Overview
The ZF 0750.147.082 HOSE PIPE is a precision-engineered fluid conduit designed specifically for the WG 201 transmission series. This OEM genuine part channels hydraulic oil between the valve body and the cooler circuit, ensuring consistent lubrication and thermal regulation during high-torque operations. As a critical component in the transmission’s hydraulic loop, the SKU 0750.147.082 maintains proper line pressure and prevents contamination ingress. When installed alongside the 4644101160: TRANSMISSION HOUSING, this hose pipe creates a sealed pathway that supports the entire gear train’s cooling demands.
Symptoms of Failure
- Hydraulic fluid seepage at connection points: A degraded 0750.147.082 hose pipe often causes visible oil weeping around the crimped fittings, leading to low fluid levels and eventual gear slippage under load.
- Erratic shift timing during cold starts: When the internal lining collapses, restricted flow produces delayed clutch engagement, particularly noticeable in WG201 transmissions operating below 10°C.
- Overheating transmission warning: A blocked or kinked hose pipe reduces cooler flow, triggering thermal alarms after extended highway driving. This symptom frequently accompanies failures in the 4644301323: TRANSMISSION HOUSING assembly.
- Metallic debris in the oil pan: Internal hose degradation sheds rubber particles that circulate through the system, accelerating wear on the 4644301189: THREADED BUSH and valve body components.

Compatibility
This hose pipe is engineered for the ZF WG 201 series, but its hydraulic specifications also suit earlier WG180 and WG200 models when used with the correct adapter fittings. The 0750.147.082 interfaces directly with the 4475280043: SCREW PLUG port on the transmission housing. It is compatible with all WG201 variants produced after 2008, including the WG201-6 and WG201-8 configurations. For WG180 applications, verify the routing path clears the 4644301161: COVER PLATE before installation.
