CDC EXHAUST PILOT VALVE
System filter cleaning problems are isolated by pushing the stepper reset button. If operation begins and then
ceases, repeat the sequence and note the exhaust valve that fails to open. The part of the system operating
this exhaust valve is most likely the problem. Check related pilot tubing leakage, exhaust valve seal leakage,
and pilot valve sticking.
ENGINE AIR INTAKE SYSTEM
NOTE
Monitor the air filter indicator daily
The importance of maintaining an air filter cannot be overemphasized. Dirt ingested through improperly
installed, improperly serviced, or inadequate air filter elements wears out more engines than long hours of
operation. Even a small amount of dirt will wear out a set of piston rings in just a few hours. Operating with a
clogged air filter element also causes the fuel mixture to be richer, which can lead to formation of harmful
sludge deposits in the engine. Always cover the air intake when the air filter is removed for servicing. Do not
neglect servicing the air filter. Use only approved replacement parts. Keep all other air intake components
such as hoses and clamps secure and in good condition to prevent entrance of unfiltered air.
Over maintenance can cause more damage than good. Removing the air filter element more often than is
needed allows contaminants to enter the engine unnecessarily.
AIR FILTER
The engine air filter housing includes a dust cap and a dry cartridge type air filter element. The dust cap
must be emptied of dirt daily. The air filter element must be replaced every 75 to 100 hours. The filter
element must be replaced if it is damaged or has been cleaned three times.
Replace the engine air filter only when the Yellow Filter
Service Indicator reaches the red band at the top of the
indicator. The yellow indicator will stay at the red band
when the engine is off. Reset the indicator by depress-
ing the black button at the bottom of the indicator.
TO REPLACE AIR FILTER ELEMENT
1.
Stop the engine and engage the machine parking brake.
WARNING
Always park on a level surface, stop the engine, and engage parking brake before working on the machine to
keep it from creeping or rolling.
2.
Tilt the hopper forward until it is over the bumper.
3.
Unscrew the clamp ring on the filter.
4.
Remove the dust cap.
5.
Empty the dust cap.
6.
Remove the filter wing nut.
7.
Gently pull the filter element out of the filter housing.
