I would like to satisfy my curiosity as to how engine bearings are installed into the crankcase in commercial practice. That is, how is it done in the Nelson or Fox factory?
I have changed bearings in some of my engines and have always heated the cases to expand them, but the way I do it takes me ages to get right, and I am never confident that I have got the heat right. It seems to me that it would be more of a problem if I was doing a hundred or so at a time. Do the factories heat the cases, or somehow assemble them cold?
If heating, what actual temperature is the case raised to?
Thanks in advance
Charlie
