4.
Lubricate the canister seal with clean fuel.
5.
Screw the new canister on hand-tight. Using a strap
wrench, tighten another 1/4 turn.
Engine Speed Adjustments
When the diesel engine fails to maintain the correct engine
speed, check the following before adjusting the speed:
1.
Check the fuel inlet screen. Check the speed.
2.
Bleed the air out of the fuel system. Check the speed.
3.
Bleed the air out of the nozzles. Check the speed.
Make the engine speed adjustments with the engine fully
warmed up.

High Speed
1.
Use the Service Test Mode to run the unit in high speed
and check the high speed rpm. It should be 2175 to
2225 rpm.
2.
Shut the unit off.
3.
Remove the ball joint from the eye bolt in the high
speed solenoid.
4.
Remove the boot from the high speed solenoid.
5.
Pull the plunger out of the solenoid enough to loosen
the jam nut. An Allen wrench placed in the hex opening
in the face of the plunger will keep the plunger from
turning. Turn the plunger eye bolt clockwise to increase
the speed and counterclockwise to decrease the speed.
6.
Replace the ball joint, start the unit and check the
speed. When the speed is correct, tighten the jam nut
and replace the solenoid boot.
NOTE: If the correct speed cannot be set close
enough with half turns of the eye bolt, use the Allen
wrench to turn the plunger in smaller increments.
Low Speed
1.
Loosen the jam nut on the low speed adjustment screw.
2.
Use the Service Test Mode to run the unit in low speed.
Adjust the screw to obtain the correct speed. It should
be 1425 to 1475 rpm.
3.
Tighten the jam nut and recheck the speed.
Injection Pump Timing
This timing procedure requires fuel pressure at the injection
pump inlet. This can be accomplished by pumping the prim-
ing pump by hand, or by using an electric fuel pump to sup-
ply fuel to the fuel pump inlet.
1.
Place the On-Off switch in the OFF position.
