nice cluster view. remove rear gear first and its snap rings, rear gear is off now, so with wood block ,and soft rubber hammer (snapring off ) , i hit the left bearing, and the cluster slides to the rear with its bearing, the rear gear slides past old bearing bore hole (magic) and now i can use a puller to pull the rear gear. the cluster is free to pull now. tricky huh? same deal for reversal, but i used a pipe (close fit) to press the right bearing back on. same with rear gear and its bearing, use rubber mallets, only, and never hit steel to steel ever. at the most brass drift pins,... in rare cases. I had to center the cluster so all snap rings fit on both ends, that part was tricky.
