Re: Rear axle housing repair sleeves not hardened
The 1930 engine I pulled out of a Vermont farmer's back lot had a sort of mechanical internal spring added to each piston. It sort of "yoked" around the piston pin so they can't come loose. By removing the center lock pin, the expander could be compressed with a pair of vise-grips and withdrawn. They had a fair amount of spring to them - almost like wear your safety glasses and shield lest they squirm out of the vise-grips and hit you in the kisser.
I kept them but more as a conversation piece - I don't think I would use them.
