ZF 2093.209.027 AXLE FLARED TUBE | OEM Genuine Part

Overview

The ZF 2093.209.027 AXLE FLARED TUBE (SKU: 2093.209.027) is a critical hydraulic and structural component within ZF heavy-duty drivetrains. This OEM genuine part serves as the primary conduit for pressurized lubricant between the axle housing and the differential assembly. Positioned directly adjacent to the 2093109003: DIFFERENTIAL, the flared tube ensures consistent oil flow to the planetary gears and bearings under extreme load conditions. Manufactured from high-tensile steel with precision-formed flare ends, this part maintains a leak-proof seal even when exposed to the thermal expansion and vibration common in construction machinery. Its robust design directly supports the longevity of surrounding components such as the 0750117075: TAPER ROLLER BEARING by preventing oil starvation.

Symptoms of Failure

• Hydraulic fluid seepage at axle connection points: A worn or cracked flared tube often manifests as slow oil drips near the differential housing, leading to low lubricant levels and eventual gear damage.
• Erratic gear engagement under load: When the tube fails to deliver adequate oil pressure to the 2093209096: DIFFERENTIAL, operators may notice delayed or harsh shifting during excavation or grading operations.
• Visible tube deformation or cracking: Physical inspection may reveal stress fractures or flattened sections along the tube body, often caused by debris impact or improper installation torque.
• Overheating in the final drive area: Restricted oil flow through a damaged tube can cause localized heat buildup, accelerating wear on the 2093309073: DIFF.HOUSING and adjacent bearings.

Technical Specifications

Compatibility

This genuine ZF flared tube is engineered for use in the following transmission and axle models commonly found in wheel loaders, graders, and telehandlers: ZF WG180, WG200, WG211, and AP400 series. It is a direct replacement for the oil feed line in both single-reduction and planetary hub reduction axles. The part interfaces specifically with the 2093109003: DIFFERENTIAL and the 2093309073: DIFF.HOUSING assemblies. Always verify axle serial number before ordering.

Frequently Asked Questions

Q: Can I reuse the old O-rings when installing the 2093.209.027 tube?
A: No. Always replace all sealing washers and O-rings. The flared tube relies on a fresh metal-to-metal or O-ring seal to prevent leaks under high pressure. Reusing old seals is a common cause of premature failure.

Q: Does this tube fit ZF WG180 axles with wet brakes?
A: Yes, the 2093.209.027 is compatible with WG180 axles equipped with wet disc brakes. However, verify that your axle uses a 45° flare fitting, as some early models used a 37° JIC flare.

Q: What torque should I apply to the tube nut?
A: Tighten the flare nut to 45-50 Nm (33-37 ft-lbs). Over-torquing can distort the flare seat and cause leaks. Use a torque wrench and anti-seize compound on the threads.
