Caterpillar original 267-9734 Common Rail Diesel Fuel Injector 10R9002 for C9 Engine E330D E336D E340D D6R III D6T 511 160M Excavator original new injector

The 267-9734 Caterpillar C9 fuel injector is a precision-engineered electronic fuel injection component manufactured to OEM equivalent standards for the CAT C9 diesel engine platform. Constructed from high-strength alloy steel and individually factory tested, this injector delivers consistent high-pressure fuel atomization that improves combustion performance, enhances fuel economy, and lowers exhaust emissions. It integrates seamlessly with the engine control module for precise electronic metering across varying load and speed conditions, supporting reliable heavy-duty operation in construction, power generation, and marine service environments.

This fuel injector cross-references directly with part numbers 10R-7675, 10R7675, 328-2574, 3282574, and 2679734, making it a versatile replacement option for fleet operators and service workshops maintaining CAT C9 and C9 ACERT engines. Its optimized nozzle geometry and robust solenoid design improve cold-start performance while extending overall injector service life, which reduces maintenance costs and equipment downtime in demanding applications including hydraulic excavators, wheel loaders, motor graders, compactors, dozers, articulated trucks, generator sets, and marine propulsion engines.

Proper installation following CAT service procedures and the use of clean diesel fuel are essential to maintain injector performance and longevity. Routine diagnostics such as return flow analysis, electronic fault code scanning, cylinder balance testing, and fuel pressure verification help detect early signs of injector wear, ensuring continued reliability and efficient operation of CAT C9 powered equipment throughout its service life.
