Overview
The ZF 0750.147.014 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG150 and WG200 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 gearbox. As an original ZF component, the SKU 0750.147.014 guarantees precise fitment and material integrity, preventing fluid bypass that can compromise shift quality. This hose pipe is often replaced during major overhauls alongside the TRANSMISSION HOUSING (4642101047) or the TRANSMISSION HOUSING (4642301207) to restore full hydraulic circuit performance.
Symptoms of Failure
When the 0750.147.014 hose pipe deteriorates, operators typically encounter these specific failure indicators:
- Hydraulic oil leakage at the transmission cooler line connection – Visible drips or wet spots around the hose fittings indicate compromised sealing, often leading to low fluid levels.
- Erratic gear engagement or delayed shifting – A cracked or collapsed hose pipe reduces line pressure, causing hesitation when shifting between forward and reverse gears.
- Overheating transmission fluid – Restricted flow through a kinked or internally delaminated hose pipe prevents adequate oil cooling, triggering thermal warnings.
- Audible whining from the pump circuit – Air ingestion through a porous hose pipe creates cavitation noise, particularly under load.

Compatibility
This hose pipe is a direct replacement for ZF WG series transmissions, specifically the WG150 and WG200 models. It is also compatible with the WG180 variant when used in cooler return circuits. The part interfaces with the TYPE PLATE (0730365067) for correct routing identification and is secured using the GROOVED STUD (0631311009) on the housing flange. Always verify your transmission serial number against the WG150 or WG200 parts catalog before ordering.
