Today, out of nowhere, my '51 started popping out of 3rd. On a 3 speed, this means a lot of slow driving unless I hold it in gear. I switched motors over the winter and had the tranny out. New throw bearing, fork looked good, clutch is all good. Drove it without problems until today. Trying to figure it out, I noticed it doesn't "click" into 3rd like the other gears. I don't think its anything wearing out since there was no warning at all. Linkage was never touched in the swap.
Any help?
