Caterpillar original Diesel Engine Fuel Injector Cross Reference 387-9433, 328-2574, 263-8218, Fuel Injector 293-4071 Replacement for OEM Compatible with Caterpillar C7 C9 original new injector

For procurement and maintenance teams managing Caterpillar heavy-duty assets, the 293-4071 (alternately searched as 2934071) is a high-precision diesel fuel injector purpose-built for CAT C9 engine fuel systems. Aligned with official Caterpillar parts design requirements, it delivers accurately metered diesel fuel into the combustion chamber at precise timing, and is engineered to work with modern low-sulfur diesel fuels for consistent, reliable operation in demanding work conditions.

This injector is designed for Caterpillar C9 series diesel engines, including C9 ACERT-related applications, and fits common CAT equipment models including D6R and D6T track-type tractors, E330D and E336D excavators, as well as all other C9-powered construction, mining and industrial machinery. It is associated with a full set of public cross-reference identifiers for streamlined supply chain matching, reman sourcing and aftermarket quotation, though these numbers are only fitment leads and require final validation via engine serial number, machine serial number, old injector number and engine arrangement data.

It is available in multiple condition options (including original new, OEM type, aftermarket replacement and remanufactured units) and flexible packaging choices to support distributors, repair workshops, engine rebuilders, fleet maintenance teams and equipment owners. The component addresses core B2B buyer priorities including correct part fitment, proper injector calibration, steady fuel economy, verified quality, warranty support and reliable delivery to reduce heavy equipment downtime.
