Chainsaw Repair

Someone must have ham handed the decomp in and it c-racked the top of the boss off the cylinder.





Build up weld.



Drilled and taped new hole on the mill and then finished off the rest by hand. The hole was a little off originally from the remainder of the original. I had to move it over so the decomp would seat correctly, so the threads are not full circle but it's plenty to hold it tight.





After a little blending with the bead blaster. (Sorry for the sideways picture, photobucket takes forever to update an edited picture.)

Very nice. I had a 084 cyl with bad decomp hole that could have used that treatment.

Hmm, so this is a common failure?

Mine was the first I had seen. But Lakeside Andy seemed to say it was pretty common when I ask him about it.  He had pretty much said to fix the same way you did.

Not sure but thinking Ron may have my old cylinder. The threads were gone on half a side if I remember right.  @man of stihl

Yep I still have that cylinder.
Nice looking fix srcarr

Good looking work. I think I know who's cylinder that is.

No problem.
