Piston (8-97108-622-2): Reciprocates in the cylinder, converting thermal energy into mechanical work. Isuzu NPR Truck 4JB1 Piston.
Piston Ring Set (8-94247-867-1): Seals the combustion chamber and manages oil. Kubota KX080-3 V3800 Piston Ring.
Cylinder Liner: Forms the sliding surface for the piston. Located within the cylinder block. Cummins QSK60 Cylinder Liner.
Crankshaft Bearing (Main Bearing): Supports the crankshaft within the cylinder block. Komatsu PC400-7 SAA6D125E Main Bearing.
Connecting Rod Bearing (Con Rod Bearing): Connects the connecting rod to the crankshaft journal. Caterpillar D8R 3406 Connecting Rod Bearing.
Turbocharger: Increases engine power by forcing extra air into the combustion chamber. Mounted on the exhaust manifold. Weichai WD615 Turbocharger.
Water Pump: Circulates coolant through the engine and radiator. Mounted on the front of the engine block. Yanmar ViO70-3 4TNV98 Water Pump.
Fuel Injector: Sprays fuel into the engine cylinders. Installed in the cylinder head. Cummins QSB4.5 Fuel Injector.
Oil Pump: Circulates lubricating oil throughout the engine. Located inside the oil pan or front cover. Caterpillar 320D C6.4 Oil Pump.
Thrust Washer: Controls the axial (end) play of the crankshaft. Located at a main bearing journal. Komatsu WA380-6 SAA6D107E Thrust Washer.
Equipment: Komatsu PC200-8 Excavator (Engine: SAA6D107E-1)
Fault: The engine temperature gauge consistently reads high during operation, leading to a power derate.
Solution: Start by checking the coolant level and the function of the Water Pump. A common cause is a failing water pump impeller or a blocked radiator. If those are clear, inspect the Cylinder Head Gasket (part of the Overhaul Gasket Kit). A blown head gasket can allow combustion gases to leak into the cooling system, causing pressure build-up and localized overheating. Replace the affected component immediately to prevent catastrophic engine failure involving parts like the Piston and Cylinder Liner.
