Can someone tell me the stihl part numbers for the piston stops that fit the cmr6h plug hole and the bpmr6a plug hole. I tried searching the forums but came up empty.
A rope is better yet, won’t ever put a hole in the piston.Those Stihl piston stops are terrible, their weak plastic rubbish. The aluminium screw in type stops are much better.

Flywheels?I work on saws almost daily, have never used a piston stop. What's the need?
Clutch comes off and goes back on fine with impact gun or a sharp tap with a brass drift and hammer.
Flywheels?
How do u torque nut without a stop?
No thank you. Not accurate enough. For a clutch i agree, as it is self tightening.Impact gun.

For a flywheel, esp for the newer cast in key types, thats a recipe for a sheared key.
This kinda experience is why I don’t use impacts on crankshafts.Holy ****. I kinda screwd up and took crank off on fly wheel side with my impact. On tear down i found this.

Okay ill say it brad was right. Ill be looking into meteor 064 pop up now instead of the golf.
This saws barrely ran. It was a ticking time bomb mabe it cracked because i messaged it with a carbide burr maybe it cracked because its a golf piston.
I will salvage the carbar rings.
Im currently splitting cases. I have to replace the crank and i guess get another set of seals unless i feel these ones survive tge tear down heck maybe ill just run a 046 piston. But man i really wanted to do the 064 pop up. Or maybe a 272.
Crank, bearings, piston and give it another go
I agree, but it’s also from an impact. Takes a little more effort to break it off while hand tightening, too easy to do with an impact. I’m sure that over time, you can get a feel for the torque required for tightening and loosening with the impact, it’s also easy to ruin a project by being in a hurry.That's from a piston stop.
