Overview
The ZF 4616.119.014 POWER TAKE-OFF is a critical OEM genuine component engineered specifically for the WG 65 Series transmission family. This unit interfaces directly with the transmission housing to divert engine torque to auxiliary hydraulic systems, such as dump truck hoists or concrete mixer drums. The SKU 4616.119.014 ensures precise gear engagement and oil flow control within the PTO assembly. When installed correctly, it provides a reliable power extraction point without compromising the main driveline integrity. This genuine ZF part guarantees exact tolerances and material specifications required for heavy-duty commercial applications.
Symptoms of Failure
- Hydraulic system pressure loss or intermittent operation – A worn 4616.119.014 unit often fails to maintain consistent oil flow, causing sluggish auxiliary equipment response.
- Audible gear whine or grinding noise during PTO engagement – Internal bearing or gear wear within this power take-off produces distinct metallic sounds, especially under load.
- External oil seepage around the PTO mounting flange – Degraded seals allow transmission fluid to escape, leaving visible drips on the housing and surrounding components.
- Difficulty engaging or disengaging the PTO lever – Mechanical binding or internal shaft damage prevents smooth operation, often accompanied by a stiff shift feel.

Compatibility
This power take-off is primarily designed for the WG 65 Series transmission, but it also fits select ZF models including the WG180, WG200, and WG210. The 4616.119.014 unit is compatible with both standard and high-torque auxiliary systems found in vocational trucks and construction equipment. Always verify the transmission model and PTO opening pattern before installation. For proper mounting, use the 0636011038 HEXAGON SCREW and 0636011118 HEXAGON SCREW to secure the unit to the 4616101065 TRANSMISSION HOUSING. The 0636016015 HEXAGON SCREW is also required for the cover plate assembly.
