FAQ

Q1: Is this pump a direct replacement for my Caterpillar 320 excavator?

Yes, this pump (326-4635 / 10R-7662) is designed as a direct OEM replacement for the Caterpillar 320 excavator. It is a bolt-on component that matches the original specifications. We recommend verifying your existing pump’s part number to confirm fitment.

Q2: What should I check before installation?

Before installation, ensure the fuel system is clean and free of contaminants. Check the high-pressure fuel lines and injectors for wear, as a faulty pump can be caused by debris from other failing components. It is also recommended to replace the fuel filter and use clean, high-quality diesel fuel.

Q3: How can I maintain this fuel injection pump for a longer service life?

Regular maintenance is key. Use only clean, high-quality diesel fuel and replace fuel filters at the intervals specified by Caterpillar. Avoid running the fuel tank low, as this can introduce air and debris into the system. If the engine shows signs of poor performance (hard starting, loss of power, black smoke), have the fuel system inspected by a qualified technician promptly.
