ENGINE MAINTENANCE
Refer to the engine manual for engine maintenance.
AIR CLEANER SERVICE
Tier 3 Engine:
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. Perform a thorough inspection of the air
intake pipes and joints every 250 hours.
Replace the filter element every 500 hours or every year, whichever comes sooner.
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. Make sure the gaskets and element fit properly and reassemble.
Never remove an element for inspection. This will do more harm than good. You cannot
judge the element condition by its appearance. Also do not try to clean a used element. It
is safer to keep the used element in place until a replacement can be obtained.
Conditions where more dirt than usual is in the air, especially soot, will make more frequent
changes necessary. Excessive exhaust smoke or loss of power may indicate a plugged
filter.
Tier 4i Engine:
Check the air filter restriction indicator daily with the engine running. If necessary, use a
ladder or steps to view the restriction indicator. If the indicator is in the “Replace” zone,
replace the primary and secondary filter. If the filter has not been changed for over 1000
hours, replace the filter regardless of the restriction indicator reading.
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 and Transmission Installation.
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.
