Overview
The ZF 0501.207.964 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG250 and WG260 transmission series. This OEM genuine part channels pressurized hydraulic oil between the valve body and the clutch pack assembly, ensuring precise actuation and consistent lubrication under high-torque conditions. As an original equipment manufacturer (OEM) component, the SKU 0501.207.964 guarantees exact fitment and material integrity, eliminating the risk of hose collapse or leakage that can compromise shift quality. This hose pipe is installed within the main transmission casing, directly adjacent to the TRANSMISSION HOUSING and the HOUSING assembly, where it withstands continuous exposure to ATF temperatures up to 120°C.
Symptoms of Failure
- External hydraulic oil leaks near the transmission bell housing: A cracked or degraded 0501.207.964 hose pipe will weep ATF, leaving visible puddles under the vehicle and causing low fluid levels.
- Erratic gear engagement or delayed shifting: When this hose pipe loses internal pressure integrity, the clutch packs receive insufficient hydraulic force, leading to harsh or slipping shifts during acceleration.
- Transmission overheating accompanied by burnt fluid smell: A restricted or collapsed hose pipe reduces oil flow to the cooler circuit, causing rapid temperature spikes and thermal degradation of the transmission fluid.
- Whining or groaning noise from the transmission pump: Air ingestion through a fractured hose pipe creates cavitation, producing audible distress sounds and reducing pump efficiency.

Compatibility
This genuine ZF hose pipe is designed for the WG250 and WG260 series transmissions, commonly found in heavy-duty trucks, construction equipment, and agricultural machinery. Based on the part type and hydraulic routing, the 0501.207.964 is also compatible with the WG180, WG200, and WG210 models when used in similar oil circuit configurations. Always verify fitment against your transmission serial number, as the hose pipe interfaces directly with the COVER plate and is secured using the HEXAGON SCREW fasteners. For optimal sealing, inspect the mating surfaces on the TRANSMISSION HOUSING during replacement.
