5. Press the top pinion o-ring into the inset around the top of the pinion then install the flange bearing and top
pinion washer (Fig. 9.6). Use a pair of circlip pliers to install the pinion circlip (Fig. 9.7) Be careful not to
expand the circlip too much as it may be damaged if over expanded.
6. Assemble the actuator stop screws by threading the stop nut onto the stop bolt and fitting the stop o-ring into
the groove on the stop nut.
7. Using the proper sized crescent wrench on the pinion, rotate the pinion to the (actuator) closed position. Check
the cam to make sure of correct orientation before threading in the closed limit stop until it touches the pinion
cam. Tighten the locknut to secure the stop in place. This will ensure that the cam remains in the correct
orientation during the installation process.
