Perkins original Engine Common Rail Fuel Injector 153-7923 10R-0963 208-9160 317-5278 223-5328 350-7555 Replacement for OEM  original new injector

The Perkins C12 Fuel Injector 153-7923 is engineered as a direct OEM equivalent replacement for diesel power applications requiring consistent fuel delivery and stable combustion performance. Designed to match the original specifications of the Perkins C12 engine platform, this injector supports an inline 6-cylinder configuration with 11.9-liter displacement and electronic unit injection, covering a power range of 300HP to 525HP. It is fully compatible with Perkins C12, 3176, and 3176B engines used across on-highway trucks, industrial machinery, marine propulsion, and power generation sets, including Challenger 75C, Challenger 85C, and E345B excavator equipment.

This fuel injector assembly cross-references multiple authorized part numbers, including 153-7923, 0R-9595, 10R-7251, 235-1545, CAT1537923, CAT2351545, CAT10R7251, CAT0R9595, CA1537923, CA2351545, CA10R7251, CA0R9595, R0R9595, EX0R9595, FS0R9595, and 3176B, providing dependable interchangeability for replacement, remanufacturing, and service operations across the global aftermarket. The injector is built to deliver high fuel efficiency, reduced emissions output, and long service life under heavy-duty operating conditions typical of construction, mining, marine, and agricultural applications.

Prior to installation, technicians should inspect the injector bore, injector cup, fuel line cleanliness, electrical connector condition, and fuel pressure stability to ensure proper operation. The use of high-quality diesel fuel, OEM-equivalent fuel filters, and routine water separator maintenance is recommended to preserve injector performance. Scheduled fuel system diagnostics further extend component longevity and maintain stable engine power across demanding industrial, truck, marine, and power generation environments.
