Overview
The ZF 2093.240.001 LIFTING SHAFT is a precision-engineered component designed to manage the vertical movement of the differential carrier within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part, identified by SKU 2093.240.001, sits inside the axle housing assembly and acts as the pivot point for the lifting mechanism, enabling smooth engagement and disengagement of the differential lock. When paired with the 2093109002: DIFFERENTIAL and the 2093209095: DIFFERENTIAL, this shaft ensures reliable torque distribution under heavy loads. Constructed from hardened alloy steel, it resists wear from constant articulation, making it a critical link in the drivetrain’s load-bearing chain.
Symptoms of Failure
- Erratic differential lock engagement: A worn lifting shaft causes the differential to engage or disengage with a noticeable delay or clunk, often accompanied by grinding noises during low-speed turns.
- Oil leaks around the axle housing: When the shaft’s sealing surface becomes scored, transmission fluid seeps past the 0750117075: TAPER ROLLER BEARING, leaving visible drips under the vehicle after parking.
- Increased driveline vibration: A bent or fatigued lifting shaft creates harmonic vibrations at highway speeds, felt through the floorboard and steering wheel, indicating misalignment with the 2093309071: DIFF.HOUSING.
- Intermittent power loss to wheels: As the shaft fails to maintain proper lift height, torque delivery becomes inconsistent, causing the vehicle to hesitate under load or on inclines.

Compatibility
This lifting shaft is engineered specifically for ZF heavy-duty transmissions in the WG series. It is a direct fit for the following models: WG100, WG130, and WG131. These transmissions are commonly found in agricultural tractors, construction loaders, and municipal utility vehicles. The shaft also interfaces with the 0631100223: SPRING PIN for secure retention and the 0730300820: THRUST WASHER for axial load distribution. For vehicles using the 4482360002: AXLE BEVEL GEAR or 2097309085: DIFFERENTIAL AXLE, verify the housing bore dimensions to ensure proper alignment with the 5838300811: THRUST WASHER and 4482360001: DIFFERENTIAL BEVEL GEAR.

Frequently Asked Questions
Q: Can I install the ZF 2093.240.001 lifting shaft without replacing the taper roller bearing?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously, as a worn bearing can cause premature shaft wear and misalignment within the diff housing.
Q: How do I confirm this shaft fits my WG130 transmission?
A: Measure the existing shaft length and diameter. The 2093.240.001 is 245 mm long with a 32 mm diameter. Also inspect the 2093309071: DIFF.HOUSING for any cracks or deformation before installation.
Q: What torque specification should I use for the retaining spring pin?
A: The 0631100223: SPRING PIN should be driven flush with the housing surface using a 6 mm punch; no torque wrench is required, but ensure the pin is fully seated to prevent shaft movement.
