10. Remove the orbital cam from the motor shaft. Now you are ready to
remove the input orbital motor.
11. Unplug the Molex motor cable J-12. The end of this connector is
located under the main plate and will not fit through the main plate
hole. Remove the four pins in the connector to free the cable. Note the
wire colors and positions in the connector (see Figure 7-9).
12. Use a Molex pin extractor tool to remove the four pins from the white
plastic connector.
13. After removing the four pins, pull the cable through the main plate.
14. From below the main plate, remove the four 1/16-inch hex screws
that hold the input orbital motor to the main plate.
15. Lower the main plate and remove the input orbital motor.
16. Place the new input orbital motor in position on the main plate. Make
sure the power cable is oriented to the right side of the new input
orbital motor.
17. Guide the motor cable through the hole in the main plate.
18. Insert the four motor wires into the white plastic Molex connector. Be
sure to insert the wires in the same order (and orientation) as shown
in Figure 7-9.
19. The input orbital motor shaft has one flat side. Turn the shaft until the
flat edge faces the front of the 2500.
20. The orbital cam has a small hole on its outer edge. Position the cam
on the motor shaft so this small hole is positioned on the right side
(input side) of the shaft.
CAUTION: As you reinstall the input orbital assembly, make sure the
white bushing that fits over the spindle stays in position.
21. Reinstall the input orbital assembly (in reverse order from the
procedure in steps 6-9 above).
22. Reinstall the front and rear orbital alignment blocks.
