ZF 4657.155.405 POWER TAKE-OFF for WG210 | OEM Genuine Part

Overview

The ZF 4657.155.405 POWER TAKE-OFF is a critical OEM genuine component engineered specifically for the WG 210 Series transmission family. 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 geartrain. As a factory-spec part, the SKU 4657.155.405 ensures precise alignment and sealing within the PTO housing bore, preventing parasitic power loss. It mounts on the side of the transmission, often adjacent to the TRANSMISSION HOUSING, and interfaces with the HOUS.FRONT SECT for secure gear engagement.

Symptoms of Failure

• Hydraulic system pressure drop or slow implement response: When the PTO clutch pack wears, it cannot transmit full torque, causing sluggish operation of pumps.
• Oil seepage around the PTO mounting flange: A degraded shaft seal or housing gasket leads to visible ATF leaks, often mistaken for a main transmission leak.
• Grinding or whining noise during engagement: Worn bearings or gear teeth produce audible metallic sounds, especially under load.
• Intermittent PTO disengagement: A failing shift fork or worn splines on the output shaft cause the PTO to slip out of gear unexpectedly.

Technical Specifications

Compatibility

This PTO is designed for the ZF WG 210 Series, but it also fits select models in the WG180, WG200, and WG211 families when used with the correct adapter plate. It is commonly installed on ZF 6WG210, 5WG210, and 4WG210 transmissions found in off-highway trucks and heavy equipment. For proper installation, ensure the HOUSING REAR PART is free of debris and that the CYLINDRICAL PIN is aligned to prevent gear misalignment.
