My Crankshaft pulley is rust-bloomed and needs replacing, the amount of sanding to get it ok isn't worth the time. I have the replacement, but for the life of me cannot get my head around how to actually get the old pulley off. After reviewing the parts catalog, the Starting Dog (hand crank piece) and the large nut appear to be one piece. How is it threaded, reverse or regular?

I appreciate your help!
