Overview
The ZF 4657.155.414 POWER TAKE-OFF is a critical OEM genuine component engineered specifically for the WG 210 Series transmission. This unit transfers engine torque to auxiliary hydraulic systems, such as dump truck hoists or concrete mixer drums, by engaging directly with the transmission’s gear train. As a bolt-on assembly, it sits on the side of the WG210 housing, providing a reliable power source without requiring a separate driveline. The SKU 4657.155.414 is precision-machined to ZF’s factory tolerances, ensuring seamless integration with the TRANSMISSION HOUSING and the HOUS.FRONT SECT for leak-free operation.
Symptoms of Failure
When the 4657.155.414 PTO begins to wear, operators may notice these specific failure indicators:
- Oil leaks at the PTO mounting flange – A common sign of a degraded gasket or cracked housing, often visible as drips beneath the vehicle.
- Intermittent gear slipping under load – The PTO may disengage or chatter when powering hydraulic pumps, reducing system pressure.
- Unusual grinding or whining noises – Worn bearings or gear teeth inside the PTO produce audible distress, especially during engagement.
- Difficulty engaging or disengaging the PTO – A failing shift mechanism or damaged internal splines can cause stubborn operation.
