Depends if you want to keep the saw and use it for "learning on the job". If you're looking to make money, OTH, parting it out would likely work out better. Sure sounds like something wrong with the bottom end, so the case gets split, etc. If the conrod bearing is bad, an OEM crank is expensive and AM has its risks. Hopefully you'll be able to borrow tools from the shop, including the pressure/vacuum test setup & seal press. I'm going through a similar process with a blown ms460; the whole thing had to come apart and the local shop loaned some tools plus will install the crank bearing seals and perform the pressure/vac test. No guaranties for me, though, and the whole thing may end up a bust. Guess it depends on how curious you are.... Now I have a lot of work to find and repair the damage. I'm starting part-time at a saw shop so that will be helpful. Or maybe I should just part it out and not stick any more into it?
He called your momma a VolkswagenGreat poast!
Jim, I think you got it. That piston damage is identical to mine. Now I have a lot of work to find and repair the damage. I'm starting part-time at a saw shop so that will be helpful.

That's good news. Keep tearing it down. Hopefully you'll find a broken cage on one of the main bearings and the search for the failure can end. Is the cylinder salvageable?...I inspected the rod bearing closely, turning it with a pin. I saw no damage or marks on the cage either side of the rod. Rollers looked clean and turned smoothly.
I thought the same thing but it seems to be by design.Oh, and in the last picture of the first post.. it looks to me like the cylinder skirt is broken? Is that an illusion?
Good luck with it
I looked for scrubbing even on the softer plastic of the crank stuffers. Nothing of the sort, everything is smooth and clean. No debris in the bottom of the crankcase either. Whatever it was it went through in a hurry and the only damage it inflicted was on the piston. I'll look at the main bearings later this week.Do you see any scrub marks on the casing around the crank? signs that something got dragged around a few times? Might be pretty hard to see around it with things assembled I guess though, it is a full circle crank which doesn't leave much room for inspection
