I have had this happen a few different times, but it was in saws that were up in the 210ish range of compression and happened after about six months of use, luckily they were my saws.
The un-torqued bolt could've easily caused the initial fracture to develop. I've been trying to remove a flywheel off a chink saw but I couldn't make it budge, I was fearing a similar outcome (or a bent rod) if I kept going on using the rope in the cylinder, I think I need to get an impact wrench for my air compressor... thoughts?
Not all OEM cylinders are Mahle. If it is mahle, it will say that in clean text on it.....
I bought a little 3/8" drive pneumatic impact for that job only and it works great! ebay $35. You still have to be smarter than what you're working with, though! :hmm3grin2orange:

And all this time I thought they used Chop Suey Mfg! Silly me.
But I don't think too many domestic (US) 361's had anything but these. I know 440's and 460's sported Gilardoni for a time, but I haven't seen anything indicating that the 361's did. 'Course I have been wrong before.....too. :wink:
And here's another shot of the discoloration along the one area -- which was also where the one bolt was loose.
I would try asking for assistance on the website, and see how far you get. It may be more hassle than it is worth on a customer saw, but you never know. You will certainly have to take the jug to s dealer for a look. Do you have one you are friendly with?
The loose bolt was likely the cause,why would they warranty that?Sort of like getting a warranty from the rim manufacturer after your wheel came loose on your truck isn't it?

I would try to get warranty for that if it came into my shop. Stihl will often call warranty stuff back to the factory and check it over for future product improvement. They may be interested enough to buy a new cylinder.
How did you determine that the bolt was likely the cause?
I think in both cases its a "QUALITY" ISSUE. Stihl i would think they would not want it to get around they make sh*tty saws don't back what they make workmanship and material even when it is out of warranty and is beyond what you would find without tearing the saw apart.
What a post.....don't you realize that Mahle is one of the best oem suppliers to most saw mfgs, not just Stihl but Husly and Dolmar as well, one of the top automotive suppliers as well for performance pistons. If there was a casting flaw, no fault of Stihl's, like wise if it were off another brand. If a guy came into our shop with it, we would try to get him helped. Just like the numb nuts who took a impact to a blower last week to tighten the shredder blade with a screwdriver wedged against the piston. Bent the **** out of a forged rod. Unit was under warranty, we did get it covered. We try to fix stupid one time, then their on their own.

No guarantee of course but it stands to reason.The cylinder has a three corner torque on it with the fourth loose.An uneven clamping force at best,or the beginning of a stress riser at worst.It's hard to imagine that not being the cause,given the look of the cylinder.
