Understanding the components of your machinery helps in better maintenance. Here are common parts we supply:
Cummins QSB6.7 Piston Ring: Sealed metal rings installed on the Piston inside the Cylinder Block to maintain compression.
Komatsu PC200-8 Turbocharger: Forced induction device installed on the Exhaust Manifold to increase engine power.
Caterpillar C9 Fuel Injector: Precision valve installed in the Cylinder Head to spray diesel into the combustion chamber.
Isuzu 6HK1 Water Pump: Coolant circulation pump installed on the Front Gear Case to regulate engine temperature.
Yanmar 4TNV98 Crankshaft: Main rotating shaft installed in the bottom of the Engine Block converting piston motion to rotation.
Kubota V2203 Cylinder Head Gasket: Sealing material installed between the Block and Head to prevent leaks.
Weichai WP10 Oil Cooler: Heat exchanger installed near the Oil Filter to cool engine lubricant.
Kobelco SK200-8 Throttle Motor: Stepper motor installed near the Injection Pump to control engine RPM.
Volvo D6D Liner Kit: Includes cylinder sleeve, piston, and rings installed in the Engine Block for a complete overhaul.
Hitachi ZX330 Main Bearing: Friction-reducing metal shell installed on the Crankshaft Journals to support rotation.
Scenario: A Komatsu PC200-8 displays a high engine temperature warning, but the radiator seems full.
Fault Analysis: The issue might not be the coolant level itself, but the Float Switch (Sensor). If the sensor is corroded or stuck, it may send false signals to the ECU, or fail to trigger the fan properly if the system relies on it for logic validation.
Solution: Check the resistance of the 7861-92-4800 sensor. If the reading is open or shorted out of spec, replace it immediately with our high-quality aftermarket unit to restore proper monitoring and protect your engine.
