Overview
The ZF 4657.154.012 POWER TAKE-OFF is a critical OEM genuine component engineered specifically for the WG 210 Series transmission. This unit transfers engine power from the transmission to auxiliary hydraulic systems, such as pumps for dump bodies, cranes, or refuse equipment. As a direct-fit replacement, the SKU 4657.154.012 ensures seamless integration with the driveline, mounting directly to the TRANSMISSION HOUSING to deliver reliable torque output. Designed for heavy-duty commercial applications, this PTO maintains the durability and performance standards expected from ZF’s WG series.
Symptoms of Failure
When the ZF 4657.154.012 POWER TAKE-OFF begins to wear, operators may notice specific performance issues. Look for these failure symptoms to diagnose problems early:
- Hydraulic pump gear slipping under load – A worn PTO gear can cause intermittent power loss to auxiliary equipment, especially during high-torque demands.
- Oil leaks around the PTO mounting flange – Degraded seals or gaskets often lead to transmission fluid seepage, visible as drips near the HOUS.FRONT SECT interface.
- Unusual grinding or whining noise during engagement – Worn bearings or misaligned shafts produce audible sounds when the PTO is activated, indicating internal component fatigue.
- Delayed or incomplete PTO engagement – A failing shift mechanism or damaged internal splines can prevent the PTO from locking into gear, reducing operational efficiency.

Compatibility
This POWER TAKE-OFF is primarily designed for the ZF WG 210 Series transmission, but it also fits select models in the WG180, WG200, and WG220 families. It is commonly used in medium- and heavy-duty trucks, municipal vehicles, and construction equipment. For proper installation, ensure the HOUSING REAR PART is correctly aligned, and secure the assembly with the CYLINDRICAL PIN to prevent rotational movement. Always verify your transmission model and PTO drive gear configuration before ordering.

Frequently Asked Questions
Q: Can the ZF 4657.154.012 be used on a WG200 transmission?
A: Yes, this PTO is compatible with WG200 models that share the same drive gear configuration and mounting pattern as the WG210. Always check your transmission’s PTO opening dimensions and gear tooth count to confirm fitment.
Q: What causes oil leaks at the PTO mounting point?
A: Oil leaks typically stem from a worn O-ring or gasket between the PTO and the transmission housing. Inspect the TRANSMISSION HOUSING for cracks or damage, and replace the seal during installation to prevent future leakage.
Q: How do I know if my PTO gear is slipping?
A: Slipping often presents as intermittent hydraulic pump operation or a sudden drop in auxiliary power under load. Listen for a rattling or chattering sound from the PTO area, and check the engagement linkage for wear. Replacing the unit with the 4657.154.012 restores full torque transfer.
