1. Raise the seat cushion to full height and a forward position on the seat rails. (Figure 1)

NOTE:

Note the rotational position of the cable end for re-assembly.

2. Remove the cable end from the seat track motor, keeping the other end engaged into the track drive gear assembly.

CAUTION:

Ensure a light grip is used as cable end is easily damaged.

3. Connect a suitable pair of locking pliers to the end of the drive cable.

4. Turn the drive cable clockwise 13 full rotations. (Figure 2)

CAUTION:

Care should be taken to ensure shaft end is inserted fully home into the seat motor shaft. Under no circumstances attempt to run motor to refit as

shaft damage will result.

5. Install the seat track drive cable into the seat track motor.

6. Test the seat movement.

^ If movement is still evident, rotate seat track drive cable clockwise one full rotation at a time. Repeat until movement no longer exists.

^ If the seat motor is noisy or very slow to operate. rotate the drive cable counter-clockwise one full rotation at a time and retest. Repeat until the

noise or slow operation no longer exists, ensuring that the drive cable is not rotated anticlockwise too much as to recreate seat movement.
