ENGINE MAINTENANCE
AIR CLEANER SERVICE:
Clean out the dust cup every 50 hours. Loosen the clamps around the cup and housing
and remove the cup. Dump dust out of cup. Clean gasket and sealing surfaces with a
damp cloth. Replace cup gasket if it shows signs of damage. Replace cup with arrows
pointing up and tighten clamp.
Clean the intake cap screen every 50 hours, and perform a thorough inspection of the air
intake pipes and joints.
Clean the filter element every 250 hours or every 3 months, whichever comes sooner
and replace the element every 500 hours or 6 months. Remove and clean the dust cup
and gasket, and the intake cap. Remove the wing nut on the element and gently remove
the element. Bumping the element during removal may cause dirt to fall into the clean
air tube. Clean the inside of the housing carefully with a damp cloth. To clean the
element, use a compressed air blower nozzle with less than 100 psi (7 bar) and blow air
from the inside of the element. Shake dust off of the outside of the element. Make sure
the gaskets and element fit properly and reassemble, being careful not to allow any dust
into the intake pipe.
Do not remove an element just for inspection. This may do more harm than good. You
cannot judge the element condition by its appearance. If you think the filter may need
service, remove it and replace or clean it before reassembling air cleaner.
Conditions where more dirt than usual is in the air, especially soot, will make more
frequent service necessary. If there is a significant amount of dust in the dust cup when
it is cleaned every 50 hours, clean the element every 100 hours and replace it every
200 hours--or more frequently in extremely dusty conditions. Excessive exhaust smoke
or loss of power may indicate a plugged filter.
COOLING SYSTEM:
Check the level of coolant in the radiator overflow tank daily. Add a mixture of antifreeze
and distilled water to the overflow tank as required to maintain the coolant level. Check
the radiator fins for dirt or debris daily and wash the fins with a pressure or steam
cleaner every 50 hours or as required. Check the antifreeze protection level every 500
hours. Every two years, flush the cooling system and replace the thermostat and
coolant. Pressure test the system as specified by the engine manufacturer.
SPARE PARTS LIST:
A spare parts list (including oil filter, fuel filter, etc.) may be found in the Parts Manual
under Engine Installation. Replace engine parts only with genuine OEM parts as
required by EPA regulations.
MAJOR ENGINE SERVICING OR OVERHAUL:
Major servicing or overhaul is beyond the scope of this manual. Consult authorized
engine service manual or rely on an authorized engine service center.
