Check For Loose Rops Mount Bolts - Komatsu D475A-5E0 Operation & Maintenance Manual

MAINTENANCE MAINTENANCE
With the poor fuel arrangement specification machine, two fuel
filters are additionally installed to the engine block on the other
side.
(This gives a total of two each on the left and right.)
NOTICE
Do not fill the fuel filter cartridge with fuel.
Remove cap (A) and install the fuel filter.
4. Clean the filter head, coat the packing surface of the new filter
cartridge thinly with oil, then install the filter cartridge to the filter
head.
5. When installing, tighten until the packing surface contacts the
seal surface of the filter holder, then tighten a further 3/4 of a
turn.
If the filter cartridge is tightened too far, the packing will be
damaged and this will lead to leakage of fuel. If the filter
cartridge is too loose, fuel will also leak from the packing, so
always tighten to the correct amount.
6. After filter cartridge (2) has been replaced with a new one, bleed air from the cartridge in reference to "BLEED
AIR FROM FUEL CIRCUIT (PAGE 4-52)".
For details of the poor fuel arrangement specification machines (if equipped), see "BLEEDING AIR FROM FUEL
CIRCUIT WITH THE ELECTRIC PRIMING PUMP (PAGE 4-53)".

If any damaged bolt is found, replace the bolt with a genuine Komatsu bolt.
