Setting the Actuator
1. Remove the bolt from the control linkage
2. With the control linkage pushed against the idle
stop, begin to make adjustments to the actuator link-
age in order to align the bearing of the spherical rod
end with the control linkage bolt hole. When making
linkage adjustments, thread the spherical rod end
and threaded rod evenly (for every turn of spherical
rod end, turn the threaded rod.)
DURING THIS PROCEDURE IT’S VERY IMPORTANT TO KEEP THE
CONTROL LINKAGE PUSHED AGAINST THE STOP.
3. Once the adjustments have been made to align the
spherical rod end bearing with the control linkage
bolt hole, lengthen the actuator linkage by continu-
ing to turn the spherical rod end and threaded rod 2-
2 ½ turns (1-1 ¼ turns of spherical rod end and 1-1
¼ turns of threaded rod.) This will provide 1/8” (3
mm) preload.
Use a measuring device to ensure the preload is
approximately 1/8” (3 mm), then secure the actuator
linkage to the control linkage with original bolt and
nut. Make sure the spherical ball is seated in the
control linkage bolt hole.
Tighten the 2 nuts on the threaded rod of the actua-
