Cummins QSB6.7 Turbocharger: Located on the exhaust manifold to increase engine power in excavators.
Komatsu PC200-8 Main Valve: The central control unit of the hydraulic system mounted on the chassis.
Caterpillar C7 Fuel Injector: Delivers high-pressure fuel directly into the combustion chamber.
Isuzu 6HK1 Water Pump: Circulates coolant throughout the engine block to prevent overheating.
Yanmar 4TNV98 Piston Ring: Seals the combustion chamber and regulates oil consumption.
Kubota V2403 Starter Motor: High-torque motor used to crank the engine during startup.
Weichai WP10 Oil Pump: Ensures lubrication for the crankshaft and camshaft bearings.
Komatsu D65 Dozer Pressure Switch: Monitors hydraulic pressure and sends signals to the monitor.
Caterpillar 320C Fan Cooling: Pulls air through the radiator to dissipate heat.
Isuzu 4JB1 Crankshaft: Converts linear piston movement into rotational force.
Device: Komatsu PC210-8 Excavator
Problem: The hydraulic system became extremely sluggish, and the engine temperature warning light flickered inconsistently.
Solution: Upon inspection, the Pilot Pump (702-16-01230) was found to have internal wear, leading to low pilot pressure. Simultaneously, the Float Switch (7861-92-4800) was malfunctioning due to sensor corrosion. By replacing both with Honour Time high-quality parts, the machine regained full hydraulic speed and accurate cooling system monitoring.
Maintenance Tip: Always check hydraulic oil filters every 500 hours and clean the coolant level sensor terminals to prevent false alerts and part failure.
