This is the Bosch 0432133775, a new mechanical fuel injector supplied as a complete nozzle and holder assembly. It is the Bosch-made injector behind CNH part number 2852273 and Iveco part number 504063465. Catalogs list it for the Iveco-built NEF mechanical (pump, line and nozzle) diesel in both sizes, the 4.5L four-cylinder (Case 445T/M2) and the 6.7L six-cylinder. Machines include the Case 521D and 621D wheel loaders, Case IH Maxxum MXU130 and Farmall 125A and 140A tractors, Case IH WDX1202 windrowers, New Holland TS6.125, TS6.140 and TS6030 tractors, the LM435A telehandler, LB90.B and LB115.B loader backhoes and LW130.B, W110 and W130 wheel loaders. It is not a common-rail injector and it has no electrical connector.

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.

Specifications

Fits / Applications

• Iveco / FPT NEF mechanical engines, 4.5L four-cylinder and 6.7L six-cylinder, that list injector 2852273 or 504063465
• Case 521D and 621D wheel loaders with the Iveco-built engine
• Case IH Maxxum MXU130 tractor
• Case IH Farmall 125A and 140A tractors (catalogs list more than one injector on these tractors, so match the number)
• Case IH WDX1202 and WDX1202S self-propelled windrowers
• New Holland TS6.125, TS6.140 and TS6030 tractors, and 6610S tractors of the Latin America build with the Iveco-built engine
• New Holland LM435A telehandler and LB90.B loader backhoe (CNH also lists 2852869, Bosch 0432133779, on these two, so match the number)
• New Holland LB115.B loader backhoe (built from 2003) and BW28 bale wagon
• New Holland LW130.B, W110 and W130 wheel loaders
• McCormick tractors that list injector 705179A1, 713844A1 or 713944A1
• Mechanical injection engines only, not common rail
• Many of these machines used more than one injector over the years: match 2852273, 504063465 or 0432133775 on your old injector or in the parts book

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 0432133775 replace?

It is the Bosch injector sold by CNH as 2852273 and by Iveco as 504063465. Catalogs also cross it to McCormick 705179A1, 713844A1 and 713944A1.

Will it fit my Case 521D or 621D wheel loader?

Catalogs list it for the 521D and 621D with the Iveco-built 4.5L or 6.7L engine. CNH splits the parts books for these loaders at serial number JEE0135500 and they used more than one injector, so check that your parts book or old injector shows 2852273, 504063465 or 0432133775 before you order.

Is the 0432133775 the same as the 0432133780 or 0432133761?

They are three different Bosch part numbers and CNH sells each under its own number: 0432133775 is 2852273, 0432133780 is 2852056 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. It is sold outright, so there is no core to send back. Call 530-668-0818 with the machine model and serial number if you want us to check the match.
