    Default 7030 allis chalmer injectors

    hello i am trying to pull out injectors out of my 7030 allis chalmer and they just dont want to come out. i tried a slide hammer and dint budge them so tried a pry bar nothing, than last night i tried a shop crane and got 1 to pop out no damage done to it but it took so much preasure from the crane to pull them out. is there an easier way to pull them out. thanks

    When they become stuck that tight, you may have to make some sacrifices. Remove the exhaust manifold(if you haven't already), and unscrew the pressure adjusting screw from one injector. Weld a nut to it that will match the biggest slide hammer you can find. Remove the spring from the injector and thread your new "adapter" back into the body. With some help from a large heel bar under one of the flanges and a strong arm to pull on it, give your slide hammer all you've got and see if it moves. You might also try a big punch to try and rotate them to break the rust bond before attempting removal. Sometimes by the time you get them all out, there's not much left of them.
