When one gets the cluster gear out, it is helpful for reassembly to make up a dummy shaft for it to keep the roller bearings corraled. Get a piece of the correct diameter EMT or water pipe that fits inside with the bearings in place, just short of the cluster length- wise, insert the cluster w/ bearings greased w/ dummy shaft inside, when in place, push the dummy shaft out w/ the correct shaft.
