This is the Bosch 0445120194, a new genuine Bosch CRIN 4.2 common-rail injector, not a rebuild, for the Detroit Diesel DD13 12.8L. It replaces Detroit injectors A4710700387, A4710700287 and A4710700187 and matches Detroit kits EA4600701187 and RA4600701187, which Detroit lists for EPA07 and EPA10 DD13 engines. Catalogs date it to 2008 to 2014 engines, the DD13 found in the Freightliner Cascadia and other Freightliner and Western Star trucks. Bosch also offers the same injector remanufactured as 0986435738.

A rough idle, a miss under load, hard starting, fuel in the oil, white or black smoke and cylinder balance faults are the usual reasons these injectors come out. Check fuel supply, filters and rail pressure first, because a weak supply side gives the same complaints. The engine takes six injectors, and worn sets are normally changed together. Each injector carries its own calibration code, which has to be programmed into the engine controller after fitting.

Specifications

Fits / Applications

• Detroit Diesel DD13 12.8L inline six, EPA07 and EPA10 builds (Detroit kit RA4600701187 / EA4600701187)
• Engines built with Detroit injector A4710700387, A4710700287 or A4710700187
• Catalogs date it to DD13 engines built through 2014
• Trucks: Freightliner Cascadia, Coronado, 114SD, 122SD and M2 112, Western Star 4700, 4800, 4900 and 5700XE, where built with this DD13. Match by engine build, not by truck.
• Also catalogued for the Mercedes-Benz OM471 12.8L, the same engine family outside North America
• Later DD13 builds are listed with other injectors: A4710700487 (Bosch 0445120270 / 0986435739) and, on GHG17 engines, A4710701387 (Bosch 0986435741)
• The DD15 14.8L and DD16 15.6L take their own injectors
• Six injectors per engine, sold each

Match the Detroit or Bosch number on the old injector before fitting. Each injector carries its own calibration code, which has to be programmed into the engine controller after fitting. Catalogs list this injector with its body O-rings and nozzle sealing washer. The hold-down bolt and injector tube gasket that Detroit packs in its own kit are not in the Bosch box: catalogs sell them as an add-on kit (Alliant Power AP0145), one per injector, so ask about it when you order. Keep everything clean, fit new fuel filters, and cap open lines and ports while the injectors are out, because common-rail injectors do not tolerate dirt.

Frequently Asked Questions

Will the 0445120194 fit every Detroit DD13?

Not by Detroit’s catalog. It lists this injector (kit EA4600701187) for EPA07 and EPA10 DD13 engines built with A4710700387, A4710700287 or A4710700187, and other kits for later builds: A4710700487 and, on GHG17 engines, A4710701387. Call 530-668-0818 with your engine serial number if you are not sure.

What numbers does the 0445120194 replace?

Detroit injectors A4710700387, A4710700287 and A4710700187 and Detroit kits EA4600701187, RA4600701187 and EA4600700687. Its twin Bosch number is 0445120195, and the matching Bosch remanufactured numbers are 0986435738, 0986435537 and 0986435642.

Is the 0445120194 new or remanufactured?

It is a new genuine Bosch injector. The Bosch remanufactured version of the same injector is 0986435738.

Does the 0445120194 need coding, and what else do I need to fit it?

Yes. Each injector has a calibration code that is programmed into the engine controller after fitting. The hold-down bolt and injector tube gasket are not in the Bosch box, so plan on one add-on kit (Alliant Power AP0145) per injector.
