Overview
The ZF 4642.154.067 POWER TAKE-OFF is a critical OEM genuine component engineered specifically for the WG 150 Series transmission. This unit transfers engine torque to auxiliary hydraulic systems, such as pumps for dump trucks, concrete mixers, or refuse vehicles. As a factory-sourced part, the SKU 4642.154.067 ensures precise gear engagement and seamless integration within the transmission housing assembly. It mounts directly to the PTO aperture, converting rotational energy into hydraulic power without compromising driveline efficiency. For maximum reliability, this unit works in tandem with the 4642101109: TRANSMISSION HOUSING and the 4642301205: TRANSMISSION HOUSING to maintain structural integrity under heavy loads.
Symptoms of Failure
- Hydraulic pressure drop or intermittent power loss: Worn internal gears or bearings in the 4642.154.067 can cause inconsistent pump output, leading to sluggish hydraulic functions during operation.
- Audible grinding or whining noise from the PTO housing: Deteriorated gear teeth or shaft misalignment produce distinct metallic sounds, especially under load, signaling imminent failure.
- Oil seepage around the PTO mounting flange: Failed seals or gaskets allow transmission fluid to escape, often visible as drips near the 0730365125: TYPE PLATE area, reducing lubrication and risking gear damage.
- Difficulty engaging or disengaging the PTO: A worn shift fork or damaged clutch mechanism prevents smooth activation, often accompanied by a hard lever feel or incomplete engagement.

Compatibility
This genuine ZF power take-off is designed for the WG 150 transmission family, but it also fits select models in the WG180 and WG200 series when used with the correct adapter kit. It is fully compatible with all WG150 variants, including the WG150-2, WG150-3, and WG150-4. For proper installation, ensure the 0631311009: GROOVED STUD is torqued to factory specifications to prevent loosening under vibration. The unit also integrates with the 4644106300: SHIFT SYSTEM for precise gear selection and the 4644306500: COVER PLATE to seal the housing.
