Caterpillar original  222-5967 2225967 C9.3 E336E Excavator Parts Fuel Injector 20R-5075 460-8213 456-3509 20R5075 4563509 Replacement for OEM original new injector

The Caterpillar C9.3 Fuel Injector 222-5967 is a precision-engineered common rail fuel injector designed to deliver consistent and efficient fuel atomization for the CAT C9.3 engine platform. Manufactured to OEM equivalent dimensional and performance standards, this injector ensures accurate fuel metering under varying load conditions, supporting improved fuel economy and reduced exhaust emissions across heavy-duty applications. Constructed from high-grade alloy steel with corrosion-resistant properties, the 222-5967 injector is built to withstand prolonged exposure to high-pressure combustion environments while maintaining stable injection performance.

This injector is fully compatible with C9.3 ACERT, C9.3 Industrial, and C9.3 Generator Engine configurations, integrating seamlessly with the electronic fuel injection and high-pressure common rail systems. It serves as a direct replacement for part number 328-2574, providing reliable service across excavators, wheel loaders, motor graders, soil compactors, material handlers, mining equipment, industrial power units, generator sets, and auxiliary marine engines. Each unit is calibrated to deliver consistent spray patterns and balanced fuel delivery, supporting optimal engine response in demanding operating environments.

Routine maintenance of the 222-5967 injector includes regular inspection of fuel filters, use of ultra-clean diesel to prevent contamination, and periodic testing of injector balance rates. Technicians should verify fuel rail cleanliness, inspect nozzle seat condition, and replace sealing washers and O-rings during servicing. Post-installation checks should include torque verification, ECM diagnostic validation, and inspection for fuel leakage. When symptoms such as hard starting, black smoke, or power loss occur, the injector flow rate, spray pattern, and electronic control signals should be examined to confirm proper operation within the C9.3 fuel system.
