Overview
The ZF 0750.147.017 HOSE PIPE is a critical fluid conduit engineered for the WG181, WG200, and WG201 transmission series. This OEM genuine part channels pressurized hydraulic oil between the valve block and the transmission housing, ensuring consistent clutch engagement and torque converter lubrication. The SKU 0750.147.017 is specifically designed to withstand high thermal loads and vibration fatigue in heavy-duty industrial applications. Proper routing of this hose pipe prevents pressure drops that can compromise shift quality, making it an essential component for maintaining transmission integrity alongside the TRANSMISSION HOUSING and HOUSING assemblies.
Symptoms of Failure
- External hydraulic oil leaks near the transmission bell housing – Cracking or chafing of the hose pipe wall causes visible fluid drips, often mistaken for seal failures. This is a common long-tail search query for “ZF WG200 oil leak fix.”
- Erratic gear engagement or delayed shifting – A compromised hose pipe reduces line pressure, leading to soft shifts or clutch slip during load changes.
- Overheating transmission fluid – Restricted flow through a collapsed or kinked hose pipe starves the cooler circuit, triggering thermal alarms on the TYPE PLATE specifications.
- Audible whining or cavitation noise – Air ingestion through a cracked hose pipe creates a high-pitched sound during acceleration, indicating imminent pump damage.

Compatibility
This hose pipe is validated for the following ZF transmission models: WG180, WG181, WG200, WG201, and WG250 series. It directly replaces the original equipment line in vehicles equipped with the GROOVED STUD mounting system. The 0750.147.017 is not interchangeable with earlier WG150 or WG160 variants due to different port orientations. Always verify the routing path against your existing TRANSMISSION HOUSING casting numbers to ensure proper fitment.
