Heavy Machinery Fault and Maintenance Guide

Fault: Engine Overheating on Komatsu PC400-6 Excavator (S6D125 Engine)

A common issue on the Komatsu PC400-6 is engine overheating, often leading to a loss of power.
Processing Solution: After checking the coolant level, the first step should be to inspect the Thermostat (Part No. 6150-61-2200). If the thermostat fails to open, coolant cannot circulate, causing rapid temperature spikes. Immediate replacement with a quality alternative from Honour Time Machinery Limited is necessary to prevent severe engine damage like a blown Gasket Head.

General Engine Maintenance Tips:

• Routine Oil Analysis: Regularly check engine oil for contaminants to predict early wear in components like the Crankshaft Bearing and Liner Kit.

• Cooling System Flush: Flush the cooling system and check the radiator every 1000 hours to ensure the Thermostat operates efficiently.

• Fuel System Integrity: Ensure your Diesel Pump and Injector Nozzles are clean and calibrated to maintain correct combustion and prevent excessive engine load.
