Common Troubleshooting Tips
Question: Why is my Komatsu excavator losing hydraulic power?
Possible Causes: Low hydraulic fluid level, clogged hydraulic filters, faulty hydraulic pump, internal leaks in hydraulic cylinders or valves.
Question: How often should I change the oil in my heavy truck?
General Guideline: Oil change intervals vary depending on the truck model, engine type, and operating conditions. Consult your truck's manual, but typically it's between 25,000 to 50,000 miles for modern heavy-duty trucks using synthetic oil.
Question: What are the signs of a failing water pump in my agricultural tractor?
Common Signs: Overheating engine, coolant leaks from the pump area, noise (whining or grinding) coming from the pump, loose or wobbly pulley.
Detailed Failure and Solution: Komatsu PC200-8 Losing Engine Power
Symptom: A Komatsu PC200-8 excavator suddenly experienced a significant loss of engine power and was running erratically. The operator reported that the engine would start but lacked the usual power to perform digging operations. There were no visible leaks or unusual noises initially.
Diagnosis: After initial inspection, the fuel system was suspected. The fuel filters were checked and found to be partially clogged with contaminants. A pressure test on the common rail system revealed that the fuel pressure was significantly lower than the specified value. Further investigation pointed towards a malfunctioning Common Rail Relief Valve.
Solution: The clogged fuel filters were replaced with new ones. The Common Rail Relief Valve, part number 6754-72-1220, 6754721220, was replaced with a new original OEM Komatsu part sourced from Growshine International. After the replacement, the fuel pressure returned to the normal operating range. The excavator was restarted, and the engine power was fully restored, allowing the operator to resume normal operations. Regular maintenance of the fuel system, including timely replacement of fuel filters, is crucial to prevent such issues.
