FAQ

Q: How do I confirm this injector (387-9430 / 10R-4761) fits my engine?
A: This injector is specifically designed for the Caterpillar C7 engine. To guarantee a perfect match, please compare the part number on your old injector with 387-9430 or 10R-4761. You can also check your engine serial number and consult your vehicle’s parts manual for the correct injector code.

Q: What is involved in installing a remanufactured injector?
A: Installation should be performed by a qualified diesel mechanic. The process involves removing the valve cover, disconnecting the fuel lines and electrical connector, removing the old injector, cleaning the injector bore, lubricating the new injector’s O-rings, and installing it to the correct torque specifications. It is highly recommended to replace the injector hold-down bolts and copper washers.

Q: What maintenance is required for this common rail injector?
A: The most important maintenance is ensuring a clean fuel supply. Always use high-quality diesel fuel and replace your fuel filters at the intervals specified by the engine manufacturer. Contaminated fuel is the primary cause of injector failure. There is no user-serviceable maintenance for the injector itself; if it fails, it must be replaced.
