Bosch 0445120371 Common Rail Fuel Injector for Caterpillar C7.1 / Perkins

1. Product Overview

Brand new Bosch 0445120371 common rail fuel injector (type CRIN2-16) for Caterpillar C7.1 engines and the Perkins equivalent platform. This injector and 0445120382 form a documented pair: market listings from several independent suppliers consistently list the two Bosch numbers together against the same OE set — Caterpillar 396-9626, Perkins T413609 and Caterpillar remanufactured number 20R-4561 — and this number’s own technical file reads PERKINS / CATERPILLAR and adds compatible Bosch number 0445120520. No source splits the OE set between the two Bosch numbers, so both OE numbers are shown on both pages at pair level. The pair are not blindly interchangeable: which of the two your engine needs is decided by the Bosch number engraved on your old injector. Note that 20R-4561 is a Caterpillar remanufactured number, not a Bosch exchange number — no Bosch exchange number has been confirmed for this injector, and nozzle / control valve values could not be retrieved in this round, so those fields are left blank. Similar Cat-format numbers in this range belong to other Bosch numbers — do not transfer them to this one.

3. Fitment

Caterpillar C7.1 engines (including CAT 330 / 330D / 333 / 336 excavators) and the Perkins equivalent platform. This number and 0445120382 share the same documented application — confirm which Bosch number your engine carries by the engraving 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: the OE set above is documented at pair level for 0445120371 + 0445120382 together; no source assigns one OE to one Bosch number only, so both are listed on both pages. No Bosch exchange number, nozzle or control valve could be confirmed for this injector, so none is listed.
