Overview
The ZF 4108.322.058 SLEEVE is a precision-machined OEM genuine component designed to function as a critical wear surface and alignment guide within the transmission housing assembly. Positioned directly on the main shaft, this sleeve ensures correct spacing and rotational stability for adjacent gear sets and sealing elements. As an integral part of the lubrication and sealing circuit, the 4108.322.058 sleeve prevents metal-on-metal contact and maintains hydraulic pressure integrity. This part is commonly replaced during a major transmission overhaul to restore factory tolerances and eliminate internal play.
Symptoms of Failure
When the ZF 4108.322.058 sleeve wears beyond specification, operators typically encounter these distinct failure modes:
- Oil leaks at the shaft exit point – A worn sleeve allows the shaft seal to lose its interference fit, causing transmission fluid to weep or stream from the bell housing area.
- Gear engagement hesitation or slipping – Excessive radial clearance from a scored sleeve disrupts clutch pack alignment, leading to delayed shifts or power loss under load.
- Metallic debris in the oil pan – As the sleeve surface degrades, fine steel particles contaminate the hydraulic fluid, often visible during routine drain intervals.
- Abnormal whining or grinding noise – Loss of concentricity between the sleeve and the shaft creates a cyclical noise that increases with engine RPM.

Compatibility
This sleeve is engineered for ZF heavy-duty powershift transmissions commonly used in construction machinery. It is a direct fit for the WG180, WG200, and WG210 series. Additionally, it is compatible with the 4WG-180 and 4WG-200 variants found in wheel loaders, dozers, and graders. Always verify the serial number range of your transmission before ordering.
Related Components
During installation of the 4108.322.058 sleeve, it is standard practice to inspect and replace the surrounding assembly components. The sleeve seats inside the 4108101115: HOUSING and mates with the 4108201277: HOUSING. Proper lubrication flow is maintained by the 0501313402: DRAIN VALVE, while the 4108301304: BEARING COVER provides axial retention. For a complete rebuild, the following parts are frequently ordered together:
