ZF 2093.317.014 AXLE FLARED TUBE | OEM Genuine Part

Overview

The ZF 2093.317.014 AXLE FLARED TUBE is a critical hydraulic and structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part serves as the primary conduit for lubricating oil between the axle housing and the differential carrier, ensuring consistent fluid flow to high-friction areas such as the bevel gear set and bearings. Manufactured to ZF’s exacting tolerances, the flared tube design prevents fluid turbulence and maintains pressure integrity under extreme loads. The SKU 2093.317.014 is specifically engineered to interface with the differential housing and the DIFF.HOUSING, forming a sealed circuit that protects internal gears from thermal damage. Without this tube, the axle assembly cannot sustain proper lubrication, leading to rapid component wear.

Symptoms of Failure

• Hydraulic oil seepage at axle tube connection: A worn or cracked 2093.317.014 tube often produces visible oil drips near the differential housing, especially after extended operation in loaders or excavators.
• Whining noise from differential during turns: When the flared tube fails to deliver adequate oil to the DIFFERENTIAL gears, metal-on-metal contact creates a high-pitched whine that intensifies under load.
• Overheating axle housing: Restricted oil flow due to a collapsed or blocked flared tube causes localized heat buildup, often detectable by discoloration of the housing paint near the tube mounting point.
• Intermittent gear lock-up or slipping: Starvation of the TAPER ROLLER BEARING set leads to erratic differential behavior, including momentary loss of traction on uneven terrain.

Technical Specifications

Compatibility

This flared tube is designed for ZF’s heavy-duty transmission and axle series commonly found in wheel loaders, graders, and dump trucks. It is a direct fit for the WG180 and WG200 power-shift transmissions, as well as the AP400 and AP500 axle ranges. The 2093.317.014 also integrates with the DIFFERENTIAL assembly in ZF’s TC-Tronic series. For applications using the 2093.317.014, always verify the tube’s flare seat matches the corresponding port on the differential housing to avoid cross-threading.

Frequently Asked Questions

Q: Can I reuse the old sealing washers when installing the 2093.317.014?
A: No. ZF recommends replacing all copper or aluminum crush washers at the tube flare connections. Reusing old seals is a leading cause of premature oil leaks around the differential housing.

Q: Does this tube require thread sealant on the mounting bolts?
A: Only if the tube uses bolt-on flanges. For the standard flared compression fitting, no sealant is needed—the 37° flare creates a metal-to-metal seal. Apply a light coat of oil to the flare nut threads to prevent galling.

Q: How do I identify a counterfeit 2093.317.014 tube?
A: Genuine ZF tubes have a laser-etched part number on the tube body, a uniform zinc-nickel finish, and a chamfered flare edge. Counterfeit parts often show rough machining marks or inconsistent wall thickness.
