Overview
The ZF 2095.240.001 LIFTING SHAFT (SKU: 2095.240.001) is a precision-machined OEM genuine component designed for the internal gear train of ZF WG-series transmissions. This shaft acts as the primary actuation pivot within the differential housing assembly, transferring rotational force from the shift mechanism to the axle bevel gear set. It sits directly within the DIFF.HOUSING and interfaces with the DIFFERENTIAL unit to ensure smooth torque distribution. Manufactured to ZF’s original tolerances, this lifting shaft guarantees precise gear engagement and long service life in heavy-duty industrial applications.
Symptoms of Failure
- Erratic gear engagement or “gear slipping” under load: A worn lifting shaft can cause the differential to misalign, leading to intermittent power loss during operation.
- Metallic grinding noise from the transmission housing: Excessive play in the shaft allows the TAPER ROLLER BEARING to chatter against the housing, producing a distinct scraping sound.
- Oil seepage around the shaft seal area: Surface wear on the lifting shaft compromises the seal lip, allowing transmission fluid to leak past the DIFFERENTIAL interface.
- Increased vibration during low-speed maneuvering: A bent or fatigued shaft creates imbalance that resonates through the driveline, particularly when turning.

Compatibility
This lifting shaft is engineered for the ZF WG100, WG130, and WG131 transmission series. It is also compatible with select WG180 and WG200 variants that share the same differential housing geometry. Always verify fitment by cross-referencing your existing part number with the DIFFERENTIAL AXLE assembly. For mixed-model rebuilds, consult the ZF service manual to confirm shaft-to-bearing clearance.
