Apply 5P-3413 Pipe Sealant to the threads of the sensor prior to installation. (1) Torque for the locknut ... 37 4 N m (27 3 lb ft)(2) Air Gap To adjust the air gap, use the procedure that follows:1. Align a rotor tooth on the output shaft directly in the center of the threaded sensor opening.2. Screw the speed sensor into the hole (by hand) until the end of the sensor just makes contact with the rotor tooth.3. Loosen the sensor by one-half turn (180 degrees in a counterclockwise direction). This sets the air gap to 0.71 mm (.028 inch).4. Tighten locknut (1) to a torque value of 37 4 N m (27 3 lb ft). Do not allow the sensor to turn as the locknut is tightened.
