Component Code(s) 4334SUBJECT: 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.
