Understand the critical function of the engine and machinery parts we supply, including components for Cummins, Komatsu, Caterpillar, Isuzu, Kubota, Yanmar, and Weichai.
Liner Kit (Cylinder Liner): Component installed in the Engine Block to protect the cylinder wall. Example: KOMATSU PC300-7 SAA6D107E-1 Liner Kit.
Piston: Found in the Engine Cylinder, it transfers force from gas to the crankshaft. Example: CATERPILLAR 320D C6.4 Piston.
Crankshaft: Located in the Engine Block, it converts reciprocating motion into rotary motion. Example: CUMMINS QSB6.7 Crankshaft.
Valve Guide: Installed in the Cylinder Head, it guides the movement of the valve stem. Example: ISUZU 6HK1 Valve Guide.
Flameout Solenoid: Part of the Fuel System, it stops fuel supply to shut down the engine. Example: YANMAR ViO80 4TNV98 Flameout Solenoid.
Radiator: Component of the Cooling System, dissipates heat from engine coolant. Example: KUBOTA KX080-3 V3307 Radiator.
Pressure Switch: Found in the Control System, it monitors pressure and triggers alarms/controls. Example: WEICHAI WP10 Pressure Switch.
Nozzle (Fuel Injector Nozzle): Located in the Fuel System/Injector, it sprays fuel into the combustion chamber. Example: CATERPILLAR 330D C9 Nozzle.
Engine Bearing (Main/Con Rod): Installed in the Engine Block/Connecting Rod, it reduces friction between moving parts. Example: KOMATSU PC450-8 SAA6D125E-5 Engine Bearing.
Accelerator Motor: Controls the throttle/speed in the Throttle System. Example: ISUZU 4BG1 Accelerator Motor.
Engine overheating in a Komatsu PC200-8 Excavator (SAA6D107E-1 engine) often stems from cooling system issues. Potential causes include a faulty water pump, low coolant level (which the 7861-92-4800 Float Switch is designed to detect), or a clogged radiator.
Troubleshooting & Solution:
Check the coolant level and ensure the Float Switch sensor is functioning correctly.
Inspect the radiator for blockages and perform a coolant flush if necessary.
Check the tension and condition of the Fan Cooling Belt for slippage.
If the engine still overheats, inspect and replace the water pump or thermostat.
A proactive maintenance plan involves daily fluid checks, regular replacement of Gasket Kits and filters, and scheduled inspection of major components like the Crankshaft and Engine Bearing. Always use high-quality OEM Quality Engine Spares to ensure machine longevity and safety.
