Mark,
I have dismantled a number of engines that have had this type of shim placed in them - personally I always remove them and re-white metal the rod or line bore to suit having had the crank re-ground. I presume that they are used when caps have been filed or the rod is being fitted to a larger journal.
I always replace the big end bolts with new and use nylocks instead of split pins.
I always replace the little end bolts with new and use a spring washer and Loctite in preference of the tab washer.
If any of these bits let go it can get expensive very quickly.
