Magnetic Pickup (MPU) (1) Air gap (2) Locknut

This adjustment procedure is used to repair the magnetic pickup.

1. Remove the magnetic pickup from the flywheel housing. Remove all debris from the tip of the magnetic pickup. Align the ring gear tooth directly in the center of the threaded opening.

2. By hand, screw the pickup into the hole until the end of the pickup just makes contact with the gear tooth.

3. In a counterclockwise direction, turn the pickup three-fourths of a turn. The pickup should be turned 270 degrees in the counterclockwise direction.

4. Tighten the locknut (2) to 25 ± 5 N·m (18 ± 4 lb ft).

Note: Do not allow the pickup to turn as locknut (2) is tightened.
