Overview
The ZF 0501.210.150 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 65 Series transmission. This OEM genuine part channels pressurized transmission oil between the valve body and the cooler circuit, ensuring consistent lubrication and thermal regulation during high-torque operations. As an integral element of the hydraulic circuit, the SKU 0501.210.150 maintains precise fluid flow to prevent overheating and component wear. When paired with the 4616105413: OUTPUT assembly, this hose pipe supports reliable power delivery in heavy-duty industrial applications.
Symptoms of Failure
- Transmission fluid puddles under the vehicle: A cracked or swollen 0501.210.150 hose pipe often causes visible oil leaks near the WG65 housing, especially after thermal cycling.
- Erratic gear engagement or slipping: Reduced hydraulic pressure from a compromised hose leads to delayed shifts or clutch slippage under load.
- Overheating transmission fluid: Restricted flow through a collapsed hose pipe prevents proper cooling, triggering temperature warnings on the dashboard.
- Whining or groaning noises from the transmission: Air ingestion through a damaged hose creates cavitation sounds, particularly during cold starts or sustained operation.

Compatibility
This hose pipe is designed for the ZF WG 65 Series transmission family, including models such as WG65, WG80, WG120, WG150, WG180, and WG200. It also fits select ZF Ecomat 4HP and 5HP variants where the cooler line routing matches the WG65 architecture. For complete sealing during installation, always replace the 0636011038: HEXAGON SCREW and inspect the 4616203017: OUTPUT FLANGE for wear. The 4616101117: TRANSMISSION HOUSING should be checked for cracks or corrosion when servicing this hose pipe.
