Remove four nuts from bearing cap "A" and remove caps and shims.
Care should be taken to screw the53 bearing cap onto the shims as tightly as possible each time the blueing test is to be made.
These shims provide the method of taking up the wear in the babbitt that will eventually result.
Then replace bearings, shims and caps, draw up wheel hub tight on shaft and install cotter pin.
As to the front half of the box, no shims are required, since the tapering key brings that box up to its proper place.
When we received the weapon yesterday, there were shims mounted in the rifle.
Would you recognize these shims that I display to you, Mr. Simmons, as being the shims that were placed in the weapon?
