ZF 4657.154.010 POWER TAKE-OFF for WG210 | OEM Genuine Part

Overview

The ZF 4657.154.010 POWER TAKE-OFF is a critical OEM genuine component engineered specifically for the WG 210 Series transmission family. This unit interfaces directly with the transmission’s main gear train to transfer engine power to auxiliary hydraulic systems, such as dump truck hoists, concrete mixer drums, or refuse packer mechanisms. Positioned on the side of the transmission housing, the PTO engages via a sliding gear mechanism and is secured by the TRANSMISSION HOUSING assembly. The SKU 4657.154.010 is precision-machined to ZF’s factory tolerances, ensuring seamless integration with the HOUS.FRONT SECT and HOUSING REAR PART for reliable torque delivery.

Symptoms of Failure

• Oil seepage at PTO mounting flange: Worn seals or gaskets cause transmission fluid to leak externally, often visible as drips beneath the vehicle. This is a common “ZF PTO oil leak” issue.
• Grinding noise during engagement: Damaged gear teeth or a worn shift fork produce a metallic grinding sound when the PTO is activated, indicating imminent gear slipping.
• Intermittent power loss to hydraulics: A failing internal bearing or misaligned shaft results in inconsistent pump speed, leading to “PTO not engaging fully” or “hydraulic system lag.”
• Excessive vibration at idle: Worn output shaft splines or a loose CYLINDRICAL PIN can cause noticeable shaking, accelerating wear on adjacent components.

Technical Specifications

Compatibility

This genuine ZF PTO is designed for the WG 210 Series but also fits select models in the WG180, WG200, and WG240 families when used with the correct adapter kit. It is commonly found on ZF 6WG210, 5WG200, and 4WG180 transmissions in medium-duty trucks and off-highway equipment. Always verify the housing interface matches your TRANSMISSION HOUSING flange pattern before installation.
