ZF 2094.247.027 TUBE | OEM Genuine Part

Overview

The ZF 2094.247.027 TUBE is an OEM genuine hydraulic fluid conduit engineered for the internal lubrication and cooling circuits within ZF heavy-duty powershift transmissions. This precision-formed tube directs pressurized oil to critical bearing surfaces and clutch packs, ensuring consistent thermal regulation and friction reduction during high-torque operation. As a factory-spec component, the SKU 2094.247.027 replaces worn or corroded tubing without requiring adapter modifications, maintaining the exact flow dynamics designed by ZF. It is typically located along the lower valve body or main shaft gallery, routing fluid between the pump outlet and the rotating clutch assemblies.

Symptoms of Failure

• Hydraulic oil seepage at transmission bell housing: A cracked or fatigued 2094.247.027 TUBE often produces slow, persistent drips that pool near the converter housing, leading to low fluid levels and eventual overheating.
• Erratic clutch engagement under load: When the tube develops internal restrictions or pinhole leaks, clutch pack pressure drops, causing delayed or harsh shifting during grading or dozing operations.
• Audible whine from transmission sump: Air ingestion through a compromised tube creates cavitation noise, particularly at idle, accompanied by foamy oil on the dipstick.
• Intermittent gear slip in reverse range: Loss of directed lubrication to the reverse clutch pack due to tube failure results in momentary power loss when backing heavy machinery.

Technical Specifications

Compatibility

This fluid tube is designed for integration into ZF WG-series powershift transmissions commonly found in construction machinery. Based on its hydraulic routing profile, the 2094.247.027 TUBE is compatible with the WG180, WG200, and WG210 transmission models. It also appears in select 4WG200 and 5WG210 variants used in wheel loaders and telehandlers. Always verify the tube’s bend geometry against your existing assembly before installation.

During replacement, the tube interfaces directly with the 2094104412 MAIN SHAFT and the 2094304054 MAIN SHAFT, which support the rotating drum assemblies. The 2094106010 SHIFT SYSTEM controls the valve timing that feeds oil through this tube, while the 2094206001 GEARSHIFT SHAFT provides the mechanical actuation path. For a complete overhaul, inspect the 2094306053 GEARSHIFT SHAFT and the 0630513070 SNAP RING for wear. The 2094306019 WASHER and both 0732040444 COMPRESSION SPRING and 0732040728 COMPRESSION SPRING ensure proper preload, while the 2093206001 BUSH supports the shaft alignment.

Frequently Asked Questions

Q: Can the 2094.247.027 TUBE be repaired if it has a small crack?
A: No. ZF does not recommend welding or patching this tube due to the risk of internal debris and altered flow characteristics. Replacement with the OEM genuine part is the only reliable solution for maintaining hydraulic integrity.

Q: How do I confirm this tube fits my WG200 transmission?
A: Visually compare the bend radius and overall length of your existing tube against the 2094.247.027. Additionally, check that the tube’s flare fittings match the port configuration on your main valve body. If in doubt, consult your transmission serial number.

Q: What other parts should I replace when installing a new tube?
A: It is prudent to replace the 0630513070 SNAP RING and 2094306019 WASHER simultaneously, as these components often suffer corrosion in the same fluid environment. Inspect the 2093206001 BUSH for ovalization before reassembly.
