Fuel Filter/Water Separator Replacement
Replace the fuel filter/water separator at intervals according to the Maintenance Inspection
Schedule.
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 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.

e:: To achieve proper refrigeration system capacity in High Speed engine operation, it is
important to ensure the engine high speed throttle is set properly.
1. Shut the unit off.
2. Remove the ball socket from the throttle bracket ball.
3. Energize the high speed solenoid by using the Interface Board Test Mode to energize the high
speed solenoid while the engine is not running.
4. Adjust the ball socket on the end of the linkage rod as necessary to make it align with the
throttle bracket ball with the throttle bracket held tight against the high speed stop screw.
5. If alignment is not possible or there is a slight gap between the high speed stop screw and
throttle bracket, de-energize the solenoid and shorten the linkage by threading the ball socket
in up to one turn. Reassemble and energize the solenoid. Verify that the throttle bracket is
tight against the high speed stop screw.
