Replacing and/or Adjusting Engine Stop Solenoid
See Chapter 5 - Electrical System for information about
testing the engine stop solenoid.
An improperly adjusted stop solenoid can result in fail-
ure of the engine to stop when the key switch is turned
off or could cause injection pump damage or malfunc-
tion.
Removing the Stop Solenoid
1. Stop the engi
ne. If the engine will not stop when the
ignition key switch is turned off, manually push the stop
lever (Fig. 14) toward the rear of the machine until the
engine stops.
2. Disconnect the solenoid electrical connector.
3. Loosen the nut securing the solenoid to the engine
and unscrew the solenoid.
4. If you will be installing a new solenoid, remove the
gasket and nut from the old solenoid and install them on
the new solenoid. Thread the nut completely on the new
solenoid.
Installing and/or Adjusting the Stop Solenoid
1. Remove the governor tie rod cover (Fig. 28).
2. Apply thread sealant to the solenoid threads.
3. Thread the solenoid into the engine.
4. Thread the solenoid into t
he engine while moving the
tie rod back and forth (Fig. 29). Stop screwing the
solenoid into the engine when there is no free play in
the tie rod.
5. Turn the solenoid outward (counterclockwise) 1/4 to
1
/2 turn. There should be a small amount of free play in
the injector pump control rack 0.01 - 0.03 in. (0.3 -
0.7 mm).
IMPORTANT: No free play in the control
rack with
the solenoid de-energized (plunger out) may cause
injection pump damage or malfuntion. Excess free
play 0.04 in. (1 mm) or more will prevent the engine
from stopping when the solenoid is de-energized.
6. Remove the cover cap screw from the engine to get
a
ccess to the solenoid nut (Fig. 28).
7. Hold the solenoid b
ody to prevent it from turning and
tighten the nut against the engine to secure the adjust-
ment. Do not over tighten the nut. If the nut is over
tightened, the solenoid may become distorted and will
not operate correctly.
8. Install the cover
cap screw that was removed from
the engine in step 6.
9. Connect the solenoid electrical connector.
10. Install the governor tie rod cover.
