Ha! Just after doing mine 2 days ago! Took out the old ball races to find that only the lower one was standard size available in a bearing shop so had to put back in the old upper bearing while I look for the right size roller for it.dazz245 said:
Anyway the bearings you need are: 30x55x17 lower and 26x47x15 upper. Your just looking for normal tapered roller bearings in that size. The 26x47 bearing is an awkward size and seems to be only used for bike headstocks. I ended up finding one on ebay. Good luck with it.[hr]
Oh yeah I presume these are for the mc22?
