Overview
The ZF 0501.214.895 GEAR PUMP is a critical hydraulic component engineered for the WG115, WG131, and WG160 series transmissions. This OEM genuine part is responsible for generating the necessary oil flow and pressure to actuate clutch packs, lubricate internal gears, and maintain thermal stability within the transmission housing. Positioned directly on the front section of the gearbox, this pump draws fluid from the sump and delivers it through the valve body. The SKU 0501.214.895 is a direct replacement unit that meets ZF’s stringent factory tolerances, ensuring consistent volumetric efficiency. When installed alongside the 4656101037: TRANSMISSION HOUSING, it forms the core hydraulic circuit that powers the entire drivetrain.
Symptoms of Failure
- Erratic gear engagement or slipping under load: A worn gear pump cannot maintain adequate line pressure, causing clutches to slip during acceleration or hill climbs.
- Whining or cavitation noise from the transmission: Air ingestion or worn gears produce a high-pitched whine that intensifies with engine RPM, indicating internal wear.
- Low hydraulic pressure at the test port: When the pump fails to generate the rated pressure (typically 12-18 bar), shift quality degrades and the transmission may enter limp mode.
- Visible oil leaks around the pump mounting flange: Degraded seals or a cracked 4656201075: HOUS.FRONT SECT can allow fluid to weep externally, leading to low oil levels and overheating.

Compatibility
This gear pump is designed for ZF’s WG and BP series powershift transmissions used in off-highway and industrial machinery. It is a direct fit for the WG115, WG131, WG160, WG171, WG190, WG191, WG210, WG211, and WG230 series, as well as the BP210 and BP230 models. The pump interfaces with the 4656201035: HOUSING REAR PART and the 4472239178: HOUSING REAR PART to complete the hydraulic assembly. Always verify the pump rotation direction (clockwise or counter-clockwise) against your specific transmission build before installation.
