MAINTENANCE
2.
Loosen the nuts (2) and pull up the nets (3).
3.
Clean the nets (3) that you pulled up.
(They will be installed again in the step 8.)
4.
Remove the bolts (4) (10 places), four-claw clamps (11) (2
places), clamp (12) (1 place), and move the bracket (5) to
make a clearance between the radiator fin (6) and oil cool-
er fin (7).
5.
Check the front and rear sides of radiator fins (6), oil cooler
fins (7), aftercooler fins (8), condenser fins (9), and radia-
tor fins (10) of hybrid devices. If there is any mud, dirt,
leaves, etc. stuck to the fins, blow it off with the com-
pressed air.
NOTICE
Steam or water may be used instead of the com-
pressed air. However, when performing powerful
steam cleaning (high-pressure machine wash) of the
heat exchange equipment (radiator, oil cooler, after-
cooler, fuel cooler, air conditioner condenser), main-
tain a sufficient distance from the machine when per-
forming the work. If steam cleaning (high-pressure ma-
chine wash) is performed at close distance, there is a
danger that the internal fins of the heat exchange
equipment may be deformed, and this will cause early
clogging and breakage of the equipment.
6.
Visually check the rubber hose connected to the heat ex-
change equipment. Check the hose clamp for looseness
as well.
If the rubber hose is cracked or become fragile, ask your
Komatsu distributor for the replacement.
If the hose clamp is loose, tighten it.
7.
Remove the undercover (13) and blow out the mud, dirt,
and leaves to the outside.
8.
Push in the cleaned nets (3) back to the original place and
install it with nuts (2).
9.
Install the bracket (5) with bolts (4).
10. Install the four-claw clamps (11) and clamps (12) to the
original positions.
11. Before installing the undercover (13), check that the net (3)
is securely installed in guide (14).
If the net (3) is coming off the guide (14), the net (3) may
interfere with the core and damage it.
12. Install the undercover (13).
