Governor Inspection
A governor failure can cause engine starting failure, loss
of engine speed control, or engine surging (hunting).
Before removal and disassembly of the engine the
following inspections are recommended:
1. Stop the engine, l
ower the implement and engage the
parking brake. Open the engine hood.
2. Remove the governor tie rod cover (Fig. 28).
3. While holding the stop lever (Fig. 33) in the stop
position (towards the rear of the machine) turn the
ignition key switch quickly to the START position and
release it to the ON positon. This will retract the stop
solenoid plunger, allowing movement of the injection
pump control rack.
4. Push the tie rod forward only with only enough f
orce
to overcome the spring pressure and operate the speed
control lever (or throttle lever). You should feel the
governor lever, under spring tension, move the tie rod
and control rack as the lever is operated.
5. If the control rack does not move move correctly,
d
isconnect the tie rod from the injection pump control
rack. Make sure the injection pump control rack moves
freely. If it does not, check for injection pump problems.
6. Failure of the speed control lever or governor lever to
move when the tie rod is disconnected may indicated a
problem with internal parts of the governor.
