Overview
The ZF 2093.211.029 AXLE FLARED TUBE is a precision-engineered hydraulic conduit designed to deliver pressurized lubricant and cooling oil directly to the differential and axle assembly in heavy-duty construction machinery transmissions. This OEM genuine part, identified by SKU 2093.211.029, sits between the transmission housing and the axle carrier, forming a sealed connection that ensures consistent oil flow to critical rotating components. Constructed from high-strength steel with a flared end fitting, this tube resists vibration fatigue and thermal expansion common in loader and dozer applications. When paired with a 2093109028: DIFFERENTIAL and the 2093209094: DIFFERENTIAL assembly, this tube guarantees uninterrupted lubrication to the gear set.
Symptoms of Failure
- Hydraulic oil seepage at axle connection: A cracked or corroded flared tube will allow transmission fluid to weep from the joint, leaving visible puddles under the machine after shutdown.
- Intermittent gear whine or chattering: Insufficient oil delivery due to a restricted or collapsed tube causes the 0750117075: TAPER ROLLER BEARING to run dry, producing a high-pitched noise during turns or under load.
- Overheating differential housing: A blocked tube starves the 2093309078: DIFF.HOUSING of cooling oil, leading to thermal damage and premature seal failure.
- Reduced traction or wheel slip: Oil starvation to the differential clutch pack causes erratic engagement, making the machine feel sluggish on inclines.

Compatibility
This flared tube is engineered for ZF’s heavy-duty powershift transmission families commonly found in wheel loaders, graders, and articulated dump trucks. It directly fits the following ZF models: WG180, WG200, WG211, and WG250. It also integrates with the 4WG-200 and 5WG-250 series. Always verify your transmission serial number before ordering, as minor revisions exist for early WG180 units. The tube is a direct replacement for the original equipment part and requires no adapter fittings.

Frequently Asked Questions
Q: Can I reuse the old O-rings when installing the 2093.211.029 tube?
A: No. Always replace the sealing washers and O-rings. The flared tube relies on a metal-to-metal seal at the flare cone; old seals will cause immediate weeping.
Q: Will this tube fit a ZF 4WG-200 transmission from a 1998 model?
A: Yes, the 2093.211.029 is backward-compatible with all 4WG-200 units produced after 1995. Verify the tube routing matches your chassis to avoid interference with the brake lines.
Q: What torque should I apply to the tube nuts?
A: Tighten the union nuts to 45 Nm (33 ft-lbs). Over-torquing can distort the flare and cause leaks. Use a crowfoot wrench to access the rear nut on the differential housing.
