MS260- Can it be saved

[Fatboy2017]

Another alternative you could try (nothing to lose) is, if I'm not mistaken, the area behind the pin boss is behind the exhaust, you could drill it through, clean up / level  the area where it has sheared off,  use a stud with a small shoulder, with a thread on one end, drill out the centre of the other end of the stud with clearance to take the pin, there is not much load on it, the original area must have had too much clearance on the pin , so loose, causing it to move back and forth ending in failure, cost very little if you do it yourself and if it doesn't work then you fit new case.

Yes I was thinking rivnut but not having seen a 260 for several years I can't remember what goes on there.

 

PS I wouldn't consider splitting and rebuilding a saw that old, especially seeing the chafing wear on that spring, too many other parts to consider

I didn't like to suggest a Heath Robinson repair on a primary safety device but the dowel does go through to the muffler side so a threaded rod...yada yada yada may work but you don't want the bugger to fail with the bar heading for your head at 60mph

If you tackle the case replacement, you can say you are a man when the thing is running and working fine.

8 months ago, I would have sent you a crankcase for the postage but they are long gone.
