Stop Solenoid Replacement (Fig. 34)
The Mitsubishi engine uses an electrical solenoid to
shut off the fuel supply and stop the engine. An emer•
gency stop lever is provided in case the stop solenoid
fails. If a solenoid failure is suspected, it can be checked
by attaching 12 VDC battery leads to the solenoid
terminals. If the solenoid operates when battery contact
is make the stopping failure is elsewhere in the electrical
system (refer to Chapter 6).
1.
Turn the engine off (with emergency stop lever if
necessary), and remove the key from the ignition switch.
2.
Disconnect the solenoid wires from the main wire
harness.
Figure 34
3. Loosen the nut securing the solenoid to the engine
and unscrew the solenoid. (Use a 36 mm wrench.)
4. Remove the gasket and the nut and install them on
the new solenoid. Thread the nut fully onto the solenoid.
Remove the cap from the old solenoid.
5. Start to thread the solenoid into the cylinder block.
6. Push the plunger on the solenoid fully in and hold it
in this position.
7. Rotate the emergency engine stop lever to the STOP
position (counterclockwise).
8. Continue to hold the solenoid plunger in and thread
the solenoid into the cylinder block until the inner end of
the plunger contacts the control rack of injector pump.
Contact will be indicated when the outside end of the
plunger is pushed away from the solenoid body.
9. When contact is indicated, discontinue threading the
solenoid into the cylinder block. Turn the solenoid slowly
outward until the plunger again contacts the solenoid
body, then rotate the solenoid body one eighth turn
further out.
10. Hold the solenoid body to prevent it from turning and
tighten the nut against the cylinder block to secure the
adjustment. DO NOT over tighten the nut or the solenoid
may become distorted causing it to malfunction.
11. Connect the solenoid wires, install the cover.
