Danky, have you looked at wave hogs pump install thread, had some close up shots of the shoe area work, also JD aka specialfx might be able to chime in, make sure your 6304 bearing that was pressed into the yami housing is straight and that the mid shaft housing is flush on the bulkhead wall. It may have a gap or the bulkhead may be slightly out if true and buckled. You need to get the shaft straight first so the pump can follow suit.
