Overview
The ZF 0750.147.265 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 210 Series transmission. This OEM genuine part channels pressurized hydraulic oil between the valve body and the clutch drum assembly, ensuring precise actuation of gear shifts. Positioned within the transmission’s internal lubrication circuit, the hose pipe maintains consistent flow to prevent overheating and component wear. The SKU 0750.147.265 is manufactured to ZF’s exacting tolerances, guaranteeing a leak-proof seal under high-pressure operating conditions. When replacing this part, it is common to also inspect the 4657101042: TRANSMISSION HOUSING for cracks or distortion that could compromise alignment.
Symptoms of Failure
- Hydraulic fluid seepage near the transmission bell housing: A worn 0750.147.265 hose pipe often develops micro-cracks, leading to slow oil leaks that leave puddles under the vehicle. This is a common search query for “ZF WG210 oil leak from hose pipe.”
- Delayed or harsh gear engagement: When the hose pipe loses internal pressure due to swelling or collapse, clutch packs receive insufficient fluid, causing slipping or jerky shifts—often searched as “transmission slipping after hose replacement.”
- Overheating transmission fluid: A restricted hose pipe reduces oil flow to the cooler, triggering temperature warnings. Technicians frequently search for “ZF transmission overheating fix hose pipe.”
- Erratic shift timing in reverse gear: The hose pipe’s failure to deliver consistent pressure to the rear clutch pack results in delayed reverse engagement, a symptom often queried as “WG210 reverse gear slipping.”

Compatibility
This hose pipe is designed for the ZF WG 210 Series, but it also fits several other ZF off-highway transmissions due to shared hydraulic architectures. Compatible models include the WG 180, WG 200, WG 211, and WG 220 series. It is a direct replacement for units built between 2005 and 2020. When installing, always verify the condition of the 4657201028: HOUS.FRONT SECT and 4657201013: HOUSING REAR PART to ensure proper routing and clamping. Additionally, the 0631306792: CYLINDRICAL PIN must be checked for wear as it secures the hose pipe bracket to the housing.
