ZF 4616.136.016 POWER TAKE-OFF for WG65 | OEM Genuine Part

Overview

The ZF 4616.136.016 POWER TAKE-OFF is an OEM genuine component engineered specifically for the WG 65 Series transmission family. This PTO unit transfers engine torque to auxiliary hydraulic systems, such as dump truck hoists or concrete mixer drums, by engaging directly with the transmission’s internal gearing. The part number 4616.136.016 is a direct-fit replacement that restores full power take-off functionality. It mounts to the side of the transmission housing, where it interfaces with the main gear train. For proper sealing and structural integrity, this PTO is installed alongside the 4616101101: TRANSMISSION HOUSING and secured using the 0636011118: HEXAGON SCREW.

Symptoms of Failure

When the ZF 4616.136.016 PTO begins to wear, operators may notice several distinct failure indicators. Oil leaks around the PTO mounting flange are common, often caused by degraded gaskets or housing cracks. Gear slipping or intermittent power delivery to the auxiliary system signals worn internal splines or bearing failure. Unusual grinding or whining noises during PTO engagement point to damaged gear teeth. Difficulty engaging or disengaging the PTO can result from a seized shift mechanism or broken fork. If you observe these symptoms, inspect the 4616301304: HOUSING and 4616301309: HOUSING for alignment issues.
