Maintenance Tip: Engine Overheating (Cummins QSB6.7)
A common issue in the Cummins QSB6.7 engine used in a Komatsu PC200-8 Excavator is gradual overheating. Fault: Coolant temperature rises under load and doesn't drop quickly. Solution: Beyond checking the radiator and coolant level, a sticking or slow-opening Thermostat is often the culprit. Routine replacement of the thermostat every 2,000 operating hours is a crucial preventative maintenance measure to avoid engine failure.
Liner Kit: Installed in the Cylinder Block. Example: Komatsu 6D107 Liner Kit for PC200-10 Excavator.
Piston Ring: Installed on the Piston. Example: Caterpillar C7 Piston Ring Set for D6T Dozer.
Gasket Head: Seals the Cylinder Head to the Cylinder Block. Example: Isuzu 4HK1 Gasket Head for 130-ton Excavator.
Crankshaft: Rotates in the Crankcase/Block. Example: Cummins QSB6.7 Crankshaft for Wheel Loader.
Turbocharger: Mounted on the Exhaust Manifold. Example: Yanmar 4TNV98 Turbocharger for Mini Excavator.
Water Pump: Mounted on the Engine Front. Example: Weichai WP10 Water Pump for Mining Truck.
Fuel Injector: Installed in the Cylinder Head/Manifold. Example: Cummins B5.9-C Fuel Injector for Road Roller.
Flameout Solenoid: Mounted on the Fuel Pump/Engine Block. Example: Kubota V3307 Flameout Solenoid for Skid Steer Loader.
Main Valve: Located in the Hydraulic Control Valve. Example: Komatsu PC200-8 Main Valve Spool for Excavator Hydraulics.
Valve Seat: Inserted into the Cylinder Head. Example: Caterpillar 3116 Valve Seat Insert for Generator Set.
