I have been working on a Stihl ms 360 that I got from my brother's landscaping company. It had a nasty piston and cylinderView attachment 204475View attachment 204476View attachment 204477 so I ordered one on ebay and put it on, along with some other items and then I installed it and ran it a little to break it in. It seemed to have a hard time coming up off of idle, so I took it apart again to check the squish (looks like 20 thou) and make sure I had everything together right and saw a crack in the crankshaft.View attachment 204474 It looks like they heated up the connecting rod bearings and the rod too judging by the blue discoloration. I believe that it was there when I got the saw and I overlooked it I suppose that I will have to take it out and replace it too. And the bearings and seals. I had so hoped that it would be a good saw after the P/C but that is the way it goes sometimes. Does anyone know somewhere I can get a crank for it? I looked on some of the sponsors websites and didnt see anything.
