Finally got the proper bearings for my build 17mm I.D, the axle is 17mm, in trying to install the axle the bearings are very tight, won't go.I was wondering how much persuasion is ok.I have not tried tapping them on yet as I am being very cautious with this project.The bearings are getting stuck on the axle within the first 1/2".Any thoughts/help appreciated. This is a Staton crank shaft kit btw.
