This is the Bosch 0986435737, a CRIN 4.2 common-rail fuel injector remanufactured by Bosch for the Detroit Diesel DD15 14.8L and DD16 15.6L. It takes the place of the injector in Detroit kit RA4600701087, which Detroit lists for EPA07, EPA10 and GHG14 engines, and of Detroit A4720700887. The earlier Bosch remanufactured numbers for the same injector are 0986435539 and 0986435540, and the new Bosch versions are 0445120207 and 0445120104. Catalogs list it for Freightliner Cascadia, Coronado, Columbia, Century Class and 122SD, Western Star 4900 and 5700XE and Sterling A9500 and L9500 trucks. The engine takes six injectors. A refundable core applies.
A miss under load, hard starting, smoke, fuel in the oil or a cylinder cutout test that points at one hole are the usual reasons these get replaced. Change the fuel filters at the same time, since dirty fuel is what wears these injectors out.
Confirm Fitment Before You Order
Detroit lists two injector kits for the DD15 and DD16. This injector matches kit RA4600701087, for EPA07, EPA10 and GHG14 engines. GHG17 engines take kit RA4600701387, Bosch 0986435740. DD13 engines take other Bosch injectors. Send us the engine serial number (ESN) and the Detroit and Bosch numbers from your old injector. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
