Caterpillar original Diesel Fuel Injector 293-4573 for Excavator C7 Engine 324D 325D 330D 336D, Cross Reference 10R2828, Replacement for OEM 267-9717 original new injector

Built for Caterpillar C7 series diesel engine platforms, with documented aftermarket references to select C7/C9 configurations, the 293-4573 diesel fuel injector is an industrial-grade precision component engineered to meter, atomize, and deliver diesel fuel directly to the combustion chamber. It supports stable power output, optimized fuel efficiency, balanced combustion, and consistent emission performance, and is stocked to serve B2B buyers including diesel parts distributors, fleet maintenance teams, engine rebuilders, repair shops, and industrial procurement specialists.

The assembly’s primary OE number is 293-4573, with common search variants including 2934573, CA2934573, and 293 4573. It is associated with common cross-reference numbers 10R-4763, 20R-8059, 20R-8057, 243-4503, 295-1411, 268-9577, and 20R-8071, but final fitment must be verified against engine serial number, machine model, original injector number, and injector code before ordering, as CAT parts vary by configuration, emissions tier, and machine arrangement.

When matched to the correct engine configuration, the injector fits a wide range of diesel-powered Caterpillar equipment including excavators, wheel loaders, bulldozers, trucks, buses, generator sets, marine auxiliary engines, agricultural machinery, mining equipment, and stationary industrial power units. It supports smooth idling, reliable cold starts, reduced smoke, lower unplanned downtime, and long durability for heavy-duty workloads.
