Understanding your equipment helps in better maintenance and part selection.
Turbocharger (Cummins QSB6.7): Increases engine efficiency by forcing extra air into the combustion chamber. Installed on the exhaust manifold.
Main Relief Valve (Komatsu PC200-7): Limits the maximum pressure in the hydraulic system to prevent damage. Located in the control valve block.
Fuel Injector (Caterpillar 320D): Atomizes diesel fuel into the cylinder for combustion. Installed in the cylinder head.
Water Pump (Isuzu 6HK1): Circulates coolant throughout the engine to maintain temperature. Mounted on the front of the engine block.
Oil Pump (Kubota V2403): Forces oil through the engine for lubrication. Located inside the oil pan or front cover.
Piston Rings (Yanmar 4TNV94): Seal the combustion chamber and regulate oil consumption. Installed on the piston grooves.
Gasket Head (Weichai WD615): Prevents leaks between the block and head. Located at the cylinder head interface.
Crankshaft (Komatsu 6D102): Converts linear piston motion into rotational force. The backbone of the engine block.
Flameout Solenoid (Cummins 6BT): Cuts off fuel supply to stop the engine. Installed on the fuel injection pump.
Monitor Display (Caterpillar 336D): Shows machine status and error codes. Located inside the operator's cab.
Device: Komatsu PC300-8 Excavator
Issue: Engine overheating and low coolant alarm frequently triggering despite full tank.
Solution: Diagnostic revealed the 7861-92-4800 Float Switch was stuck due to sediment. Replacing it with our high-quality replacement restored accurate sensor readings and prevented unnecessary downtime.
