FAQ

Q1: Is this injector a direct replacement for the original Caterpillar part on my 320D?
Yes, this injector (320-0677) is a direct OEM replacement designed for the Caterpillar 320D excavator equipped with the C6.4 or C6.6 engine. It matches the physical dimensions, connector type, and fuel flow specifications of the original part, requiring no modifications for installation.

Q2: What is the recommended installation procedure for this injector?
Installation should be performed by a qualified diesel technician. Ensure the injector bore in the cylinder head is clean and free of debris. Always replace the copper washer and O-rings with new ones. Tighten the injector clamp to the manufacturer’s specified torque to prevent fuel leakage and ensure proper sealing. After installation, prime the fuel system and check for leaks before starting the engine.

Q3: How can I confirm this injector will fit my specific engine?
To confirm fitment, please check your engine’s serial number against the C6.4 or C6.6 series compatibility. You can also verify the existing part number on your current injector. If it matches 320-0677, 3200677, or 2465A746, this unit is the correct replacement. If you are unsure, please contact us with your engine serial number and machine model for verification.
