The Bosch 0432133761 is a new, genuine Bosch mechanical fuel injector, a complete nozzle and holder assembly. It is used on Case, Case IH and New Holland 4.5 L 4-cylinder FPT (Iveco) engines with mechanical injection, including the Case 445T/M3 and the F4GE9454, F4GE9484, F4CE9484 and F4CE9487. Machines include Case 440, 450 and 465 Series 3 skid steers and track loaders, the Case 580N backhoe, Case 586G and 588G rough-terrain forklifts, the New Holland L190 skid steer and the Case IH Farmall 105U. CNH numbers are 2856255 and 504254390. It takes four per engine.

Mechanical injectors are replaced for hard starting, smoke, knocking, misfire or low power, and when a pop test shows low or uneven opening pressure or a dripping nozzle. Catalog data puts its opening pressure at 260 to 272 bar. Replace all four as a set so they match. Common-rail versions of the Case and New Holland 4.5 L use a Bosch common-rail injector instead, so confirm your fuel system first.

• FPT (Iveco) F4GE9454, F4GE9484, F4CE9484 and F4CE9487 4.5 L engines with mechanical injection (build dependent)

Clean the injector bore and seat before install, and fit a new sealing washer (chamber gasket), new return (leak-off) gaskets and a new dust seal. Tighten the hold-down and the lines to the CNH spec for your engine, then bleed air from the lines before cranking. If an injector failed from water or dirt, check the other injectors and the injection pump too.
