Don't want to strip motor down completely yet until I get more info from William Wynne but had to do something. Removed bell housing and hot tanked to clean, still needed some scrubing in parts washer after that. Did some ruff cuts on it so it would fit in my band saw at home better. It has two studs on inside I ground down the head of a bolt to make a third stud so it would sit square on the band saw table for cutting.
