Every 4500 Hours Maintenance - Komatsu D37EX-24 Operation & Maintenance Manual

MAINTENANCE PROCEDURE MAINTENANCE
METHOD FOR CHECKING FOR MISSING FUEL SPRAY PREVENTION CAP,
HARDENING OF RUBBER
The fuel spray prevention caps (12 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 the fuel spray prevention caps visually or with a finger to see if any of them has slipped off, or the rubber
portion is hardened.
If there is any loose bolt or hardened rubber, ask your Komatsu distributor for replacement.
