On the older 521 units, is the bolt that holds the pulleys on the crankshaft just a standard bolt with blue loctite? The drawings call it a "special screw", but it appears to be a 7/16-20 bolt (I need to confirm pitch). I have cleaned the old loctite off the screw threads with a dremel wheel, but before I chase the threads on the crank I wanted to be sure.
