Overview
The ZF 0501.207.967 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 250 transmission series. This OEM genuine part channels pressurized hydraulic oil between the valve body and the cooler circuit, ensuring consistent lubrication and thermal regulation within the gear train. As an original equipment manufacturer (OEM) component, SKU 0501.207.967 guarantees exact fitment and material integrity, preventing contamination ingress that can degrade clutch pack performance. This hose pipe integrates directly with the TRANSMISSION HOUSING and the HOUSING assembly, forming a sealed conduit that maintains system pressure during high-torque operations.
Symptoms of Failure
When the ZF 0501.207.967 HOSE PIPE deteriorates, operators typically encounter these specific failure indicators:
- External hydraulic oil seepage – Cracks in the hose wall cause visible fluid loss near the transmission bell housing, often mistaken for a main seal leak.
- Erratic gear engagement under load – Reduced line pressure from a compromised hose leads to delayed or harsh shifts, particularly when climbing grades.
- Elevated transmission operating temperature – Restricted oil flow through a collapsed hose pipe reduces cooler circuit efficiency, triggering overheat warnings.
- Air entrainment in the fluid – A porous hose draws air into the system, producing foamy oil and erratic clutch modulation during low-speed maneuvers.

Compatibility
This hose pipe is primarily validated for the ZF WG 250 series, but its hydraulic routing design also supports the WG 180, WG 200, and WG 210 transmissions when used with the appropriate COVER and CONNECTING PART. It is not compatible with the WG 120 or WG 150 series due to different port spacing. Always verify the presence of the original TYPE PLATE on the housing to confirm model revision before installation.
