This is the Bosch 0432133780, a new mechanical fuel injector supplied as a complete nozzle and holder assembly. It is the Bosch-made injector behind CNH part number 2852056 and Iveco part number 500390441, used on the Iveco-built NEF mechanical (pump, line and nozzle) diesel, mostly the 4.5L four-cylinder. Catalogs list it for the Case 435, 440, 450 and 465 skid steers and 440CT and 450CT compact track loaders built before the Series 3 (Tier 3) serial number breaks, the Case 590 Super M Series 2 loader backhoe, New Holland L185, LS185.B, C185 and LT185.B loaders, Case IH JX1090U, JX1095C, JX1100U, Maxxum MXU100 and Farmall 110A tractors, and New Holland TS100A, TL90A, TL100A, TN95A and TN95DA tractors. It has no electrical connector and it is not a common-rail injector.

Mechanical injectors wear at the nozzle. Hard starting, a rough idle, black or white smoke, fuel knock and fuel in the oil are the usual signs, and a pop test shows a low opening pressure or a poor spray pattern. Bosch sets this injector to open at 260 to 272 bar. Check the lift pump, filters and injection pump timing before you blame the injectors, and replace them as a full set so the cylinders stay even.

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

Will the Bosch 0432133780 fit my Case 440 or 450 skid steer?

It fits the earlier machines. CNH lists injector 2852056 for the North American Case 440 before serial number N8M474469 and for the Tier 2 Case 450. Series 3 (Tier 3) machines take CNH 2856255, which is Bosch 0432133761, so check the serial number or the number on the old injector before you order.

What numbers does the 0432133780 replace?

CNH 2852056 and Iveco 500390441. It is the same Bosch-made injector those numbers are sold under.

Is the 0432133780 the same as the 0432133775 or 0432133761?

They are three different Bosch part numbers and CNH sells each under its own number: 0432133780 is 2852056, 0432133775 is 2852273 and 0432133761 is 2856255. We cannot confirm that one replaces another, so order by the number your machine calls for.

Is it new or remanufactured, and is there a core?

It is a new Bosch nozzle and holder assembly, not a rebuild, and it is sold outright with no core to return. Call 530-668-0818 with your machine model and serial number if you want us to check the match.
