Re: 200-4R Rebuild ... step by step!
You leave off the center sealing ring in the direct drum (actually on the drum), and the 2nd sealing ring on the center support, and then block the bolt that goes in the reverse passage by welding the hole up.
But you MUST use the billet forward drum, or the first time it WOTs from 2nd to 3rd, it will snap the shaft.
