1. Cummins QSB6.7 Fuel Injector: Located in the cylinder head, delivers pressurized fuel. Example: Cummins QSB6.7 on Hyundai R210-9.
2. Komatsu PC200-8 Turbocharger: Mounted on the exhaust manifold to increase engine air intake. Example: Komatsu SAA6D107E engine.
3. Caterpillar 320D Water Pump: Installed on the front of the engine block to circulate coolant. Example: CAT C6.4 engine.
4. Isuzu 6HK1 Crankshaft: Located at the bottom of the engine block, converts linear motion to rotation. Example: Hitachi ZX330-3.
5. Kubota V2403 Piston: Moves within the cylinder liner to compress fuel/air. Example: Bobcat S185 Skid Steer.
6. Yanmar 4TNV98 Gasket Head: Sealing layer between cylinder head and block. Example: Yanmar 4TNV98 Excavator.
7. Weichai WD615 Oil Pump: Located inside the oil pan to provide lubrication. Example: SDLG Wheel Loader.
8. Caterpillar C9 Alternator: Belt-driven component providing electrical power. Example: CAT 330D Excavator.
9. Komatsu PC300-7 Radiator: Cooling unit located at the rear of the machine. Example: Komatsu 6D114 engine.
10. Cummins QSM11 Camshaft: Controls the timing of valve opening/closing. Example: Terex Dump Truck.
Common Fault: Overheating in Caterpillar 320D Excavator
Solution: Check the water pump and radiator for blockages. In many cases, replacing the CAT C6.4 Fan Belt and cleaning the cooling fins resolves the temperature spikes. Regular maintenance of the engine bearing and lubrication system is essential to prevent internal friction damage.
