Overview
The ZF 2094.347.031 FLANGE is a critical OEM genuine component engineered for the output or input connection points within heavy-duty ZF powershift transmissions. This flange serves as the primary interface between the transmission housing and the driveline, ensuring precise torque transfer and secure coupling to the drive shaft. Commonly found in construction machinery such as wheel loaders, graders, and telehandlers, the SKU 2094.347.031 is machined to exacting tolerances to prevent vibration and misalignment. It is often mounted directly onto the 2094104412: MAIN SHAFT or the 2094304054: MAIN SHAFT, forming a robust assembly that withstands high cyclic loads in demanding off-road environments.
Symptoms of Failure
- Oil seepage at the flange joint: A worn or cracked 2094.347.031 flange often leads to transmission fluid leaking past the seal, leaving visible drips on the bell housing or under the machine.
- Driveline vibration during gear engagement: When the flange loses its concentricity, operators may notice pronounced shuddering or shaking, especially when shifting under load.
- Premature bearing or seal wear: A distorted flange places excessive lateral stress on adjacent components, accelerating failure of the 2094106010: SHIFT SYSTEM and the 2094206001: GEARSHIFT SHAFT.
- Intermittent power loss or slipping: A loose flange can cause the drive shaft to disengage momentarily, resulting in a temporary loss of tractive effort during heavy pushing or grading operations.

Frequently Asked Questions
Q: Can the ZF 2094.347.031 flange be reused after removal?
A: It is not recommended. The flange is a precision-machined component that can distort during removal. Reusing it often leads to oil leaks and driveline imbalance. Always install a new OEM genuine part.
Q: What torque specification is required for the flange retaining nut?
A: Typical tightening torque for this flange on a WG200 transmission is 350–400 Nm, but always consult your specific ZF service manual. Over-torquing can crack the flange hub.
Q: Does this flange fit both input and output shafts?
A: The 2094.347.031 is primarily designed for output shaft applications. For input shaft mounting, verify spline count and pilot diameter. It is commonly paired with the 2094104412: MAIN SHAFT for output duty.
