mounting clamps (2 places) for the high-pressure piping between the supply pump and the common rail. If there
are any problems, the parts must be replaced. In this case, ask your Komatsu distributor for replacement.

CHECK FOR MISSING FUEL SPRAY PREVENTION CAP, HARDENING OF RUBBER:PC-AEFU-288K00A
The fuel spray prevention caps (14 places) on the fuel injection piping and both ends of the high-pressure piping
act to prevent the fuel from coming into contact with high-temperature parts of the engine and causing a fire if the
fuel should leak or spray out. Check visually and touch by hand to check that there are no missing caps, loose
bolts or hardening of the rubber. If there are any problems, the parts must be replaced. In this case, ask your
Komatsu distributor for replacement.
