Overview
The ZF 4642.155.019 POWER TAKE-OFF is a critical OEM genuine component engineered specifically for the WG 150 Series transmission family. This unit transfers engine torque to auxiliary hydraulic systems, such as pumps for dump bodies, cranes, or refuse equipment. Positioned on the transmission housing, it interfaces directly with the gear train to deliver reliable power output. The SKU 4642.155.019 ensures exact fitment and durability, reducing downtime in heavy-duty commercial applications. For complete assembly integrity, this PTO works in conjunction with the 4642101047: TRANSMISSION HOUSING and the 4642301207: TRANSMISSION HOUSING, which provide structural support and alignment.
Symptoms of Failure
When the ZF 4642.155.019 POWER TAKE-OFF begins to wear, operators may notice these specific failure indicators:
- Hydraulic oil leaks around the PTO mounting flange – often caused by seal degradation, leading to fluid loss and system inefficiency.
- Gear slipping or intermittent power take-off engagement – results from worn internal splines or bearing fatigue, reducing torque transfer to auxiliary equipment.
- Unusual whining or grinding noises during PTO activation – indicates bearing failure or gear tooth damage, requiring immediate inspection.
- Vibration at the PTO output shaft – suggests imbalance or misalignment, often linked to housing wear or loose fasteners like the 0631311009: GROOVED STUD.
