Perkins original  10R-1258 Diesel Fuel Injection Pump Injector Assembly 212-3462 10R-0967 212-3465 10R-0961 212-3468 for C12 Truck Engine new injector original new injector

The Perkins Fuel Injector 10R-1258 is engineered as a direct OEM replacement for Perkins C10 and C12 diesel engine platforms, delivering factory-grade fuel injection performance across industrial, marine, and power generation applications. Built to original Perkins specifications, this injector assembly carries the authorized OE number 10R-1258 alongside the cross reference 212-3468, allowing distributors, fleet operators, and service shops to source the correct component without ambiguity. Each unit is manufactured with industrial-grade hardened steel components and corrosion-resistant internal parts, ensuring dependable operation under the heavy-load conditions typical of excavators, loaders, generator sets, and marine propulsion systems.

Precision calibrated fuel delivery enables improved fuel atomization and higher combustion efficiency, resulting in increased engine power output, reduced fuel consumption, and lower exhaust emissions. The high-pressure diesel injection capability supports stable engine operation across a wide duty cycle, from continuous generator runtime to intermittent construction equipment use. Every injector is assembled to OEM specification tolerances, which contributes directly to extended service life and reduced downtime in demanding field environments where reliability is a critical purchasing factor for B2B buyers.

Proper installation is essential to achieve rated performance. Technicians should always clean the injector bore before installation, replace all sealing washers and O-rings, and apply calibrated torque tools to specified values. The fuel system must be primed prior to startup, followed by a leak inspection to confirm integrity. Operators are advised to use clean diesel fuel, replace filters at regular intervals, avoid water contamination, monitor fuel pressure routinely, and conduct periodic injector testing. These maintenance practices help prevent common fault conditions including fuel injection failure, cylinder misfire, fuel pressure imbalance, injector circuit malfunction, and poor combustion efficiency.
