I got tired of working on my 33 so thought I would rebuild one of my extra R-9s. This on is in bad shape and I will have to replace 1st and 2nd gear on the out put shaft. My question is has anyone removed the pressed on lock and found a way to replace it. I have several sets of extra gears from none OD transmissions. Thanks for any ideas. Dell

Check with Ron Carpenter in Walnut Creek. Last time I was at a PI Membership meet he indicated that there may be someone in Norcal that was re-assembling the mainshafts.

It's easy enough to take them apart as the retaining ring for the gears is relatively soft and can be cut with a cold chisel.

Re-assembly is a different story as the retaining ring must have been originally crimped in place with a heavy press so that it not only served to retain the gears on the shaft but provided a preload for the ball bearings.

I would be very interested in finding a solution as well since I have a collection of bare R9 and R11 mainshafts, loose gears that are good and other shafts with good gears.
