Overview
The ZF 2094.247.025 TUBE is a precision-engineered hydraulic fluid conduit designed for the lubrication and cooling circuits within heavy-duty ZF construction machinery transmissions. This OEM genuine part, identified by SKU 2094.247.025, routes pressurized oil to critical bearing surfaces and gear meshes, ensuring consistent thermal regulation and component lubrication. Positioned between the transmission housing and the valve body, this tube assembly maintains the structural integrity of the fluid delivery system under extreme operating pressures. When paired with a properly functioning 5838109012: DIFFERENTIAL, it ensures balanced oil distribution across the entire drivetrain.
Symptoms of Failure
- Hydraulic fluid seepage at tube fittings: Cracks or corrosion in the 2094.247.025 TUBE often cause visible oil drips near the transmission bell housing, leading to low fluid levels and eventual overheating.
- Erratic gear engagement under load: A compromised tube reduces lubrication pressure, causing delayed clutch pack engagement and harsh shifting during excavation or grading operations.
- Elevated transmission operating temperatures: Restricted oil flow through a damaged tube prevents proper cooling, triggering thermal warnings on construction machinery dashboards.
- Metallic debris in transmission fluid: Insufficient lubrication from a failing tube accelerates wear on the 0750117075: TAPER ROLLER BEARING, generating particulate contamination.

Compatibility
This tube is engineered for ZF’s WG series powershift transmissions commonly used in wheel loaders, dozers, and telehandlers. It is a direct replacement for units in the WG180, WG200, and WG210 series. The 2094.247.025 TUBE also integrates with the 2093209023: DIFFERENTIAL assembly in articulated dump trucks. For final drive applications, it connects to the 5838300626: DIFFERENTIAL HOUSING to maintain oil flow integrity.

Frequently Asked Questions
Q: Can the 2094.247.025 TUBE be repaired if it develops a pinhole leak?
A: No. This tube is a single-piece hydraulic line. Welding or patching compromises its pressure rating. Replacement with the OEM genuine part is mandatory to prevent catastrophic fluid loss.
Q: How does this tube interact with the 0750117075 TAPER ROLLER BEARING?
A: The tube delivers pressurized oil directly to the bearing’s lubrication gallery. Without proper flow from the 2094.247.025, the taper roller bearing experiences rapid spalling and seizure.
Q: Is this part compatible with ZF WG180 transmissions built before 2010?
A: Yes. The 2094.247.025 TUBE uses the same mounting flange pattern and O-ring boss dimensions across all WG180, WG200, and WG210 variants from 2005 onward.
