Engine Maintenance
57
1. Unscrew the fuel filter/water separator
canister with a strap wrench. Drain, and
dispose of properly.
2. Clean the filter head seal surface.
3. Lubricate the canister seal with clean fuel.
4. Through one of the small openings in the top
of the canister, fill the new fuel filter/water
separator canister with clean fuel. This will
purge the air from the canister. Do not fill
canister through the center hole.
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 2200 ± 25 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 1450 ± 25 rpm.
3. Tighten the jam nut and recheck the speed.
