So I recently picked up a pair of 62t cases from member here, and they were shipped with the steel hardware unrestrained and trapped inside the cases. When they arrived I found a few dings in the bearing surfaces where the steel hardware had hit and deformed the aluminum. These cases will eventually be going into a TPE engine with a small 4mm stroke, and I just want to make sure that these machined surfaces don't need to be perfectly flat to avoid early engine failure.
I'm not so concerned about the recesses, but rather where the dings are, there is a small amount of material on both sides of the recesses that are otherwise protruding past the intended machined surface.
Take a look at the damage, and let me know if first you would have any concern, and second if I should just try to sand or grind them as smooth as possible. Or if this won't be a problem at all, and the aluminum will flatten under the steel bearings once torqued down on the cases.
This last one I think I will just hit with a flat grinding stone. I think it was from a forceful dis-assembly.
