Overview
The ZF 0750.147.266 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 210 Series transmission. This OEM genuine part, identified by SKU 0750.147.266, routes pressurized transmission fluid between the valve body and the cooler circuit, ensuring consistent hydraulic pressure for clutch engagement and gear shifts. Located within the transmission’s lower valve body assembly, this hose pipe connects directly to the 4657101042: TRANSMISSION HOUSING and interfaces with the 4657201028: HOUS.FRONT SECT to maintain a sealed oil circuit. Without a properly functioning hose pipe, the transmission cannot sustain the necessary lubrication and cooling flow, leading to premature wear of internal components.
Symptoms of Failure
When the ZF 0750.147.266 HOSE PIPE deteriorates, operators often notice these specific failure indicators:
- Transmission fluid leaks near the front housing: Cracks or abrasions in the hose pipe cause oil to weep around the 4657201013: HOUSING REAR PART, leaving puddles under the vehicle.
- Delayed or harsh gear engagement: A compromised hose reduces hydraulic pressure, resulting in sluggish shifts or abrupt clunking when moving from Neutral to Drive.
- Overheating transmission: Restricted fluid flow through a collapsed hose pipe prevents adequate cooling, causing the transmission to run hotter than normal.
- Intermittent gear slipping under load: When the hose pipe fails internally, pressure drops during acceleration, allowing clutches to slip momentarily.

Compatibility
This hose pipe is primarily designed for the ZF WG 210 Series, but it also fits several related transmission models that share the same hydraulic circuit architecture. Compatible transmissions include the WG180, WG200, and WG211 series. The part is secured in place using a 0631306792: CYLINDRICAL PIN that aligns the hose with the housing bores. Always verify your transmission’s serial number against the OEM parts catalog before installation, as minor revisions in later WG210 variants may require different hose routing.
