SUBJECT: Steering Column Harness Assembly Kinking on G/GII Medium Wheel Loaders

PROBLEM:

A kink can occur in the 118-2943 Steering Column Harness Assembly when the steering column is tilted forward (refer to Illustration 1). This kink can cause pinched or broken wires, resulting in inoperative Forward/Neutral-Reverse or Upshift/Downshift functions.

SOLUTION:

Implement an additional loop on the 118-2943 Steering Column Harness Assembly as shown in Illustration 3 through Illustration 5. An assembly process change has been planned in order to implement this improvement on production machines.

Illustration 1. Existing routing.

Illustration 2. Existing routing ? kink may occur near item 1.

Illustration 3. Improved harness routing.

Illustration 4. Steering column with harness kink.

Illustration 5. Improved installation with a loop in harness.
