The tool is pretty universal, no matter what brand of starter or generator is being repaired. There's supposed to be a threaded expandable strut that's placed inside the housing to prevent collapsing or distorting it when pressure is exerted on the jackscrew to keep the tool in the slot while removing or installing the pole shoe screws. I started using that kind of tooling in the late 1950's in my father's shop.
