Overview
The ZF 2094.247.020 TUBE is an OEM genuine fluid transfer conduit engineered for the hydraulic and lubrication circuits within ZF heavy-duty construction machinery transmissions. This precision-formed tube directs pressurized oil to critical clutch packs and bearing assemblies, ensuring consistent cooling and actuation. As a factory-spec component, it guarantees exact fitment and flow characteristics. The part number 2094.247.020 is your direct replacement for the original assembly line component. It integrates directly with the 2094101012: TRANSMISSION HOUSING, routing fluid from the main pump gallery to the upper valve body.
Symptoms of Failure
- External hydraulic oil leaks near the transmission housing: Cracks or fatigue at the tube ends cause visible drips, often mistaken for a failed seal.
- Intermittent gear slipping under load: A compromised tube reduces clutch apply pressure, leading to hesitation or slipping during excavation or grading.
- Overheating transmission fluid: Restricted flow from a deformed or blocked tube starves the oil cooler circuit, triggering thermal alarms.
- Low transmission pressure codes: Diagnostic scans show pressure drops in specific clutch circuits, traceable to a ruptured or loose tube.

Compatibility
This tube is primarily specified for ZF WG180, WG200, and WG210 series powershift transmissions used in wheel loaders, dozers, and telehandlers. It also fits select Ecomat 4HP and 6HP models where the auxiliary hydraulic circuit requires a rigid steel line. Always verify the tube routing against the 2094301036: HOUSING and the 2094298057: HOUSING to confirm correct alignment. The 2094301071: COVER must be removed for access during installation.
