Crankshaft (CUMMINS 6CT8.3): Located in the engine block, it converts linear piston motion into rotation. Essential for heavy-duty earthmoving.
Turbocharger (KOMATSU PC300-7): Mounted on the exhaust manifold, it increases air intake for higher power output in high-altitude operations.
Main Valve (CATERPILLAR 320C): Located in the hydraulic pump assembly, it controls the flow of oil to actuators for precise boom movement.
Flameout Solenoid (ISUZU 4JG2): Installed on the fuel injection pump, it cuts off fuel supply to stop the engine immediately.
Monitor (KOBELCO SK200-6): Mounted in the operator cabin, it displays real-time engine data and system alerts.
Piston Ring (YANMAR 4TNV94): Installed in the piston grooves to seal the combustion chamber and regulate oil consumption.
Radiator (VOLVO EC210B): Located at the front of the engine bay, it dissipates heat from the coolant to prevent engine overheating.
Pressure Switch (KUBOTA KX161): Found in the hydraulic lines, it signals the controller when pressure thresholds are reached.
Fan Cooling (WEICHAI WD10): Driven by the crankshaft belt, it pulls air through the radiator for temperature control.
Water Pump (HINO J08E): Bolted to the engine front, it circulates coolant throughout the block and cylinder head.
Case Study: Excavator Throttle Response Failure (Model: KOBELCO SK210-8)
Problem: The engine stays at idle despite moving the throttle dial. The monitor displays error code P0606 or P1225.
Solution: Inspect the Accelerator Motor (YN20S00002F1). Often, the internal gears or the feedback potentiometer wear out. Replacing it with a high-precision stepping motor restores smooth RPM control. Ensure the wiring harness is not frayed before installation.
Maintenance Tip: Periodically clean the air filter and check the cooling belt tension every 500 hours to prevent premature wear of engine bearings and cylinder liners.
Precision Engineering: Designed specifically for KOBELCO SK200-8 and SK210-8 for a 100% perfect fit.
Durable Construction: Made with high-grade internal copper coils and heat-resistant casing for construction environments.
OEM Performance: Matches YN20S00002F3 specifications, providing a cost-effective alternative to original parts without sacrificing quality.
Easy Installation: Direct plug-and-play design reduces downtime in repair shops.
Wide Application: Compatible with various HINO-powered excavators used in mining and earthmoving.
