Perkins original  10R-0725 Fuel Injector 10R0725 10R9235 212-3464 Replacement for CAT Excavator Truck Engine Spare Parts original new injector

The Perkins 10R-0725 10R0725 reman fuel injector is engineered as a direct OE replacement for Perkins C10, C12, 3176, 3176C, and 3196 diesel engines used in heavy-duty trucks, industrial power units, and marine applications. Authorized cross references include 212-3464, 212-3462, 10R-0967, 166-0153, 161-1785, 116-5414, CH-12082, EX630725, CA10R0725, CA2123464, and CA1660153, providing broad interchangeability across Perkins 3176C and 3196 industrial and marine engine platforms as well as C10 and C12 on-highway truck installations such as Freightliner Condor, Sterling Truck Condor, Peterbilt 385, Peterbilt 320, Peterbilt 357, Western Star 4900SA, 4900FA, and International Harvester 5600i. Official listed dimensions are 14.8 inches length and 3.0 inches height.

The injector assembly delivers precision fuel metering, controlled spray pattern, high-pressure durability, and stable atomization to restore engine power, reduce rough idle, improve combustion quality, lower smoke output, and support better fuel economy. Nozzle flow matching helps maintain cylinder balance, while new sealing components reduce leakage risk. Each unit is calibrated to deliver the correct diesel fuel volume at the correct timing, pressure, spray angle, and atomization pattern specified for the Perkins 10R-0725 platform.

Before installation, technicians should confirm the injector part number, engine serial number, old injector number, injector trim code, and engine configuration. Clean the injector bore, fuel lines, and sealing surfaces; replace O-rings, washers, and injector seals; lubricate O-rings with clean engine oil; inspect the bore for carbon, corrosion, scoring, or sleeve damage; and use only torque values from the correct Perkins service manual. After installation, prime the fuel system, then check for leakage, misfire, smoke, rough idle, and diagnostic fault codes. Use clean diesel fuel meeting engine manufacturer requirements, replace fuel filters on schedule, drain the water separator regularly, and store injectors in sealed, dry, clean packaging.
