I am trying to put together a engine with all new parts that I got at an auction. Where can I get connecting rod spacer shims???? I understand they need to be installed to have the correct rod bearing tolerance. Thanks

David, see my response to a post on page 2 of this forum re a 39 B crank. You really need a genuine AC Repair Manual. Without it you are almost sure to ruin this rebuild job. It will have the complete detail of the procecures to use the shims correctly and to fit the insert to avoid ruining the crank. It is not too difficult but you need to follow closely step by step. Good luck.

MY BOOK STATES THAT THERE ARE 4 SHIMS ON EACH SIDE AND THAT THEY ARE .0025", AND THAT YOU SHOULD ONLY REMOVE ONE AT A TIME AND NO MORE THAN 2 FROM EACH SIDE. LOL BOB

or you can cut your own from stainless steel shim stock. buy at NAPA., etc. Originally there were 3 shims .002 thick on each side of the cap. This made .002 clearance between the bearing and journal. As the bearing or journal wear you removed a couple shims. If your parts are all new, you need shims, if they are worn a few thousands, you may need only 1 shim. I made mine from stainless stock. as the guys said, as you take out shims, you need to file a few thousands off the end of the bearing insert so it does not get crushed hard and bind on the journal.

You need to know what you are doing to shim a bearing. If the clearence is too much you need to reduce the bearing shell by fileing. When you file you then need to reduce the shim thinkness, always maintaining the proper amount of bearing shell "crush". Look back in the archives, if you don't find it you can e mail me and I will describe the procedure. The above description is not all you need to know.
