Hi Folks...
I have a Timber Bear that I had an issue with last time I went wood cutting. I was felling a tree, so saw was 90 deg with the drive sprocket upwards. The chain apparently rain into the cylinder plate/jacket and tore it up and got jammed/ripped up. I was out in the forest and didn't want to come home empty handed, so I ripped the rest of the metal off and got by for the rest of the day though the chain hit at least one other time. (and later that day once home learned how to actually get the sprocket off)
Question: What could have caused this issue? Why would the chain hit the cylinder plate/jacket AND dig into it? I figured, okay, maybe a loose chain is the main culprit, but wouldn't the jacket deflect the chain (its purpose)? Any thoughts? Some pics...
Thanks!
