Overview
The ZF 4657.154.014 Power Take-Off (PTO) is a critical auxiliary drive component engineered specifically for the WG 190 and WG 210 series transmissions. This OEM genuine part, identified by SKU 4657.154.014, mounts directly to the transmission housing to divert engine power to hydraulic pumps, compressors, or other secondary equipment. It interfaces seamlessly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT, ensuring precise alignment and torque transfer. As a genuine ZF component, it guarantees factory tolerances and long service life in demanding industrial applications.
Symptoms of Failure
- Hydraulic pump slipping under load: When the PTO gear wears, you may notice intermittent power loss to auxiliary equipment, often described as “PTO gear slipping under heavy load.”
- Oil leaks around the PTO mounting flange: A failing seal or cracked housing can cause transmission fluid to weep from the joint, commonly searched as “ZF PTO oil leak WG190.”
- Unusual whining or grinding noises: Worn bearings or gear teeth produce a distinct metallic sound during engagement, a classic sign of “PTO bearing noise WG210.”
- Difficulty engaging or disengaging the PTO: Internal wear can cause the shift mechanism to bind, leading to “PTO not engaging smoothly” issues.

Frequently Asked Questions
Q: How do I know if the 4657.154.014 PTO is compatible with my WG190 transmission?
A: This PTO is designed for WG190 and WG210 models. Check your transmission serial number and ensure the mounting flange matches the 6-bolt pattern. For WG180 or WG200 applications, verify that the HOUSING REAR PART is the correct variant.
Q: What causes oil leaks from the PTO mounting area?
A: Oil leaks typically stem from a worn O-ring or gasket between the PTO and the TRANSMISSION HOUSING. Over-tightening bolts or a damaged CYLINDRICAL PIN can also cause misalignment and leakage.
Q: Can I replace just the PTO gear without replacing the housing?
A: Yes, the gear is serviceable separately. However, if the HOUS.FRONT SECT shows scoring or cracks, we recommend replacing both components to prevent future failure.
