when it was removed continue with step 13; if it did stay attached, skip to step14.
14. Reinstall the sensor actuator shaft (Item #5) to the gearcase cover (Item #4) by positioning the
two parts relative to each other as shown in Fig. 2. With the sensor actuator shaft pin at the 3
o’clock position and the worm gear pocket of the gearcase cover at the12 o’clock position
press them together. The parts may stay together, if not, hold them together and go on to step
14.
15. Place the gearcase cover and sensor actuator shaft assembly down onto the gearcase so the
pin on the sensor actuator shaft (Item #5) fits into the hole on the toothed end of the gear
segment (Item #8). Carefully rotate the gearcase assembly counter-clockwise until the
mounting screw holes in the cover line up with the tapped holes in the gearcase.
16. Reinstall the four cap screws and washers that secure the gear case cover (Item #’s 2 & 3).
Apply #242 Loctite to the threads and tighten to 16 in/lbs.
