Hey thanks for all your info man. Question on this. I want to tear the whole motor down so I can bring it in to get hot tanked. The amount of sludge I saw makes me really want to do this, also I want to get a good coat of paint on her too. So, your logic about the bearings makes sense, but I am wondering if I can tear it down, inspect the bearings, and if they look good, reuse the bearings? And so the same with the rings. It would save me probably $200 give or take, and every penny counts on this build. But not sure if its worth it..
