GEARCASE ROTATION INSTRUCTIONS

(Please refer to Fig. 1 and 2 of this document)

1. Disconnect harness from position sensor (Item #1) if required.

2. Check that the position sensor is rotated to the maximum allowed clockwise position and that

the screw is tight to lock it in place. Re-adjust sensor if needed.

3. Remove the four cap screws and washers that retain the gearcase cover (Item #’s 2 & 3)

4. Remove the gearcase cover (Item #4). The sensor actuator shaft (Item #5) should come off

with the cover if not remove it also.

5. Make note of the position of the gear segment (Item #8) relative to the gearcase (Item #11) you

will be rotating these two items the same amount and in the same direction; when done, they

should be in the same relationship to each other as they are now. Having a sketch or digital

photo can help insure the parts get put back in the correct relationship to each other. Parts that

are put back together incorrectly can damage the position sensor (Item #1).

6. Remove the bolt and washer (Item #’s 6 & 7) that retain the gear segment (Item #8).

7. Remove the gear segment (Item #8). It may be necessary to rotate the worm (Item #9) slightly

back and forth using a wrench on the hex end of the worm gear shaft (Item #12) while

removing the gear segment.

8. Remove the four cap screws (Item #10) that secure the gearcase (Item #11) to the valve body.

9. Rotate the gearcase to its new position. It can be rotated in 45 degree increments. Make sure

the actuator shaft, the square shaft sticking up in the middle of the gearcase, does not rotate

with the gearcase. It should stay in its original position.

10.Reinstall the four cap screws (Item #10) that secure the gearcase (Item #11) to the valve body.

Apply #242 Loctite to the threads of the four screws and tighten them in an “X” pattern to 55-60

in/lbs.

11.Reinstall the gear segment (Item #8). It may be necessary to rotate the worm (Item #9) slightly

back and forth using a wrench on the hex end of the worm gear shaft (Item #12) while

reinstalling the gear segment. Be sure that the position of the gear segment (Item #8) relative

to the gearcase (Item #11) is correct. Refer to sketch or digital photo from step 4.

12.Reinstall the bolt and washer (Item #’s 6 & 7) that retain the gear segment (Item #8). Apply

#242 Loctite to the threads and tighten to 5-7 ft/lbs.
