Troubleshooting Your Komatsu Fuel System (FAQ)

1. Why is my Komatsu engine experiencing hard starting or low power?
Often, this is caused by a failing fuel supply pump like the 6745-71-4330. If the pump cannot maintain consistent pressure to the injectors, the engine will struggle to ignite or maintain RPM under load. Replacing the 6745714330 pump usually restores full torque and efficiency.
2. Can a faulty 6745-71-4330 supply pump cause black smoke?
Yes. Improper fuel delivery disrupts the air-to-fuel ratio. If the supply pump provides irregular flow, it can lead to incomplete combustion, resulting in excessive smoke and carbon buildup in your cylinders.
3. How often should I replace the fuel feed pump during an overhaul?
During a major engine rebuild for Komatsu PC300 or SAA6D114E engines, replacing the supply pump is highly recommended as a preventative measure to avoid future downtime.
Why Choose This Fuel Supply Pump?
Our pumps feature an OEM-standard tri-metal structure and are trusted by professional repair shops and heavy equipment fleets worldwide.
