Understanding where these critical engine components are installed is key to successful engine maintenance and repair:
Caterpillar 320D S6K Piston: The main moving component installed within the engine cylinder block, transmitting force.
Komatsu PC400-7 6D125 Gasket Head: Installed between the cylinder block and the cylinder head to seal the combustion chamber.
Cummins QSB6.7 Connecting Rod Bearing: Installed inside the connecting rod to allow smooth rotation on the crankshaft journal.
Isuzu EX350 6WG1 Turbocharger: Installed on the exhaust manifold to compress air entering the engine cylinders.
Yanmar ViO55-6 4TNV88 Water Pump: Installed on the engine block, circulating coolant through the engine and radiator.
Weichai WD615 Cylinder Liner: A replaceable sleeve installed inside the engine block where the piston travels.
Caterpillar D6T C9 Fuel Injector: Installed in the cylinder head to spray atomized fuel into the combustion chamber.
Kubota U35-3 V2203 Oil Pump: Installed inside the engine block or oil pan to circulate engine oil for lubrication.
Komatsu WA380-6 6D107 Flameout Solenoid: Installed on the fuel pump or injection system to cut off fuel supply and stop the engine.
Cummins B5.9-C Crankshaft Thrust Washer: Installed on the main bearing saddle to control the axial movement (end-play) of the crankshaft.
If your Komatsu PC300-8 excavator with a 6D114 engine experiences constant overheating, a common culprit is a failed or stuck Engine Thermostat (like the one we supply). If the thermostat is stuck closed, coolant cannot circulate to the radiator, causing rapid temperature spikes. The solution is immediate replacement of the thermostat and a full system flush.
For longevity in your Caterpillar 330D C7 engine, implement a quarterly Scheduled Oil Sampling (SOS) program. Analyzing the used engine oil detects premature wear of internal parts like C7 Engine Bearings and Cylinder Liners, identifying contaminants like dirt or coolant before major failure occurs. This proactive maintenance significantly extends the service life of your Caterpillar heavy equipment parts.
In addition to Kubota spare parts, we are a leading supplier for all major engine brands. Contact us for competitive pricing on these popular engine models and more.
