here is the second main cap from the rear and I have "R" on the cap towards the rear main cap and not towards the front two main caps.http://i1291.photobucket.com/albums/b554/stovebolt56/2013-05-07_20-01-43_129_zps49b6b49c.jpg

What are these 2 dimples on each side of this bearing? This bearing I have the second one from the front and the "F" is towards the front main cap. http://i1291.photobucket.com/albums/b554/stovebolt56/2013-05-07_20-03-37_758_zps1c295aa0.jpg

When I took this motor apart it did not have any shims.
