ZF 4657.154.016 POWER TAKE-OFF for WG210 | OEM Genuine Part

Overview

The ZF 4657.154.016 POWER TAKE-OFF is a critical hydraulic interface unit engineered specifically for the WG 210 Series transmission. This OEM genuine part, identified by SKU 4657.154.016, mounts directly to the transmission housing to divert engine power to auxiliary hydraulic pumps. It is positioned on the rear or side face of the transmission, depending on the specific chassis configuration, and serves as the primary mechanical link between the driveline and external equipment such as dump bodies, winches, or concrete mixers. Precision-machined from high-strength alloy steel, this PTO ensures seamless torque transfer while maintaining the structural integrity of the entire driveline assembly.

Symptoms of Failure

When the ZF 4657.154.016 POWER TAKE-OFF begins to wear, operators often notice hydraulic oil leaks around the PTO mounting flange, which can lead to low system pressure and erratic equipment operation. Another common failure symptom is gear slipping or grinding noises during engagement, indicating worn internal splines or bearing degradation. You may also experience vibration or shuddering under load, particularly when the PTO is engaged at low engine RPM, which suggests misalignment or fatigue in the drive gear. Finally, inability to disengage the PTO or a stuck shift mechanism points to corrosion or debris contamination within the shift fork assembly.

Technical Specifications

Compatibility

This PTO is designed primarily for the ZF WG 210 Series transmission, but it also fits select models in the WG180, WG200, and WG250 families when used with the correct adapter kit. It is commonly found in medium-duty trucks, fire apparatus, and municipal vehicles. For proper installation, ensure the transmission housing is free of cracks or wear—consider replacing the TRANSMISSION HOUSING if damage is present. The PTO mates directly to the HOUS.FRONT SECT and the HOUSING REAR PART; alignment is secured using a CYLINDRICAL PIN to prevent rotational shift during high-torque operation.
