ZF 2093.247.058 TUBE | OEM Genuine Part

Overview

The ZF 2093.247.058 TUBE is an OEM genuine fluid transfer conduit engineered for the lubrication and cooling circuits within heavy-duty ZF construction machinery transmissions. This precision-formed tube directs pressurized oil to critical differential and bearing assemblies, ensuring consistent thermal regulation and component lubrication under extreme load. As a factory-specified replacement, the SKU 2093.247.058 is machined to exact OEM tolerances to prevent pressure loss and maintain hydraulic integrity. It sits within the lower valve body-to-differential oil gallery, bridging the main control unit to the rotating assembly.

Symptoms of Failure

• Visible oil seepage around transmission housing: A cracked or corroded 2093.247.058 tube will cause gradual ATF leakage, often pooling near the differential mounting flange.
• Intermittent gear slippage under load: Insufficient lubrication from a compromised tube leads to momentary torque loss, especially during heavy digging or grading operations.
• Overheating transmission fluid: Restricted oil flow through a deformed or blocked tube reduces cooling capacity, triggering thermal warnings on the machine dashboard.
• Unusual whining noise from differential area: Starved bearings due to tube failure produce a high-pitched metallic sound that intensifies with engine RPM.

Technical Specifications

Compatibility

This tube is designed for ZF WG series powershift transmissions commonly used in wheel loaders, graders, and excavators. It is a direct fit for the WG180, WG200, and WG211 models. The 2093.247.058 also integrates with the WG150 and WG250 series when used in conjunction with the correct differential housing. Always verify the tube routing against your specific transmission serial number before installation.

During replacement, it is common to inspect and replace adjacent wear items. The 2093109008 DIFFERENTIAL and 2093209096 DIFFERENTIAL assemblies rely on this tube for proper oil delivery. Additionally, the 0750117075 TAPER ROLLER BEARING and 2093309073 DIFF.HOUSING should be evaluated for wear whenever the tube is replaced, as debris from a failed tube can damage these components.

Frequently Asked Questions

Q: Can a damaged 2093.247.058 tube cause transmission failure?
A: Yes. A ruptured tube will rapidly deplete transmission fluid, leading to catastrophic bearing and gear failure. Immediate replacement is recommended upon detecting any oil residue near the tube.

Q: Is the 2093.247.058 tube interchangeable with other ZF part numbers?
A: No. This tube has a specific bend radius and end fitting geometry unique to the 2093 series. Substituting with a non-OEM tube can cause improper oil flow and eventual transmission damage.

Q: What torque should be applied to the tube fittings during installation?
A: ZF specifies 25 Nm for the banjo bolt connections. Over-tightening can deform the tube sealing surface, while under-tightening may cause vibration-induced loosening.
