Re: Con rod pin bushing
Burnishing pushes the bushing out to fit the surface of the inside of the hole- in the rod... I had the mandrel to do it, as an addendum to a Sunnen hone... I think that it helps hold the bushing in place, and helps the bushing hold its size...
You still have to press the bushing in, first
I don't think that I ever used it...
