Engine Liner: A cylindrical part installed in the Cylinder Block. Essential for a Komatsu PC200-8 6D107 overhaul.
Piston Pin: Connects the piston to the connecting rod, located within the Piston. Used in Caterpillar 320D C6.4 Piston Pin assembly.
Thrust Plate: A washer that controls the axial movement (end play) of the Crankshaft. Found on Cummins QSB6.7 Thrust Plate kits.
Connecting Rod Bushing: A replaceable bearing inserted into the small end of the Connecting Rod. Critical for Isuzu 6BG1 Connecting Rod Bushing repair.
Flameout Solenoid: An electric device that cuts off fuel supply to stop the engine, typically mounted near the Fuel System/Pump. Key part in Yanmar ViO35 3TNV88 Flameout Solenoid operation.
Turbocharger Wastegate: A valve that regulates boost pressure by controlling exhaust gas flow to the turbine. Part of the Turbocharger on a Volvo EC210D D6E Turbocharger Wastegate.
Water Pump Impeller: The rotating component inside the Water Pump Body that circulates coolant. Used in Hino J08E Water Pump Impeller replacements.
Oil Cooler Core: A heat exchanger unit located in the Oil Cooler Housing to cool engine oil. Essential for the Mitsubishi 6D16 Oil Cooler Core.
Valve Guide: Sleeves pressed into the Cylinder Head that guide the valves. A frequent wear part in Kobelco SK350-8 J08E Valve Guide replacement.
Radiator Cap: Seals the cooling system and pressurizes it, mounted on the Radiator. Used on Kubota U35 V1505 Radiator Cap.
A common issue on the Cummins QSB6.7 engine, often found in the Komatsu PC210-10 Excavator, is sudden overheating. This can be caused by a failed water pump, a clogged radiator, or a faulty thermostat.
Solution:
Verify coolant levels and look for external leaks.
Test the thermostat: remove and test it in hot water to confirm it opens at the correct temperature.
Inspect the water pump for leaks or excessive bearing play; replace the entire pump if defective.
To prevent critical failures like the QSB6.7 overheating, implement a detailed maintenance plan:
Replace engine oil and filter strictly according to the manufacturer's schedule.
Conduct regular oil analysis to detect early wear metal contamination (a sign of bearing or piston ring failure).
Flush the cooling system annually and use only the specified heavy-duty coolant to maintain optimal heat transfer and prevent corrosion, which is vital for heavy machinery engine cooling system longevity.
