Overview
The ZF 4657.155.410 POWER TAKE-OFF is a critical auxiliary drive unit designed for seamless integration within the WG171, WG190, and WG191 transmission series. This OEM genuine part, identified by SKU 4657.155.410, sits on the side of the transmission housing to transfer engine power to hydraulic pumps or other secondary equipment. It engages directly with the transmission’s internal gearing, providing a reliable mechanical interface for demanding industrial applications. When paired with the 4656101030: TRANSMISSION HOUSING, this PTO ensures optimal alignment and torque transfer, making it indispensable for heavy-duty machinery where consistent power output is non-negotiable.
Symptoms of Failure
When the ZF 4657.155.410 POWER TAKE-OFF begins to wear, operators often notice specific performance issues. Look for these failure indicators to diagnose problems early:
- Oil leaks around the PTO mounting flange: Worn seals or gaskets cause transmission fluid to seep out, often visible as drips under the vehicle or machine.
- Gear slipping or intermittent power loss: Damaged internal gears or a failing clutch mechanism result in erratic engagement, especially under load.
- Unusual grinding or whining noises: Bearing wear or misalignment produces audible sounds during PTO activation, indicating imminent failure.
- Difficulty engaging or disengaging the PTO: A sticking shift mechanism or corroded components prevent smooth operation, leading to operational delays.

Frequently Asked Questions
Q: How do I know if the 4657.155.410 PTO is failing?
A: Common signs include visible oil leaks near the mounting flange, grinding noises during engagement, and intermittent power loss to the hydraulic pump. Regular inspection of the seal and gear condition is recommended.
Q: Can this PTO be installed on a WG180 transmission?
A: Yes, the 4657.155.410 is compatible with WG180 models that share the same bolt pattern and gear interface as the WG171 series. Always cross-reference your transmission’s serial number with the OEM specifications.
Q: What maintenance is required for this power take-off?
A: Periodically check the O-ring (part 0634313514) and cap screws (0636100803) for wear. Ensure the screen sheet (4656201015) is clean to prevent oil contamination, which can accelerate gear damage.
