Caterpillar original Common Rail Diesel Fuel Injector for C4.4 C7.1 Engine, 295050-0401, 295050-0331, Replacement for OEM 295050-2400, 370-7282, Compatible with 320F Excavator original new injector

Built for cross-network B2B parts procurement and heavy equipment maintenance use cases, the CAT 295050-0331 high-pressure common rail diesel injector is a precision-engineered component compatible with Caterpillar C4.4 and C7.1 engine platforms, with verified fitment for select Perkins engine configurations via cross-reference. Its full set of validated OE and cross numbers supports seamless matching across CAT service networks, remanufacturing providers and global supplier databases, eliminating fitment errors for dealers, repair shops and equipment fleet operators.

Constructed from high-strength alloys with CNC-machined components and multi-hole hardened nozzles, the injector is OEM-calibrated to deliver stable, repeatable fuel delivery under 1,800–2,200 bar common rail pressure. Controlled by ECU signals for precise injection timing and duration, it atomizes diesel into fine droplets to optimize combustion, reduce emissions, improve fuel economy and maintain consistent torque output even under sustained heavy-duty operating conditions.

Each unit undergoes industrial-condition testing prior to release to ensure long-term reliability. For optimal service life, installers must clean the fuel system, replace seals, verify torque settings and run diagnostic scans post-installation; routine maintenance includes regular filter replacement, fuel quality monitoring, periodic return flow testing and checks for common injector faults including rough idle, reduced power, abnormal smoke and high fuel consumption. It is validated for use across global construction, mining, power generation, agriculture and infrastructure equipment fleets to reduce unplanned downtime.
