Bosch 0445120518 Common Rail Fuel Injector for Perkins / Caterpillar (Universal Number for 0445120400)

1. Product Overview

Brand new Bosch 0445120518 common rail fuel injector — the compatible / universal counterpart of Bosch 0445120400. The manufacturer’s technical file for 0445120400 lists this number as its compatible number, so this page follows the main number’s documented application direction: Perkins / Caterpillar engines, with Perkins OE number T417829 carried over from the main number’s matching table. That OE reading rests on that one technical file only and is marked single source wherever it appears below — treat it as to be confirmed, not as settled. The two pages are linked. This number’s own nozzle, control valve and exchange number have no per-number source and are left blank. One caution: a marketplace listing bundles this number together with 0445120519, but 0519 has no file record of its own — the bundle does not make this page’s OE data apply to 0519, and the two numbers must not be confused. Always order by the exact Bosch number engraved on your old injector.

2. Specifications

3. Fitment

Perkins / Caterpillar engines — the documented application direction of main number 0445120400, for which this number is the compatible / universal counterpart; market listings associate this number group with Caterpillar C4.4 engines (320D2 machines). Fitment data is for reference only — please confirm by the number engraved on your old injector or send us your VIN before ordering.

4. Cross-Reference

Note: no Bosch exchange number, nozzle or control valve could be confirmed for this number itself, so none is listed. The main number’s matching table also contains one incomplete, garbled reading alongside T417829; it is not reproduced here and must not be used as a part number. Nothing on this page applies to 0445120519, which appears with this number in one seller’s bundle but has no documentation of its own.
