ZF 2093.211.024 AXLE FLARED TUBE | OEM Genuine Part

Overview

The ZF 2093.211.024 AXLE FLARED TUBE is a precision-engineered hydraulic conduit designed to deliver pressurized lubricant and cooling oil directly to the differential and axle assembly within heavy-duty construction machinery transmissions. This OEM genuine part sits between the transmission housing and the axle carrier, forming a critical sealed pathway that ensures consistent oil flow to high-friction components such as the 2093109028 DIFFERENTIAL and the 0750117075 TAPER ROLLER BEARING. Manufactured to ZF’s exacting tolerances, the SKU 2093.211.024 features a flared end design that creates a leak-proof seal under high-pressure operating conditions, preventing contamination and maintaining proper lubrication across the entire axle assembly.

Symptoms of Failure

• Visible oil seepage around axle tube connections: When the flared sealing surface degrades or cracks, hydraulic oil escapes at the junction between the tube and the 2093309078 DIFF.HOUSING, leaving telltale drips on the undercarriage.
• Intermittent gear slippage under load: Insufficient oil delivery due to a restricted or leaking tube starves the 2093209094 DIFFERENTIAL of lubrication, causing momentary loss of torque transfer during heavy excavation.
• Elevated operating temperatures in the axle housing: A compromised tube reduces oil flow, leading to thermal buildup that accelerates wear on internal gears and bearings.
• Metallic debris in the transmission fluid: As the tube fails, particulate contamination from the axle can migrate into the main transmission circuit, damaging pumps and valves.

Technical Specifications

Compatibility

This flared tube is engineered for ZF’s heavy-duty powershift transmission families commonly deployed in wheel loaders, graders, and dozers. It is a direct fit for the WG180, WG200, and WG210 series, as well as the 4WG-180 and 4WG-200 variants. The tube also integrates with the 6HP and 8HP automatic transmission ranges used in off-highway applications. Always verify your transmission model’s axle housing configuration before ordering.

Frequently Asked Questions

Q: Can I reuse the old sealing washers when installing the 2093.211.024 tube?
A: No. ZF recommends always replacing the copper or aluminum sealing washers at both ends of the flared tube to guarantee a leak-free joint. Reusing old washers can lead to immediate oil seepage and potential tube misalignment.

Q: How do I know if this tube fits my ZF WG200 transmission?
A: Check the axle housing casting number near the differential input flange. The 2093.211.024 tube is designed for housings with a 18 mm port and a 45° flare seat. If your housing uses a 22 mm port, you will need the corresponding larger tube variant.

Q: What torque specification should I use for the tube nut?
A: Tighten the flare nut to 45 Nm (33 ft-lb) using a crowfoot wrench. Over-torquing can distort the flare and cause internal cracking; under-torquing will result in oil leaks under pressure.
