FAQ

Q1: Will this injector fit my Caterpillar 3126B engine without modifications?
Yes, this injector (part numbers 177-4754 / 1774754 / 2225972) is a direct OEM replacement designed for the 3126 and 3126B engines. No modifications are required. However, we recommend cross-checking your engine’s serial number and existing injector part number to ensure compatibility.

Q2: What is the recommended installation procedure for this remanufactured injector?
Installation should be performed by a qualified diesel technician. Key steps include: cleaning the injector bore, using new copper washers and O-rings (not included), torquing to manufacturer specifications, and bleeding the fuel system after installation to remove air. Failure to follow proper procedure may void the warranty.

Q3: How do I maintain these injectors to maximize their lifespan?
