This is how the 3 shims were expained to me. When you use 2 flat surfaces
(like our shims) one surface is achored while the other moves. Wear becomes an
issue. But if you use 3 surfaces (shims) then you can move 2 surfaces together
while the 3rd stays put (or rides with them), and wear is diminshed. Torrington
created this style of bearing long ago, that has essentually 3 moving parts,
granted their middle piece has ribs (for lack of a better word). If you think
about it in a VW engine, you've got 2 stationary sides (the #1 bearing, and
the flywheel), and a moving side (the 3rd shim). The bearing gets a little wear
(it's soft), but the flywheel really doesn't. The 3rd shim acts as a bearing
(it does get oil) between the other 2 shims. I don't know if this helped or
not, but GM, Ford and all the other auto manufacturers use this type of set up in
their AT torque converters.
