ZF 4644.155.006 POWER TAKE-OFF for WG200 | OEM Genuine Part

Overview

The ZF 4644.155.006 POWER TAKE-OFF is a critical hydraulic interface unit engineered specifically for the WG 200 Series transmissions. This OEM genuine part, identified by SKU 4644.155.006, mounts directly to the transmission housing to divert engine power to auxiliary hydraulic systems such as dump bodies, winches, or concrete mixers. It sits on the side of the gearbox, engaging with the transmission’s internal drive gear to provide a reliable power source without interrupting the primary driveline. Precision-machined from high-strength alloys, this PTO ensures seamless torque transfer and long service life in demanding vocational applications.

Symptoms of Failure

When the ZF 4644.155.006 POWER TAKE-OFF begins to wear, operators may notice several distinct failure indicators. Oil leaks around the PTO mounting flange are common, often caused by degraded seals or gasket failure. Gear slipping or intermittent power loss to auxiliary equipment suggests internal gear wear or bearing fatigue. Unusual grinding or whining noises during engagement point to damaged internal components. Additionally, difficulty engaging or disengaging the PTO can indicate a failing shift mechanism or worn clutch hub. Addressing these symptoms early prevents secondary damage to the TRANSMISSION HOUSING and related assemblies.

Technical Specifications

Compatibility

This ZF 4644.155.006 POWER TAKE-OFF is designed primarily for the WG 200 Series transmissions, including models WG180, WG200, and WG210. It also fits select variants of the ZF 6WG and 5WG series used in medium-duty trucks, fire apparatus, and construction equipment. For proper installation, ensure the transmission housing is free of cracks or wear; consider replacing the TRANSMISSION HOUSING if damage is present. Always verify the TYPE PLATE on your transmission to confirm model compatibility. Secure the PTO using the correct GROOVED STUD for optimal clamping force.
