Overview
This OEM genuine ZF 2093.211.055 Axle Flared Tube is a critical hydraulic and structural component engineered for heavy-duty construction machinery. Positioned within the final drive assembly, this flared tube channels high-pressure lubricant and cooling oil directly to the axle bearings and differential gears, ensuring consistent thermal regulation and friction reduction under extreme loads. The part number 2093.211.055 is precision-machined to factory tolerances, guaranteeing a leak-proof seal between the axle housing and the differential carrier. When installed alongside a 2093109049: DIFFERENTIAL and the 2093209094: DIFFERENTIAL, this tube forms the backbone of the lubrication circuit, preventing premature wear on internal rotating assemblies.
Symptoms of Failure
- Visible oil seepage at axle tube connection: A worn or cracked flared tube will allow transmission fluid to escape, often pooling near the wheel hub or differential housing.
- Elevated operating temperatures in the axle assembly: Restricted oil flow due to tube deformation causes localized overheating, detectable by infrared thermography or dashboard warning lights.
- Intermittent gear grinding during turns: Insufficient lubrication reaching the 2093109049: DIFFERENTIAL leads to metal-on-metal contact, producing a distinct whining or grinding noise.
- Contaminated oil with metallic debris: Internal tube fractures shed microscopic metal particles into the lubricant, accelerating wear on the 0750117075: TAPER ROLLER BEARING and 2093309078: DIFF.HOUSING.

Frequently Asked Questions
Q: Can I reuse the old O-ring when installing the 2093.211.055 tube?
A: No. ZF recommends always replacing the sealing O-ring (not included) to prevent leaks. The flared tube relies on a precise metal-to-metal seal; any debris on the flare face will cause immediate seepage.
Q: How do I know if this tube fits my WG200 transmission?
A: Measure the existing tube length and flare angle. The 2093.211.055 has a 285 mm length and 45° flare. If your axle uses a different flare angle (e.g., 37°), this part will not seal correctly. Cross-reference with your 2093309078: DIFF.HOUSING part number for guaranteed compatibility.
Q: What causes a flared tube to crack prematurely?
A: Common causes include over-torquing the retaining nut, vibration from a worn 0750117075: TAPER ROLLER BEARING, or thermal stress from blocked oil passages. Always inspect the 2093109049: DIFFERENTIAL for debris when replacing the tube.
