ZF 0501.223.087 HOSE PIPE for WG260 | OEM Genuine Part

Overview

The ZF 0501.223.087 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 260 and WG 310 transmission series. This OEM genuine part channels pressurized hydraulic oil between the valve body and the cooler circuit, ensuring consistent lubrication and thermal regulation within the transmission assembly. The SKU 0501.223.087 is designed to withstand high-temperature oil exposure and continuous vibration, maintaining a leak-free seal under demanding industrial operating conditions. When installed alongside a TRANSMISSION HOUSING, this hose pipe completes the essential hydraulic loop that governs clutch engagement and torque converter cooling.

Symptoms of Failure

• Hydraulic fluid seepage at connection points – Cracked or swollen hose pipe material often leads to visible oil drips near the transmission housing, particularly during cold starts or after extended operation.
• Erratic gear engagement or delayed shifting – A compromised hose pipe reduces line pressure, causing sluggish shifts or unexpected gear slippage in WG260 and WG310 units.
• Overheating transmission fluid – Restricted flow through a collapsed or internally damaged hose pipe prevents adequate cooling, triggering thermal warnings or fluid degradation.
• Audible whining from the pump circuit – Air ingestion through a cracked hose pipe creates cavitation noise, often accompanied by foamy fluid on the dipstick.

Technical Specifications

Compatibility

This hose pipe is factory-specified for the ZF WG 260 and WG 310 series transmissions, commonly found in heavy-duty trucks, construction loaders, and agricultural tractors. It also retrofits to WG180 and WG200 models when used with the appropriate HEXAGON SCREW and CAP SCREW kits. For proper sealing, always pair this hose with a COVER SHEET to prevent debris ingress at the connection ports. Verify your transmission serial number against ZG/WSG application charts before installation.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Yes, the 0501.223.087 is compatible with WG180 models when used with the correct hexagon screw and cap screw hardware. However, always verify the routing path and overall length against your specific transmission variant to avoid interference with the cover sheet or housing.”

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Genuine ZF parts carry the ZF logo and part number 0501.223.087 embossed on the hose body. The reinforced rubber construction should show consistent wall thickness and no surface porosity. Counterfeit parts often lack the textile braid layer and have irregular crimp fittings.”
