Product Specification

0445120177 Remanufactured Injector For Cum-mins QSB

This remanufactured common rail fuel injector is supplied as a replacement for applications identified by 0445120177 / 0 445 120 177 and Cum-mins OE number 5254261. Bo-sch's original injector specification belongs to the CRIN3-18 family, while professional diesel application data covers Cum-mins QSB4.5, QSB5.9 and QSB6.7 engines. The primary Bo-sch remanufactured reference is 0986435697, which Bo-sch officially associates with OE 5254261. Cum-mins exchange references such as 5254261NX, 5254261PX and 5254261RX also appear within the same service family.

Each unit is disassembled, cleaned, inspected and rebuilt to original specifications with new wear parts where required, then 100% tested for injection pressure, spray pattern and leak-tightness before shipment.

Correct Part Identification

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.
