Overview
This genuine OEM ZF 2093.247.067 TUBE is a critical fluid routing component within the transmission lubrication and cooling circuit. Designed for heavy-duty construction machinery, this tube ensures precise delivery of hydraulic oil to key bearing and gear interfaces, preventing thermal degradation and component scoring. The part number 2093.247.067 is engineered to exact OEM tolerances, guaranteeing a leak-free seal under high-pressure operating conditions. It sits between the transmission housing and the valve body, acting as a rigid conduit that replaces flexible hoses in high-vibration environments.
Symptoms of Failure
- External oil seepage near the transmission bell housing: A cracked or corroded 2093.247.067 tube will cause visible oil drips, often mistaken for a main seal leak.
- Erratic gear engagement or delayed shifting: Insufficient oil flow due to a blocked or deformed tube starves the clutch packs, leading to harsh or delayed shifts in WG-series transmissions.
- Overheating transmission fluid: A restricted tube disrupts the oil cooler circuit, causing the transmission to run 15-20°F hotter than normal under load.
- Low transmission fluid level without visible external leaks: Internal tube fractures can allow oil to bypass into the torque converter housing, mimicking a pump failure.

Compatibility
This tube is specifically designed for ZF WG180, WG200, and WG211 powershift transmissions used in construction machinery such as wheel loaders, graders, and telehandlers. It is also compatible with select ZF 4WG-200 and 6WG-200 variants. Always verify the transmission serial number against the OEM parts catalog before installation.
Related Components
When replacing the 2093.247.067 tube, it is recommended to inspect and replace associated driveline components. The 2093109018 DIFFERENTIAL and 2093209023 DIFFERENTIAL share the same lubrication circuit. The 0750117075 TAPER ROLLER BEARING supports the differential pinion shaft, while the 5838300626 DIFFERENTIAL HOUSING encloses the entire assembly.

Frequently Asked Questions
Q: Can I use a universal steel tube instead of the ZF 2093.247.067?
A: No. This tube has specific bend radii and flare fittings that match the transmission housing. Generic tubes will not seal properly and may cause oil starvation.
Q: How do I verify if this tube is clogged?
A: Remove the tube and blow compressed air through it. A clean tube should pass air freely. If resistance is felt, replace it immediately to avoid transmission damage.
Q: Does this tube require any special tools for installation?
A: Only standard flare nut wrenches (12 mm and 14 mm) are needed. Do not use open-end wrenches as they can round the fittings.
