FAQ
Q1: Will this pump fit my Caterpillar 320D excavator with a C6.6 engine?
A: Yes, this pump is designed as a direct replacement for the Caterpillar C6.6 engine used in the 320D excavator. However, we recommend verifying your existing pump’s part number (317-8021, 10R-7660, or 2641A312) to ensure a perfect match. Please check your engine serial number for confirmation.
Q2: Is this a new or remanufactured pump? What is the installation procedure?
A: This is a brand new, never-used pump. Installation should be performed by a qualified diesel mechanic. Key steps include: relieving fuel system pressure, disconnecting the battery, removing the old pump, cleaning the mounting surface, and installing the new pump with new seals and O-rings. Torque specifications must be followed precisely. We recommend consulting the Caterpillar service manual for your specific model.
Q3: What maintenance is required for this common rail pump?
A: Common rail pumps require clean fuel and proper filtration for longevity. We recommend using high-quality diesel fuel filters and changing them per the manufacturer’s schedule (typically every 500 hours). Ensure the fuel tank is free of water and contaminants. If the pump fails to prime or shows signs of wear (metal particles in the fuel), immediate inspection is required to prevent damage to injectors.
