(3) Using palm of the hand, firmly push and rotate the actuator approximately 30 degrees clockwise until
the actuator flange contacts the fuel pump body.
(4) Rotate the actuator counterclockwise until the mounting holes are aligned.
(5) Install the capscrews (1, FIGURE 3-12). These capscrews have captive spring washers and do not
require lockwashers. Tighten the capscrews until they are finger tight.
(6) Tighten the actuator capscrews as follows:
(a) Starting with the bottom capscrew, tighten each capscrew 1/8 of a turn until it is seated.
(b) Tighten the capscrews in a clockwise sequence to 25 in-lb. (2.8 N ) torque.
m
(c) Tighten in sequence to 50 in-lb. (5.6 N ) torque.
m
(d) Now, loosen all three capscrews completely.
(e) Tighten the capscrews again using the same procedure described above. This procedure
should keep the actuator from binding.
CAUTION
This test will only verify that the actuator will go from the full open to the full closed
position. A slight binding of the actuator shaft can cause a governor stability
problem. This test may not detect a slight binding.
(7) A final check is to apply and remove battery voltage across the two actuator terminals. You should
hear the actuator as it opens and closes. If the actuator sounds as if it is not operating, or is
operating too slowly, loosen all capscrews and tighten them again as described in step (6) of this
procedure.
e. Install the fuel pump on the engine (paragraph 2-33).
