PERIODIC INSPECTION AND MAINTENANCE PROCEDURES
6-11
Inlet Exhaust System
Inspection of Turbocharger
Make sure the engine is cool before inspecting the
turbocharger. Also check that the compressor
wheel is not rotating before inspection.
Disconnect the pipe from the air inlet side.
Hold the compressor wheel nut by hand and turn
the wheel to feel for looseness and listen for abnor-
mal noise. Replace the bearings if the wheel is
noisy or loose.
Note: For replacement of the bearing, consult a Mit-
subishi dealer.
If the color of exhaust gas is abnormal, also achieve inspection for the turbocharger.
Draining Water From Exhaust
Muffler
Do not touch the exhaust muffler immediately after
the engine stops operation because it remains
extremely hot for a while. Conduct work after the
exhaust muffler cools.
Remove the drain plug and allow water to drain
from the exhaust muffler.
Cleaning Pre-Cleaner
Do not service the air cleaner while the engine is
running. Maintenance of the air cleaner while the
engine is in operation can cause dust to enter the
engine and result in rapid wear of parts, leading to a
shorter service life.
Remove dust from the inlet side of the pre-cleaner
installed to the silencer of the turbocharger. Be sure
to keep the pre-cleaner clean to ensure optimum
engine performance.
1 Remove the pre-cleaner from the silencer, and
hand-wash the pre-cleaner with a mild detergent.
2 Rinse the pre-cleaner with clean water.
3 After drying thoroughly, reinstall the pre-cleaner to the silencer.
Note: If the pre-cleaner is cracked or damaged, replace.
