    When trying to diagnose a motor problem, 2 of the top bolts that hold the motor snapped due to corrosion. Tried searching but couldnt really come up with anything. Any way to get these bolts out? Insta act mm2 straight blade pump. Any help is appreciated. Thanks

    Very common. Welded some sacrificial nuts to them and out they came. Made sure the manifold had no orings in it when doing this. Took about 4 or so tries and it was good to go.

    Just watch. Those housings are aluminum....melt real good under alotta heat. My westerns did this. I dielectric greased the motor to pump base and greased the small hole that's in the motor. Also taped and greased the bolt holes as well

    Thats what I do. Usually the heat from welding really helps get them out.

    Finish taking the motor housing off. Also you must completly remove every component in the manifold
