Precision-engineered for Caterpillar C7 engine platforms operating in demanding heavy-duty conditions, the 1OR-4763 diesel fuel injector is a core component of the CAT C7 ACERT electronic fuel delivery system. Compatible with all C7 variants including industrial, generator, marine, and truck models, it fits heavy equipment across construction, power generation, vocational transportation, and marine sectors. Recognized across global OEM and aftermarket networks, it features OEM-matching fit and function to eliminate compatibility risks for B2B buyers, fleet operators, and repair providers.

Manufactured in strict accordance with OEM specifications, this electronically controlled injector receives real-time fuel demand signals from the engine ECM based on parameters including speed, load, air and fuel temperature, and boost pressure. It uses precise injection timing and micro-machined nozzle holes to atomize high-pressure diesel into ultra-fine droplets for optimized combustion, improving fuel economy, reducing NOx and particulate matter emissions, boosting power output, sharpening throttle response, and extending engine service life to cut long-term operating costs.

Every unit passes 100% factory quality testing, and is available in new or remanufactured condition with a 1-piece minimum order quantity. Delivery takes 3–15 working days, with neutral carton or custom branded packaging and flexible global shipping options via express, air freight, or sea freight to meet diverse operational needs. All injectors come with a 12-month warranty, making them a reliable choice for parts distributors, equipment repair shops, and fleet maintenance teams.
