ZF 0501.223.102 HOSE PIPE for WG260 | OEM Genuine Part

Overview

The ZF 0501.223.102 HOSE PIPE is a critical fluid conduit engineered specifically for the WG 260 and WG 310 transmission series. This OEM genuine part, identified by SKU 0501.223.102, routes pressurized hydraulic oil between the valve body and the clutch pack assembly, ensuring consistent lubrication and cooling under heavy load. Positioned within the lower sump area, it connects directly to the TRANSMISSION HOUSING and the HOUSING to maintain uninterrupted fluid flow. Without this hose pipe, the transmission cannot sustain proper hydraulic pressure, leading to immediate operational degradation.

Symptoms of Failure

When the ZF 0501.223.102 HOSE PIPE begins to fail, operators often notice these specific warning signs:

• Hydraulic fluid seepage at the hose pipe connection points – Look for wet spots near the COVER or the HEXAGON SCREW mounting points; this indicates a cracked or swollen hose pipe.
• Delayed or harsh gear engagement – A compromised hose pipe reduces line pressure, causing sluggish shifts or abrupt clutch application.
• Overheating transmission fluid – Restricted flow through a collapsed hose pipe prevents proper cooling, leading to elevated sump temperatures.
• Low transmission fluid level without visible external leaks – Internal weeping from the hose pipe into the bell housing can mimic a slow leak.

Technical Specifications

Compatibility

This genuine ZF hose pipe is designed for the WG 260 and WG 310 series transmissions. It also fits select models in the WG 180 and WG 200 families where the hydraulic routing matches the same port spacing. Always verify the TRANSMISSION HOUSING casting number and the HOUSING configuration before installation. The part is not compatible with older WG 120 or WG 150 series without adapter fittings.
