ZF 0501.211.316 HOSE PIPE for WG260/WG310 | OEM Genuine Part

Overview

The ZF 0501.211.316 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG260 and WG310 transmission series. This OEM genuine part channels pressurized hydraulic oil between the valve body and the clutch pack assembly, ensuring precise actuation and consistent lubrication under high-torque conditions. As a direct replacement for the original equipment, the SKU 0501.211.316 maintains factory-specified flow rates and pressure tolerances, preventing internal cavitation and thermal degradation. When paired with a properly sealed TRANSMISSION HOUSING, this hose pipe guarantees uninterrupted oil circulation essential for smooth gear engagement in heavy-duty industrial applications.

Symptoms of Failure

• External hydraulic oil leaks near the transmission bell housing – Cracks or embrittlement in the hose pipe cause visible fluid seepage, often mistaken for a gasket failure. This is a common search query for “ZF WG260 oil leak at hose connection.”
• Delayed or harsh gear engagement under load – A compromised hose pipe reduces line pressure, leading to “ZF WG310 slipping in forward gears” as clutches fail to fully compress.
• Overheating transmission fluid with burnt odor – Restricted flow from a collapsed hose pipe forces the pump to work harder, generating excess heat. This symptom is frequently searched as “transmission overheating after hose replacement.”
• Erratic shift timing or neutral drops – Air ingestion through a cracked hose pipe causes spongy shift feel, a known issue for “ZF WG260 erratic shifting fix.”

Technical Specifications

Compatibility

This hose pipe is engineered for the ZF WG260 and WG310 series, but it also fits select variants of the WG180, WG200, and WG250 transmissions where the hydraulic circuit uses identical routing. Always verify the hose path against your existing assembly, as the 0501.211.316 interfaces directly with the HOUSING and the COVER on these models. For WG180 applications, confirm the COVER SHEET alignment matches the hose routing to avoid kinking. This part is not compatible with the WG120 or WG150 series due to different port configurations.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Yes, on most WG310 installations, the hose can be accessed by removing the lower cover and disconnecting the banjo fittings. However, on WG260 models with tight clearance, partial removal of the transmission housing may be required. Always replace the O-rings at both ends during installation.”

“name”: “Is the 0501.211.316 hose pipe interchangeable with aftermarket alternatives?”,
“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Only OEM genuine parts guarantee the exact inner diameter and burst pressure rating. Aftermarket hoses often use thinner wall construction, leading to flow restriction or premature failure. For critical applications, always use the ZF 0501.211.316 to maintain warranty compliance.”
