Overview
The ZF 2093.140.005 HOISTING UNIT is a critical OEM genuine component engineered for the precise lifting and lowering functions within heavy-duty construction machinery transmissions. This unit integrates directly into the power take-off (PTO) assembly of ZF drivetrains, converting hydraulic or mechanical input into controlled vertical motion for winches and crane operations. As a genuine ZF part, the SKU 2093.140.005 ensures exact fitment and factory-specified load tolerances, eliminating the risks associated with aftermarket substitutes. It works in concert with the 2093109029: DIFFERENTIAL to manage torque distribution during hoisting cycles.
Symptoms of Failure
- Erratic hoisting speed or load drift: When the hoisting unit wears, the transmission fails to maintain consistent lifting velocity, causing the load to drift downward unexpectedly during operation.
- Hydraulic oil contamination near the PTO housing: A failing seal within the 2093.140.005 unit allows transmission fluid to mix with hydraulic oil, visible as dark, gritty residue around the housing flange.
- Audible grinding or whining during load engagement: Worn internal gears produce a distinct metallic noise when the hoisting unit engages, particularly under heavy load at low RPM.
- Intermittent gear slipping under load: The unit may disengage momentarily during lifting, causing sudden jerks in the hoist line—a clear sign of internal clutch or spline wear.

Compatibility
This hoisting unit is designed for integration into ZF’s WG-series and ERG-series transmissions commonly used in telescopic handlers, mobile cranes, and excavators. It is a direct fit for the WG180, WG200, and ERG180 models. The unit interfaces with the 2093209094: DIFFERENTIAL and the 2093309078: DIFF.HOUSING to complete the final drive assembly. For optimal performance, always pair the hoisting unit with the 0750117075: TAPER ROLLER BEARING to ensure proper axial load support.

Frequently Asked Questions
Q: Can the 2093.140.005 be used in a ZF WG180 transmission without modification?
A: Yes, this hoisting unit is a direct OEM replacement for WG180, WG200, and ERG180 models. No machining or adapter plates are required.
Q: What is the typical service interval for this hoisting unit?
A: Under normal construction duty, ZF recommends inspection every 1,500 operating hours. Replace the unit if seal leakage or gear backlash exceeds 0.15 mm.
Q: Does this part include the mounting bolts and seals?
A: The 2093.140.005 ships as the complete hoisting unit assembly. For the seal kit, we recommend ordering the 0631100223: SPRING PIN separately if your application requires additional retention hardware.
