Install The Bearings On The Shaft

Install The Bearings On The Shaft

This task is perhaps the most difficult of the entire process. The bearings need to be pressed onto the shaft and it's a very tight fit.


I used an old trick I taught to me years ago for doing just this sort of thing. I simply heated the bearings, in the toaster over (my wife doesn't know I cook bearings..), to 200F. At the same time I had the shaft in the freezer.
