Caterpillar original 295050-0401 295050-0400 diesel fuel injector 295-050-0401 common rail injector for CAT 320D engine part  original new injector

The Original DENSO 295050-0401 Common Rail Injector is engineered to deliver precise fuel delivery and consistent spray atomization for Caterpillar C4.4, C6.6, and C7.1 diesel engines. Built to OEM specification, this injector integrates seamlessly into the diesel common rail fuel injection system, ensuring stable rail pressure, optimized combustion efficiency, and reduced exhaust emissions across demanding operating cycles. It is a direct-fit replacement for CAT part numbers 370-7282 and 20R-2478, providing reliable interchangeability for service, overhaul, and remanufacturing applications.

Designed for Caterpillar 320E and 323E excavators, as well as generator sets, loaders, and broader construction, agricultural, and industrial equipment platforms, this unit supports a wide range of heavy-duty applications. The precision-machined nozzle assembly, high-grade solenoid valve, and hardened internal components ensure durability under high injection pressures and continuous load conditions. Each injector is manufactured under strict quality control standards to meet or exceed original equipment performance benchmarks.

Prior to installation, verify the OE number, engine serial number, and fuel system condition, and replace the injector seal kit and contaminated fuel filter as required. During installation, clean the injector bore, install a new copper washer, apply the OEM torque specification, and confirm the electrical connector lock. After installation, bleed the fuel system, clear ECU fault codes, perform injector coding and idle calibration, and conduct a leak test to verify proper operation.
