0445120177 BO-SCH Original Common Rail Injector 5254261 For Cum-mins QSB6.7

0445120177 Original Common Rail Injector For Cum-mins QSB

The 0445120177 common rail fuel injector, also written as 0 445 120 177, is a Bo-sch OE diesel injector used in selected Cum-mins QSB applications. Bo-sch officially identifies 5254261 as the corresponding OE number, while Bo-sch's current injector service documentation classifies 0445120177 as a CRIN3-18 common rail injector.

As an original genuine injector, it is supplied with original BO-SCH label and packing.

Professional Bo-sch diesel application data identifies QSB4.5, QSB5.9 and QSB6.7 applications. The injector is therefore useful for customers searching by Bo-sch number, Cum-mins number or QSB engine family. Because multiple common rail injector variants exist across Cum-mins QSB generations, the original injector number remains the preferred method of identification.

Product Specifications

Bo-sch's own diesel cross-reference catalogue also maps Komatsu part number 5254261 to Bo-sch 0 445 120 177, making 5254261 useful for both Cum-mins and selected Komatsu equipment-parts searches.
