ZF 0501.212.309 HOSE PIPE for WG260/WG310 | OEM Genuine Part

Overview

The ZF 0501.212.309 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 260 and WG 310 transmission series. This OEM genuine part routes pressurized hydraulic oil between the valve body and the cooler circuit, ensuring consistent lubrication and thermal regulation within the gearbox. As a direct replacement for the original factory-installed line, the SKU 0501.212.309 maintains precise flow dynamics to prevent cavitation and overheating. This hose pipe interfaces directly with the 4646101141: TRANSMISSION HOUSING and the 4646301318: HOUSING, forming a sealed circuit that supports sustained heavy-duty operation.

Symptoms of Failure

When the ZF 0501.212.309 hose pipe deteriorates, operators typically notice these specific failure indicators:

• External hydraulic oil seepage around the transmission cooler line connections, often leaving visible drips on the bell housing or undercarriage after extended idle periods.
• Erratic gear engagement or delayed shifting caused by insufficient line pressure reaching the clutch packs, particularly under load during uphill climbs or towing.
• Elevated transmission fluid temperature exceeding normal operating range, as restricted flow through a collapsed or kinked hose pipe reduces heat exchange efficiency.
• Audible whining or cavitation noise from the pump area when the hose pipe develops internal delamination, restricting fluid volume to the torque converter.

Technical Specifications

Compatibility

This hose pipe is factory-specified for the ZF WG 260 and WG 310 series transmissions, commonly found in mid-range wheel loaders, telehandlers, and industrial tractors. It also fits select variants of the WG 180, WG 200, and WG 250 models where the cooler circuit routing matches the pre-formed bend geometry. Always verify the existing hose routing against the 4646301301: COVER and 0636015304: HEXAGON SCREW mounting points to confirm fitment. The 0501.212.309 replaces superseded part numbers 0501.212.308 and 0501.212.307.
