FAQ

Q: Is this pump a direct bolt-on replacement for my Caterpillar 320D?
A: Yes, this remanufactured pump (OEM 317-8021 / 10R-7660) is designed as a direct replacement for the original unit on the C6.6 engine found in the 320D excavator. It requires no modifications for installation. However, we always recommend comparing the physical pump and your engine’s serial number for absolute certainty.

Q: What is included in the remanufacturing process?
A: The remanufacturing process involves complete disassembly, cleaning, and inspection of all core components. Worn parts like seals, bearings, and plungers are replaced with new, OE-quality parts. The pump is then reassembled and calibrated on a test bench to ensure it meets factory specifications for fuel pressure and delivery.

Q: Do you offer technical support for installation or troubleshooting?
A: While we do not provide on-site installation services, our team can offer general technical guidance and answer questions about compatibility. We recommend that installation be performed by a qualified diesel mechanic familiar with Caterpillar common rail systems to ensure proper setup and avoid damage.
