This is the Bosch 0432191794, a new mechanical fuel injector supplied as a complete nozzle and holder assembly for the Cummins C Series 8.3L (6CT) with mechanical injection, the engine Case calls the 6T-830 or 6TA-830. It is the Bosch-made injector behind Cummins 3908513 and Cummins service number 3802091, and CNH sells it as J908513. Catalogs list it for the Case IH 1688 and 2188 Axial-Flow combines and the 2155 cotton picker. It is not an injector for the electronic common-rail ISC or QSC.

Worn mechanical injectors on the 8.3L show up as hard starting, a rough idle, black smoke under load, fuel knock or fuel in the oil, and a pop test shows a low opening pressure or a poor spray pattern. Check the lift pump, filters and pump timing first. Replace all six together so the cylinders stay even, and never mix opening pressures in one engine. It is one of the low-pressure injectors of the family: it opens at 205 to 219 bar, about 3,100 psi.

Specifications

Fits / Applications

• Cummins C Series 8.3L (6CT) with mechanical injection
• Case IH 1688 Axial-Flow combine
• Case IH 2188 Axial-Flow combine and 2155 cotton picker, on machines that list J908513 (they used both this injector and the 0432191632, depending on serial number)
• Engines that call for Cummins 3908513 or 3802091 or CNH J908513
• Not for common-rail ISC or QSC 8.3L engines
• Six injectors per engine

Fit a new sealing washer under each nozzle, clean the injector bore and seat, and cap the lines until they go on. Torque the hold-down to the engine maker’s figure, bleed the high-pressure lines, then check for leaks and an even idle.

Frequently Asked Questions

What numbers does the Bosch 0432191794 replace?

Cummins 3908513 and 3802091 (which replaced 3802099) and CNH J908513. Catalogs also cross it to the older Case IH kit number A77700.

Will it fit my Case IH 2188 combine?

It depends on the serial number. Catalogs list the 2188 with both this 3,100 psi injector and the 4,500 psi 0432191632. Check the number on your old injector or call 530-668-0818 with the combine serial number.

How is it different from the 0432191595 and 0432191632?

Opening pressure. The 0432191794 opens at 205 to 219 bar, the 0432191595 at 260 to 274 bar and the 0432191632 at 300 to 314 bar, so fit only the one your engine lists even though they look the same.

Is it new, and is there a core?

It is a new Bosch injector, not a rebuild, and it is sold outright with no core to return.
