Bosch 0445120177 Common Rail Fuel Injector 5254261 for Cummins QSB Komatsu PC200-10

1. Product Overview

Brand new Bosch 0445120177 common rail fuel injector for Cummins QSB4.5 / QSB5.9 / QSB6.7 engines, Cummins OE number 5254261. The same injector is used on Komatsu PC200-10 excavators with the SAA6D107E engine (Komatsu cross number 6755-11-3100, from market listings) — the QSB6.7 and the Komatsu 6D107 share the same engine architecture, so the two applications do not conflict. No Bosch eXchange (remanufactured) number is published for this part number, so that field is left blank rather than borrowed from a neighbouring number. Nozzle note: Bosch parts data gives nozzle 0433172150 (DLLA145P2150); one technical document shows a different number, 0433172144, in a single field — that number is unconfirmed and is not used here. Bosch parts data lists two control valve numbers for this injector, F00RJ02004 and F00RJ01714 — confirm against the valve on your old injector. Neighbouring number 0445120178 serves a completely different engine family — do not cross-order.
