19. Rotate the Geneva gear so the pin on the back of the
Geneva gear lines up with the slot in the reversing
actuator.
20. Gently push the Geneva gear toward the steel plate.
If there is resistance and the Geneva gear cannot be
pushed all the way forward into place, the neutral
switch actuator is hitting the neutral switch arm.

Do not force it into place or damage to the
neutral switch will result. Instead, insert small
screwdriver through the small hole in the steel
plate and depress the neutral switch while fully
seating the Geneva gear. See Figure 148.
21. Push the washer against the Geneva gear and use
a lineman's pliers to install the e-clip into the e-clip
groove on the main shaft. See Figure 149.

22. Push the shaft the remainder of the way through the
hole in the steel plate. Secure the steel shaft to the
steel panel using the 1/2" -13 lock nut. Use a 5/8" open
end wrench to hold the steel shaft while securing the
nut on the threaded end of the shaft with a 3/4" socket
wrench. Tighten the nut to a torque of 180 to 400 in-lbs
(20.3–45.2 Nm). Refer to Figure 150.
23. Rotate the movable contact insulator arm so the only
one of the movable contacts is engaging the neutral
stationary contact as shown in Figure 151. This should
line the arm up with the Geneva gear so that the
actuator finger pocket in the arm is across from the bolt
holes used to attach the finger to the Geneva gear.
