FAQ

Q1: Is this injector a direct replacement for the OEM Cat part 326-4700?
Yes, this injector is designed as a 100% new, direct replacement for the Caterpillar OEM part number 326-4700. It is manufactured to match the original specifications for fit, form, and function. We always recommend comparing the physical injector and your engine’s serial number to the OEM number for absolute confirmation.

Q2: What should I check before installing this injector on my Cat 320D L?
Before installation, ensure the injector part number matches your old unit (326-4700). It is critical to inspect the injector bore in the cylinder head for cleanliness and any damage. Always replace the copper washer and O-rings with new ones (not included). Torque the injector retaining clamp to the manufacturer’s specifications to prevent leaks or improper seating.

Q3: What maintenance practices can help prolong the life of the new injectors?
The life of a fuel injector is heavily dependent on fuel quality. Always use clean, high-quality diesel fuel from a reputable source. Regularly replace your fuel filters and water separator elements according to the Cat maintenance schedule. Contaminated fuel is the leading cause of injector failure, so keeping the fuel system clean is the best preventative maintenance.
