In the past I removed o ring , spacer & shift rod. Next I clean all mating surfaces, then lube the o ring & shift shaft & with inert lube &install shift shaft in the upper case then slide the o ring down the shift shaft until seated in the case. slide the retainer bushing down & tap into place. This way I can adjust the o ring tension with shift rod in place.

I am going to try your method next time I do a shift shaft O ring. What did you use for an inert lube? Another post said after he installed O ring he pumped some grease into the retainer/O ring cavity and I thought that was a good idea too.
