Turbocharger (Cummins QSB6.7): Located on the exhaust manifold. Used to increase engine power by forcing air into the combustion chamber.
Cylinder Head (Komatsu 6D102): Installed on top of the cylinder block. It seals the cylinders and houses valves and injectors.
Piston Ring (Caterpillar S6K): Fitted in the grooves of the piston. Ensures a tight seal for combustion and regulates oil consumption.
Crankshaft (Isuzu 4HK1): Located in the bottom of the engine block. Converts linear piston movement into rotational force.
Water Pump (Kubota V2403): Mounted on the front of the engine. Circulates coolant to prevent overheating during high-load operations.
Fuel Injector (Yanmar 4TNV94): Positioned in the cylinder head. Precisely sprays fuel into the chamber at high pressure.
Main Bearing (Weichai WD615): Located within the crankcase. Supports the crankshaft and reduces friction during rotation.
Oil Pump (Caterpillar C7): Situated in the oil pan or block. Circulates engine oil to all moving parts for lubrication.
Thermostat (Komatsu 4D95): Found in the cooling line. Controls the engine operating temperature by regulating coolant flow.
Solenoid Valve (Isuzu 6BG1): Often used for fuel shut-off. Electrically controlled to stop engine operation immediately.
Device: Caterpillar 320D Excavator
Issue: Engine over-heating and low power output.
Diagnosis: Clogged radiator and worn-out Water Pump (Part No. 172-1538).
Solution: Flush the cooling system, replace the water pump with our high-quality replacement, and check the thermostat. After replacement, the engine temperature stabilized under full load.
Maintenance Tip: Always check your Float Switch (like Komatsu 7861-92-4800) regularly to ensure your cooling system fluid levels are reported accurately to the monitor. This prevents sudden engine seizure.
High precision manufacturing for Hitachi 9234284 ensures optimal fuel atomization.
Direct fit for Komatsu PC200-7/8 excavators using 7861-92-4800 float sensors.
Constructed from heavy-duty alloys for long-lasting durability in harsh mining conditions.
OEM standard performance at a competitive factory-direct price.
Strictly tested to solve starting issues and inaccurate fluid level warnings.
