Check the center main bearing !! especially between the #2 and #3 arms. That's where they wear !!

Thanks, Dr A - I was not going to check the main until I saw your post. It is also .002 like the first rod cap - I assume that is also within specks and not in need of replacement? Miller

Mains are .0014- .0035 so your good. I did a engine in a red tractor that was just one main was bad. I wasn't going to check all the bearings but at the last minute decided to. Good thing because I saved the customer some big money
