Overview
The ZF 0750.147.115 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG150 and WG200 series transmissions. This OEM genuine part channels pressurized transmission fluid between the valve body and the cooler circuit, ensuring consistent lubrication and thermal regulation during high-torque operations. As a direct replacement for the SKU 0750.147.115, this hose pipe maintains factory-specified flow rates and pressure tolerances, preventing cavitation and overheating in heavy-duty industrial applications. It integrates seamlessly with the 4642101109: TRANSMISSION HOUSING and 4642301205: TRANSMISSION HOUSING, forming a leak-proof hydraulic circuit essential for gear engagement and clutch pack actuation.
Symptoms of Failure
- External transmission fluid leaks near the cooler lines: A cracked or swollen hose pipe allows ATF to escape, leaving puddles under the vehicle and causing gradual fluid loss.
- Erratic gear engagement or delayed shifting: Restricted fluid flow from a collapsed hose pipe reduces hydraulic pressure, leading to harsh shifts or slipping in forward and reverse gears.
- Elevated transmission operating temperature: When the hose pipe fails to deliver adequate coolant flow, the transmission overheats, triggering warning lights and potential torque converter damage.
- Visible hose surface deterioration: Cracking, blistering, or hardening of the rubber exterior indicates material fatigue, often accompanied by a burning oil smell from fluid starvation.

Compatibility
This hose pipe is engineered for the ZF WG150 and WG200 series transmissions, including the WG150, WG180, WG200, and WG210 variants. It is also compatible with certain off-highway and marine derivatives using the same hydraulic circuit architecture. For proper installation, ensure the 0730365125: TYPE PLATE matches your transmission model, and secure the assembly using the 0631311009: GROOVED STUD to prevent vibration-induced loosening. Always verify the routing path against the factory service manual to avoid kinking.
