ZF 0501.223.097 HOSE PIPE for WG250/WG260

Overview

The ZF 0501.223.097 HOSE PIPE is a critical fluid conduit engineered specifically for the WG250, WG260, and WG310 transmission series. This OEM genuine part channels pressurized hydraulic oil between the valve body and the clutch packs, ensuring precise lubrication and cooling within the gear train. The SKU 0501.223.097 is designed to withstand high thermal loads and constant vibration, maintaining a leak-free seal under extreme operating conditions. When integrated with the TRANSMISSION HOUSING, this hose pipe guarantees uninterrupted fluid flow, directly impacting shift quality and overall transmission longevity.

Symptoms of Failure

• Hydraulic fluid seepage around the hose pipe connection points – Visible oil drips or wet spots near the transmission housing indicate a compromised seal or cracked pipe wall, often leading to low fluid levels.
• Erratic or delayed gear engagement – A restricted or leaking hose pipe reduces clutch apply pressure, causing hesitation when shifting from neutral to drive or reverse.
• Overheating transmission fluid – Insufficient oil flow due to a collapsed or blocked hose pipe prevents proper heat dissipation, triggering thermal warnings or burnt fluid odor.
• Whining or humming noise during operation – Air ingestion through a damaged hose pipe creates cavitation, producing audible noise that worsens under load.

Technical Specifications

Compatibility

This hose pipe is a direct fit for ZF WG series powershift transmissions, specifically the WG180, WG200, WG250, WG260, and WG310 models. It is commonly used in construction equipment such as wheel loaders, graders, and forklifts from manufacturers like Volvo, Liebherr, and Caterpillar. The part interfaces seamlessly with the HOUSING and the COVER assembly, requiring secure fastening with the HEXAGON SCREW to prevent fluid bypass.
