What is your tried and testing method for installing the case crank bearings? I have a motor project I am working on and want to try to do the install myself.

Side question: I have a crank where the (2) crank bearing fit by hand on the crank. Isn't the stator side crank journal a tight slip fit into the bearing?   

Another thing I like to do is when pressing bearings onto a crank is to put something between the webs of the crank opposite the rod pin to support it.

I was told to put all the bearings in the freezer for 24 hours and heat the case halves up in an electric oven. the bearings should drop right in.

Well I did it -

Put the bearings in the freezer for awhile. I used a torch (saw it in a youtube video) and heated the case up. One side slide right in with no additional force. The other side took some beating but it went in.

Now I need a crank. The one I have, the stator side slides right in - its not a slip fit anymore. This allows too much side to side play when the crank is in the case.
