This was a ported saw that was used for milling and got very very hot
it pulled over but only had 110 psi, things looked fine through the exhaust port so I pulled the cylinder (which is pristine)
The exhaust side of the piston was missing a sliver from the skirt.
The piston wouldn't move on the rod like it was welded on which is nuts because I could pull the saw over so it had to most at least some.
Intake side of piston scored but not terrible.
I popped the circlips and used my knurled handled pin punch to push the piston pin out except it didn't budge, at all, so I flipped the saw on its side and really pushed, nada, nothing
so I flipped it over and tried to push the other direction, no dice the pin didn't budge
I got my baby persuader from the saw drawer and tapped the end of the punch to jostle the pin (I have had to do this before and usually one tap frees it up).
Well you see the result, I was holding the punch and piston in one hand and didn't realize the crank had broken until I went to reposition the punch and realized the piston wasn't still attached.
Looks like a crisp clean break.
The seller told me ahead of time the saw was roasted while he was milling with it, so I aint mad and after seeing the piston skirt missing a piece the case was going to get split and cleaned anyway.
When I am done it will be a nice clean all OEM saw at a very fair price.
I originally planned to sell it but saws have a way of going Hotel California in my garage, so who knows.
