Overview
The ZF 2093.317.028 AXLE FLARED TUBE is a precision-engineered hydraulic conduit designed to deliver pressurized lubricant and cooling fluid directly to the differential 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 the 2093109024: DIFFERENTIAL and the 2093209095: DIFFERENTIAL unit. Manufactured to ZF’s exacting tolerances, the SKU 2093.317.028 features a flared end design that creates a vibration-resistant, leak-proof connection under extreme torque loads. Without this tube, the axle assembly cannot maintain proper lubrication, leading to rapid wear of internal gears and bearings.
Symptoms of Failure
- Hydraulic fluid seepage at axle connection points: A cracked or corroded flared tube will cause oil to weep from the joint, leaving visible stains on the axle housing and transmission bell housing.
- Intermittent gear grinding during low-speed maneuvering: When the tube becomes partially blocked by debris or internal corrosion, oil starvation to the 0750117075: TAPER ROLLER BEARING results in metal-on-metal contact and audible grinding noises.
- Overheating differential housing: A restricted flared tube reduces oil flow, causing the 2093309071: DIFF.HOUSING to exceed normal operating temperatures by 20-30°C.
- Premature bearing failure in the axle assembly: Insufficient lubrication from a compromised tube accelerates wear on the taper roller bearings, often requiring complete axle overhaul within 500 operating hours.

Compatibility
This axle flared tube is engineered for ZF’s WG180, WG200, and WG250 series powershift transmissions commonly found in wheel loaders, excavators, and telehandlers. It directly interfaces with the 2093109024: DIFFERENTIAL and 2093209095: DIFFERENTIAL assemblies. The tube also fits ZF APL-300 and APL-350 series axles used in articulated dump trucks. Always verify your transmission serial number against ZF’s compatibility chart before installation.

Frequently Asked Questions
Q: Can I install this flared tube without replacing the O-rings?
A: No. ZF recommends always replacing the sealing O-rings (sold separately) when installing a new 2093.317.028 tube to guarantee a leak-free seal under high-pressure operation.
Q: How do I identify if my machine uses this specific tube?
A: Measure the existing tube’s outer diameter and length. The 2093.317.028 has an 18 mm OD and 285 mm length. Also check for the ZF logo stamped near the flare end.
Q: What torque should be applied to the tube nut during installation?
A: Tighten the flare nut to 45 Nm (33 ft-lb) using a crowfoot wrench. Over-torquing can deform the flare and cause leaks.
