Caterpillar 3116 Piston: A reciprocating component in the cylinder, converting gas pressure into mechanical force.
Komatsu 6D102 Valve Guide: A sleeve fitted into the cylinder head to guide the movement of the engine valve stem.
Isuzu 4BG1 Crankshaft: Located in the engine block, converting the piston's reciprocating motion into rotational motion.
Yanmar 4TNV94L Nozzle: Part of the fuel injection system, spraying atomized fuel into the combustion chamber (Found in Yanmar mini-excavators).
Cummins QSB6.7 Engine Bearing: Supports rotating shafts like the crankshaft and connecting rods (In Cummins QSB6.7 engines in various excavators).
Weichai WP10 Gasket Head: A seal between the engine block and cylinder head, sealing the combustion chamber (Weichai engines in heavy trucks/equipment).
Kobelco J05E Pressure Switch: An electrical switch that responds to pressure changes, often monitoring engine oil pressure in Kobelco excavators.
Caterpillar C7 Flameout Solenoid: An electro-mechanical device that controls the fuel supply to stop the engine (Caterpillar equipment like the 320D).
Komatsu 6D114 Radiator: Located at the front of the machine, responsible for cooling the engine's coolant to maintain operating temperature (Komatsu PC300-8 excavator).
Isuzu 6HK1 Cylinder Block: The foundation of the engine, containing the cylinders, cooling passages, and oil passages (Isuzu engine powering Hitachi excavators).
Komatsu PC400-8 Excavator: Engine Overheating Troubleshooting
Fault: The water temperature gauge rapidly rises to the red zone, and the engine loses power.
Solution: A common cause is a failed Fan Cooling Belt or a clogged Radiator. Check the Belt tension and condition; replace if frayed or loose. Flush the Radiator and cooling system to remove debris and scale buildup. Also, inspect the Float Switch (Part No. 7861-92-4800) to ensure the coolant level sensor is functioning correctly, preventing low-coolant conditions.
General Maintenance Tip: Regularly change the Engine Bearing and Crankshaft oil and filters every 250 hours to ensure optimal lubrication and prevent premature wear of high-speed components like the Turbocharger 320-06159.
