Cummins/Onan TGHAA — GOVERNOR ROD AND ACTUATOR

For the Cummins/Onan TGHAA.

Procedure

Disconnect the governor rod from the actuator arm if it has not already been removed.
Loosen the throttle stop screw locknut and back the screw out away from the tang on the throttle lever while gently rotating the throttle le- ver counterclockwise as far as if will go.
While holding the throttle lever counterclock- wise as far as it will go, turn the stop screw in until it just touches the tang. Then turn the screw an additional 1/8-1/4 turn (clockwise) and set and seal the locknut. If the throttle stop screw adjustment is okay, recon- nect the governor rod as follows:
Insert the rod in the spring such that the shorter hook wire is on the throttle side.
Hook the rod and spring into the grommet in the throttle lever. (The spring should pull on one side and the rod push on the other side of the grommet when fully assembled.)
Pull the governor rod towards the plastic clip on the end of the actuator lever as far as the throttle stop screw permits. Leave the actuator lever in its fully counterclockwise (rest) posi- tion. Snap the dogleg on the end of the rod into the slot in the clip that most closely lines up with it. Use both hands so as not to bend the actua- tor lever.
Hook the spring into the slot in the end of the actuator lever. When assembled, the spring hook wires should not wrap around the gover- nor rod.
Move the actuator back and forth through its full movement to make certain there is no sticking or binding.
After installing the top panel, hook the spark plug cable with the clip inside the panel to keep it from interfering with the governor rod. GOVERNOR SPRING
