ZF 2095.313.021 TUBE | OEM Genuine Part

Overview

The ZF 2095.313.021 TUBE is a genuine OEM hydraulic fluid conduit engineered for the lubrication and cooling circuits within ZF heavy-duty powershift transmissions. This precision-formed steel tube directs pressurized oil from the valve body to the rotating clutch packs and planetary gear sets, ensuring consistent thermal regulation and component lubrication. As a factory-spec replacement for part number 2095.313.021, it restores original flow dynamics and prevents contamination ingress in construction machinery drivelines. This tube integrates directly with the 5838109007: DIFFERENTIAL assembly to maintain oil feed to the final drive, and its alignment is secured by the 0631329086: SPRING PIN during installation.

Symptoms of Failure

• Hydraulic oil seepage at tube junctions: Cracks or corrosion on the 2095.313.021 tube cause visible oil drips around the transmission housing, often mistaken for a pan gasket leak.
• Overheating transmission during low-speed operation: Restricted oil flow through a collapsed or blocked tube leads to elevated sump temperatures, particularly in excavators and wheel loaders.
• Erratic clutch engagement or delayed shifts: Insufficient pressure delivery to the clutch packs, often accompanied by a whining noise from the 0750117075: TAPER ROLLER BEARING due to oil starvation.
• Metal debris in transmission filter: Internal tube wall erosion sheds fine metallic particles into the circuit, accelerating wear on the 2095209019: DIFFERENTIAL gears.

Technical Specifications

Compatibility

This genuine ZF tube is primarily designed for the WG180, WG200, and WG211 series powershift transmissions used in off-highway construction equipment. It also fits select variants of the 4WG-200 and 5WG-180 torque converter transmissions. Always verify the tube routing against your specific transmission housing; the 2095.313.021 is not interchangeable with the longer tube used in WG310 models.
