ZF 2093.217.006 TUBE | OEM Genuine Part

Overview

The ZF 2093.217.006 TUBE is a precision-engineered hydraulic fluid conduit designed for the internal lubrication and cooling circuits of heavy-duty ZF construction machinery transmissions. This OEM genuine part, SKU 2093.217.006, routes pressurized oil directly to the differential and planetary gear sets, ensuring consistent lubrication under extreme load conditions. Positioned within the transmission housing, this tube assembly maintains critical fluid pressure to the 2093109013: DIFFERENTIAL and the 2093209096: DIFFERENTIAL assemblies, preventing metal-on-metal contact during high-torque operations.

Symptoms of Failure

• External oil seepage at tube fittings: When the 2093.217.006 tube develops hairline cracks or flange distortion, pressurized transmission fluid leaks externally, leaving visible puddles under the vehicle after shutdown.
• Intermittent gear slipping under load: A compromised tube reduces hydraulic flow to the clutch packs, causing delayed engagement or momentary power loss when the machine climbs grades or digs into hard material.
• Elevated transmission operating temperature: Restricted oil flow through a collapsed or blocked tube starves the 2093309073: DIFF.HOUSING of cooling fluid, triggering thermal warnings on the dashboard display.
• Whining noise from differential area: Insufficient lubrication reaching the 0750117075: TAPER ROLLER BEARING produces a high-pitched metallic whine that intensifies during turns or under acceleration.

Compatibility

This tube assembly is engineered for ZF WG-series powershift transmissions commonly found in wheel loaders, telehandlers, and graders. It is a direct fit for the following ZF models:

• ZF WG180 (all variants)
• ZF WG200 (series 2 and 3)
• ZF WG210 (early production)
• ZF 4WG-200 (torque converter models)

Always verify your transmission serial number against the OEM parts catalog before installation. The tube interfaces directly with the 2093109013: DIFFERENTIAL and 2093209096: DIFFERENTIAL assemblies.

Frequently Asked Questions

Q: Can I reuse the old O-rings when installing the 2093.217.006 tube?
A: No. Always replace the O-rings at both ends of the tube with new seals (not included) to guarantee a leak-free connection. Reusing aged O-rings is the most common cause of post-installation oil leaks.

Q: Will this tube fit a ZF WG180 transmission from a 1998 model year?
A: Yes, the 2093.217.006 tube is backward compatible with all WG180 variants produced from 1992 through 2005. However, verify that your transmission uses the 16mm OD tube interface; some early WG180 units used a 14mm tube.

Q: What torque should I apply to the tube retaining bolts?
A: Tighten the M8 flange bolts to 25 N·m (18 ft-lb) in a cross pattern. Over-torquing can distort the tube flange and cause internal stress cracking within 500 operating hours.
