617-1905 CAT-ERPILLAR COMMON RAIL FUEL INJECTOR FOR C9.3B 336 340

617-1905 CAT-erpillar Common Rail Fuel Injector

617-1905 is an engine fuel injector designed for C9.3 and C9.3B common rail diesel fuel systems. It meters, atomizes and injects high-pressure diesel fuel into the combustion chamber according to the engine control strategy. Accurate fuel delivery supports stable combustion, engine output and fuel efficiency.

The main product number is 617-1905, which can also be written without the hyphen as 6171905. Cat officially lists 30R-0718 as the related remanufactured common rail injector. The earlier number 510-1695 is identified as a C9.3B LRC common rail fuel injector and is currently shown as discontinued.

Independent Bo-sch and aftermarket catalogues associate 617-1905 with Bo-sch injector number 0445120730, also written as 0 445 120 730. Because this Bo-sch relationship is not displayed directly on the Cat product page, it should be presented as a Bo-sch reference or cross-reference rather than an exclusive official replacement declaration.

The official Cat compatibility list includes C9.3 and C9.3B engines, 336, 340, 350 and 345 GC excavators, 966, 966 GC and 972 wheel loaders, 973 and 973K track loaders, D6 and D7 tractors, RM400 reclaimers and PM310, PM312 and PM313 cold planers. Generator and mobile hydraulic power applications are also listed.

Machine model alone cannot guarantee compatibility. Different serial-number ranges, emission configurations and engine arrangements may use different injectors. Final confirmation should be based on the old injector number, engine serial number, machine serial number or a clear label photo.
