Re: hopelessly stuck rings

Your 1st pic looks like casting flash Wedgie. On the second pic, I am trying to see the problem from the angle you take it. In my 40 years around the machine shop, I have learned that with aluminum casings with bearing fits; including cast steel casings with bearing fits; they all have to be preheated and kept warm during the welding process to stop warpage. I guy just showed me a Merc 20 bottom end done and now his bearings do not line up. A qualified welder would normally know this. And as you know Merc bottom end casings are much thinner than OMC’s
