Overview
The ZF 4657.154.015 POWER TAKE-OFF is a critical OEM genuine component engineered for the WG 210 Series transmission. This unit serves as the primary interface for transferring engine torque to auxiliary hydraulic pumps, compressors, or generators, directly mounted to the transmission housing. Designed to handle high intermittent loads, the PTO engages via a pneumatic or mechanical shift mechanism, ensuring seamless power distribution without interrupting the driveline. The SKU 4657.154.015 is precision-machined to ZF’s exacting tolerances, guaranteeing a direct bolt-on replacement for commercial vehicles and industrial machinery. It sits on the side of the transmission, interfacing with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain structural integrity under full load.
Symptoms of Failure
When the ZF 4657.154.015 begins to wear, operators often notice oil leaks around the PTO mounting flange, a common failure mode caused by degraded seals or gasket fatigue. Another frequent issue is gear slipping under load, where the PTO disengages intermittently during operation, leading to erratic pump performance. You may also detect abnormal grinding or whining noises from the PTO housing, indicating bearing wear or gear tooth damage. In severe cases, complete loss of auxiliary power occurs, requiring immediate replacement to avoid downtime. These symptoms are often linked to misalignment with the HOUSING REAR PART or a worn CYLINDRICAL PIN that secures the shift fork.

Compatibility
This ZF 4657.154.015 POWER TAKE-OFF is specifically designed for the WG 210 Series transmission, but it also fits select models in the WG180, WG200, and WG250 families when using the correct adapter kit. It is compatible with ZF’s 6-speed and 8-speed powershift transmissions found in agricultural tractors, construction loaders, and material handlers. Always verify the PTO drive gear count and housing orientation against your transmission’s TRANSMISSION HOUSING to ensure proper engagement. For installations requiring additional support, the HOUS.FRONT SECT and HOUSING REAR PART must be inspected for wear to prevent misalignment.
