavy-duty industrial applications.

Symptoms of Failure

• Excessive axial play in the output shaft — When the 0730.005.555 shim wears or compresses beyond tolerance, noticeable end float develops in the transmission shaft, leading to vibration during operation.
• Oil leaks around the housing interface — A degraded shim can cause misalignment between the TRANSMISSION HOUSING and mating components, compromising seal integrity and resulting in fluid seepage.
• Gear engagement noise under load — Worn shim thickness alters gear backlash, producing a distinct whining or clattering sound during acceleration or deceleration.
• Premature bearing failure — Incorrect shim height places abnormal stress on tapered roller bearings, accelerating wear and reducing overall transmission life.

Technical Specifications

Compatibility

This shim is primarily used in ZF WG 201 series transmissions, including models WG180, WG200, WG201, and WG210. It is also compatible with select variants of the WG 211 and WG 220 series where the same bearing preload specification applies. Always verify the existing shim thickness before replacement, as selective fit shims are matched to individual transmission builds. The 0730.005.555 works in conjunction with the THREADED BUSH and SCREW PLUG to secure the bearing stack in the housing bore.
