FUEL SYSTEM
With the engine at normal operating temperature, adjust
engine speed as follows:
Idle Speed (See FIGURE 21.)
Loosen the locknut and turn the idle speed screw until
the idle speed is within the specifications shown in the
MAINTENANCE SCHEDULE. Tighten the locknut.

Governor Speed (Diesel) (See FIGURE 22.)
1. Adjust the idle speed to 725 to 775 rpm.
2. Disconnect the throttle cable (6) at the throttle lever
(9) on the fuel injection pump. Push the throttle or
Monotrol pedal (1) until it stops against the floor plate
(2). Hold the pedal in this position with a rod.
3. Connect the end of the throttle cable (6) to the rod end
(8) on the throttle lever (9). Make sure the end of the ca-
ble is connected securely with the rod end, but the cable
is not tight. Tighten the jam nut (7) to hold the cable to
the rod end.
4. Adjust the cable housing at the bracket on the engine
(4) to obtain full throttle at the engine. Tighten the jam
nuts (5) on the cable housing.
5. Remove the rod from holding the pedal in the open
position. If necessary, adjust the pedal stop (3) so that
there is approximately 3 mm (0.13 in) free pedal when
the engine is at idle speed.
6. On units with a Monotrol pedal, move the pedal from
Forward to Reverse and Reverse to Forward several
times. The pedal must shift to the opposite direction be-
fore the throttle opens.
