Turbocharger: Mounted on the exhaust manifold to increase engine power. Example: Caterpillar 320D C6.4 Turbocharger.
Fuel Injector: Located in the cylinder head to spray fuel into the combustion chamber. Example: Komatsu PC300-8 6D114 Fuel Injector.
Water Pump: Installed on the engine block front to circulate coolant. Example: Isuzu 4HK1 Engine Water Pump.
Crankshaft: Positioned at the bottom of the engine block, converting linear motion to rotation. Example: Cummins 6BT5.9 Crankshaft.
Piston Ring: Fitted around the piston to seal combustion gas. Example: Yanmar 4TNV94 Piston Ring Set.
Cylinder Head Gasket: Placed between the cylinder head and block to prevent leaks. Example: Kubota V2403 Head Gasket.
Oil Pump: Located inside the oil pan or front cover to provide lubrication. Example: Weichai WP10 Oil Pump.
Main Bearing: Supports the crankshaft within the engine block. Example: Caterpillar E330C C9 Main Bearing.
Fan Pulley: Attached to the front of the engine to drive the cooling fan. Example: Komatsu PC200-6 6D102 Fan Pulley.
Solenoid Valve: Controls fuel shut-off or hydraulic flow. Example: Isuzu 6HK1 Flameout Solenoid.
Case Study: Engine Overheating in Komatsu PC200-7 (6D102 Engine)
Problem: The operator reported rising engine temperatures during heavy-duty excavation tasks.
Diagnosis: Upon inspection, the Belt Pulley Bracket (6732-61-3120) was found to have a hairline crack, leading to loose belt tension. This caused the water pump to slip, resulting in poor coolant circulation.
Solution: Replace the damaged bracket with our high-precision 6732-61-3120 part. Inspect the belt for wear and ensure proper tensioning. Regularly check pulley alignment every 500 hours to prevent future failures.
