1. Crankshaft (CUMMINS QSM11): The main rotating component of the engine that converts linear piston motion into rotation. Installed in the lower engine block.
2. Turbocharger (KOMATSU PC200-8 / 6D107): Increases engine efficiency by forcing extra air into the combustion chamber. Mounted on the exhaust manifold.
3. Water Pump (CATERPILLAR 320D / C6.4): Circulates coolant throughout the engine to maintain temperature. Located at the front of the engine block.
4. Piston (ISUZU 4HK1 / ZX200-3): Moving component contained by a cylinder made gas-tight by piston rings. Located inside the cylinder liner.
5. Fuel Injector (KUBOTA V2403): Delivers atomized fuel into the combustion chamber. Installed in the cylinder head.
6. Oil Pump (YANMAR 4TNV98): Circulates engine oil under pressure to rotating bearings. Located inside the oil pan or front cover.
7. Radiator (WEICHAI WD10): A heat exchanger used to cool the engine's internal combustion. Located at the front of the vehicle/machine.
8. Main Bearing (CUMMINS 6BT5.9): Bearings on which the crankshaft rotates. Located in the crankcase.
9. Gasket Head (KOMATSU 6D125): Seals the cylinders to ensure maximum compression and prevent leakage. Located between the block and head.
10. Float Switch (KOMATSU 7861-92-4800): Monitors fluid levels in tanks. Commonly used in excavator hydraulic or fuel tanks.
Common Issue: Engine Overheating (Device: KOMATSU PC300-7 Engine: 6D114)
Symptoms: Temperature gauge entering red zone, loss of power, steam from radiator.
Solution: Check the Water Pump (Part No. 6151-62-1101) for bearing failure or impeller erosion. Inspect the thermostat and radiator for blockages. Replace with high-quality Honour Time replacement parts to ensure thermal stability.
Maintenance Tip: Always use high-quality coolant and change your Oil Filter and Fuel Filter every 500 hours to extend the life of your Piston Rings and Cylinder Liners.
