Bosch 0445120400 Common Rail Fuel Injector for Perkins / Caterpillar

1. Product Overview

Brand new Bosch 0445120400 common rail fuel injector (type CRIN2-16, 1600 bar) — the compatible / universal counterpart of Bosch 0445120518 for Perkins / Caterpillar applications, per the manufacturer’s technical file; this page and the 0445120518 page are linked. That file’s matching table gives the Perkins OE number T417829 for this application — a single-source reading, marked as such below (a further figure in the same table could not be read reliably and is deliberately not printed). The file names the application direction only (Perkins / Caterpillar) and lists no specific engine model, so none is stated here. One market listing pairs nozzle DLLA140P2483 with this number — single source, marked below. No Bosch exchange number or control valve has been confirmed, so those fields are left blank. Note that T417829 is a Perkins-system number; do not confuse it with Caterpillar 320-xxxx number formats.

2. Specifications

3. Fitment

Perkins / Caterpillar applications (direction documented by the technical file; no specific engine model is listed in any retrieved source, so confirm against your engine before ordering). 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 or control valve could be confirmed for this injector, so none is listed. 0445120400 and 0445120518 are related numbers for the same application family, not the same injector — the engraved Bosch number decides which one you need.
