Fuel Injector (Isuzu 4HK1 - ZX200-3): Delivers atomized fuel to the combustion chamber.
Crankshaft (Cummins 6BT - PC200-6): Converts linear piston motion into rotation; located in the cylinder block base.
Water Pump (Komatsu 6D102 - PC200-7): Circulates coolant; mounted on the front of the engine block.
Piston Ring (Yanmar 4TNV94 - VIO55): Seals the combustion chamber; fitted onto the piston grooves.
Main Bearing (Weichai WD615 - Loader): Supports the crankshaft; installed in the crankcase.
Oil Pump (Kubota V2403 - KX161): Forces oil through the lubrication system; driven by the crankshaft.
Gasket Head (Mitsubishi 6D16 - HD820): Seals the block and head; placed between the cylinder head and block.
Solenoid (Hino J08E - SK350-8): Controls fuel shut-off; attached to the fuel injection pump.

Maintenance Solution & Case Study

Device Model: Komatsu PC200-8 Excavator
Issue: "L01" Error code or unstable engine RPM. Engine fails to reach maximum speed under load.
Solution: Inspection revealed a faulty 7861-92-4800 float switch and Throttle Motor wear. Replacing both with our high-precision parts restored engine response time and eliminated dashboard errors.
Maintenance Tip: Always check wiring harnesses for moisture when replacing electrical sensors in excavators like the PC200-8 or CAT 320D.
