Overview
The ZF 4657.154.002 POWER TAKE-OFF is a critical OEM genuine component engineered for the WG190, WG210, and WG230 series transmissions. This unit serves as the mechanical interface that diverts engine power from the transmission to drive auxiliary hydraulic pumps or other secondary equipment. Positioned on the side of the main gearbox, the PTO engages via a sliding gear mechanism that connects directly to the transmission’s countershaft. The SKU 4657.154.002 is manufactured to ZF’s exacting tolerances, ensuring seamless integration with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain proper gear alignment and load distribution.
Symptoms of Failure
- Oil leaks around the PTO mounting flange: When the 4657.154.002 unit wears, degraded seals allow transmission fluid to escape, often visible as drips beneath the vehicle. This is a common symptom in high-mileage WG190 applications.
- Grinding noise during PTO engagement: Worn internal gears or bearings produce a distinct metallic grinding sound when the power take-off is activated, indicating the need for immediate replacement.
- Intermittent power loss to auxiliary equipment: A failing PTO may slip under load, causing hydraulic pumps or winches to lose pressure or stop working entirely during operation.
- Vibration at the PTO housing: Excessive play in the output shaft or damaged mounting points leads to noticeable vibration, which can also affect the HOUSING REAR PART if left unaddressed.

Frequently Asked Questions
Q: Can the 4657.154.002 be installed on a WG210 without modifying the housing?
A: Yes, this PTO is a direct-fit OEM part for the WG210 series. However, you must ensure the CYLINDRICAL PIN is correctly seated to prevent misalignment during installation.
Q: What is the typical lifespan of this power take-off under normal operating conditions?
A: With proper lubrication and regular maintenance, the 4657.154.002 typically lasts 5,000 to 8,000 operating hours. Symptoms like oil leaks or grinding noise indicate it is time for replacement.
Q: Does this part include the mounting hardware?
A: The PTO unit itself does not include fasteners. We recommend ordering the CAP SCREW and FIXING PLATE separately to complete the installation.
