Overview
The ZF 4657.155.400 POWER TAKE-OFF is a critical auxiliary drive component engineered specifically for the WG210 series transmission. This OEM genuine part, identified by SKU 4657.155.400, mounts directly to the transmission housing to divert engine power to hydraulic pumps, compressors, or other secondary equipment. As a factory-specification unit, it ensures precise gear engagement and torque transfer without compromising the main driveline’s integrity. The PTO assembly interfaces seamlessly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT, forming a robust power distribution network for heavy-duty industrial applications.
Symptoms of Failure
When the ZF 4657.155.400 POWER TAKE-OFF begins to degrade, operators may notice these specific failure indicators:
- Hydraulic pump gear slipping under load — A worn PTO gear loses bite, causing intermittent power loss to auxiliary equipment during operation.
- Oil seepage at the PTO mounting flange — Deteriorating seals allow transmission fluid to escape, often visible as drips near the HOUSING REAR PART interface.
- Grinding noise during PTO engagement — Worn bearings or misaligned shift collars produce metallic scraping sounds when activating the power take-off.
- Excessive vibration at idle — A failing output shaft or damaged CYLINDRICAL PIN creates driveline shudder that intensifies with engine RPM.
