Recommended chain: 0445120177 / 5254261 → Engine Model → ESN → CPL → Equipment.

Do not identify the injector simply as "Cum-mins QSB6.7 injector". We now already have several distinct QSB6.7 injector nodes, and those should remain separate.

Equipment Application

Hyundai HL730-9A, HL730TM-9A and R250LC-9A appear in aftermarket databases using Cum-mins 6.7L ISB / QSB engines. These are published as Secondary / Market Application and should still be confirmed by injector number or machine / engine serial data. Komatsu 5254261 is a Bo-sch cross-reference catalogue mapping for 0 445 120 177, useful for selected Komatsu equipment-parts searches.
