3. Rotate the governor lever and shaft
counterclockwise until it stops. Use only enough
pressure to hold it in that position.
4. Check how the end of the thrott le linkage aligns
with the bushing hole in the governor lever. See
Figure 5-26. It should fall in the center of the hole.
If it doesn't, perform the adjustment procedure as
follows.
Figure 5-26. Throttle Link in Center of Hole.
B. Setting the Initial Adjustment
1. Check the split where the clamping screw goes
through the governor lever. See Figure 5-27.
There should be a gap of at least 1/32 in. If the
tips are touching and there is no gap present, the
lever should be replaced. If not already installed,
position the governor lever on the cross shaft , but
leave the clamping screw loose.
Figure 5-27. Checking Split of Clamp.
2. Follow the instructions in Step 2 of Checking the
Initial Adjustment, then reatt ach the thrott le
linkage to the governor lever with the bushing
clip. It is not necessary to reatt ach the damper or
governor springs at this time.
3. Insert a nail or Allen wrench into the hole in the
top of the cross shaft . Using light pressure, rotate
the governor shaft counterclockwise as far as it
will turn, then torque the hex nut on the
clamping screw to 6.8 N·m (63 in. lb.). See Figure
5-28. Make sure that the governor arm has not
twisted up or down aft er the nut has been
tightened.
Figure 5-28. Adjusting Governor Shaft.
4. Verify that the governor has been set correctly.
With the linkage still retained in the Full Thrott le
position (Step 2), unsnap the bushing clip,
separate the linkage from the bushing, and
remove the bushing from the lever. Follow Steps
3 and 4 in Checking the Initial Adjustment.
5. Reconnect the dampening spring into its
governor lever hole from the bott om. Reinstall
the bushing and reatt ach the thrott le linkage. See
Figure 5-24. Reatt ach the governor spring in the
marked hole.
6. Start the engine and allow it to fully warm up
and establish closed loop operation
(approximately 5-10 min.). Check the speed
sett ings and adjust as necessary, fi rst the low idle
speed, and then the high-speed sett ing.
NOTE: Thrott le body and air cleaner assembly
must be securely fastened with three hex
fl ange nuts to the intake manifold prior to
att empting to set the governor.
