Overview
The ZF 2098.140.014 HOISTING UNIT is a critical OEM genuine component engineered for demanding lifting and material handling applications within construction machinery drivelines. This precision-machined assembly sits directly within the transmission’s power take-off (PTO) system, converting engine torque into controlled hydraulic or mechanical lift force for crane winches, boom cylinders, and dump mechanisms. As a factory-specified replacement, the SKU 2098.140.014 ensures exact fitment and load-bearing integrity, preventing premature wear in high-cycle environments. For optimal drivetrain balance, this hoisting unit is frequently paired with the 2098109041: DIFFERENTIAL to distribute torque evenly across axles during simultaneous lifting and driving operations.
Symptoms of Failure
- Intermittent hoist slippage under load: When the 2098.140.014 unit’s internal clutch pack or hydraulic seals degrade, operators report sudden load drop or hesitation during lifting—a classic sign of worn friction surfaces.
- External oil seepage near the PTO housing: Degraded shaft seals or housing cracks allow transmission fluid to weep, leaving visible drips on the bell housing. This often coincides with a burnt smell from overheated oil.
- Grinding or whining noise during engagement: Worn bearings or misaligned gears inside the hoisting unit produce metallic sounds, especially when shifting from neutral to lift mode. This symptom accelerates if the 0635332034: BALL BEARING is also failing.
- Delayed or jerky lift response: Hydraulic pressure loss from internal leakage causes a lag between lever input and actual movement, often accompanied by vibration in the control valve.

Compatibility
This hoisting unit is designed for integration with ZF’s WG180, WG200, and WG211 series transmissions commonly used in wheel loaders, telehandlers, and mobile cranes. It is also compatible with the 4WG-180 and 4WG-200 variants found in older Liebherr and Volvo construction equipment. For driveline completeness, ensure the 2098110053: P.T.O. SHAFT and 2098310099: P.T.O. SHAFT are inspected for spline wear when replacing the hoisting unit, as mismatched shafts can cause premature failure.
