Clamp the new piece in place with a generous amount of Loctite and drill 4, 1/8 holes evenly spaced across the piece. Take a short piece of 1/8 brass welding rod, coat the tip with Loctite and drive it in one of the holes till it bottoms. Do the other 3 the same way. Take the clamp off.
Using a fine tooth jewlers saw cut the excess brass off of the pins. Now peen what is left down till it is flush.
Face and bevel the insert to finish size.

NO, you can't shim a bearing shell and expect it to live.

Thanks for that description Pete.


The shims I read about here were behind the thrust surfaces only, much like the inserts you describe. So you say that does not work? Is it because of lack of heat transfer?
