Overview
The ZF 4657.155.413 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 drive gear, enabling auxiliary hydraulic or mechanical power extraction for applications such as dump trucks, concrete mixers, and refuse vehicles. The SKU 4657.155.413 is precision-machined to ZF’s original tolerances, ensuring seamless integration with the 4657101075: TRANSMISSION HOUSING and the 4657201151: HOUS.FRONT SECT. When installed correctly, this PTO delivers reliable torque transfer without parasitic drag, making it indispensable for operators requiring continuous auxiliary power.
Symptoms of Failure
- Oil seepage at the PTO mounting flange: Worn seals or gasket degradation cause transmission fluid to leak externally, often noticed as drips under the vehicle after shutdown.
- Grinding or whining noise during engagement: Internal gear wear or bearing failure produces audible metallic sounds, especially when the PTO is under load.
- Intermittent power loss to auxiliary equipment: Slipping gears or a damaged shift fork result in inconsistent hydraulic pump or winch operation, reducing productivity.
- Difficulty shifting PTO in or out of gear: Sticking actuation mechanisms or worn detent springs prevent clean engagement, leading to operator frustration and potential driveline damage.

Compatibility
This power take-off is primarily designed for the ZF WG 210 Series transmission, but it also fits select variants of the WG 180, WG 200, and WG 250 models when used with the correct adapter kit. The unit is compatible with both direct-mount and remote-mount hydraulic pump configurations. For proper installation, always verify that the 4657201160: HOUSING REAR PART is free of cracks and that the 0631306816: CYLINDRICAL PIN is correctly aligned to prevent misalignment. Applications include municipal trucks, construction equipment, and agricultural machinery where a rear-mounted PTO is required.
