Overview
The ZF 0501.207.968 HOSE PIPE is a critical fluid conduit engineered specifically for the WG 250 and WG 260 transmission series. This OEM genuine part ensures precise hydraulic pressure delivery and lubrication flow within the gearbox assembly. Positioned between the valve body and the cooler circuit, the SKU 0501.207.968 maintains consistent oil volume to prevent thermal degradation during high-torque operations. As a direct replacement component, it restores the original factory sealing and flow characteristics essential for heavy-duty industrial applications.
Symptoms of Failure
- Hydraulic fluid seepage at connection points: A worn 0501.207.968 often develops micro-cracks, leading to visible oil residue around the transmission housing joints, especially during cold starts.
- Erratic gear engagement under load: When this hose pipe degrades, internal pressure drops cause delayed or harsh shifting in WG250/WG260 units, particularly in reverse gear.
- Overheating transmission fluid: Restricted flow from a collapsed hose pipe raises operating temperatures beyond 100°C, triggering warning lights on industrial equipment dashboards.
- Whining noise during acceleration: Air ingestion through a compromised hose pipe creates a high-pitched sound, indicating cavitation in the hydraulic circuit.

Compatibility
This hose pipe is factory-specified for the ZF WG250 and WG260 transmission families. It also fits select WG180 and WG200 variants where the hydraulic circuit layout matches the original design. Always verify the routing path against your existing TRANSMISSION HOUSING before installation. The 0501.207.968 connects directly to the HOUSING assembly and is secured by the HEXAGON SCREW fasteners. For complete sealing, pair it with the COVER gasket to prevent contamination ingress.
