I bought three loops of 114 dl x .063 x 3/8 ripping chain for use on my 36" stihl duromatic bar and 8t sprocket. this bar takes 114 or 104 DL of 3/8 or. 404 chain, respectively.
I decided I wanted to go to a sprocket nose bar. My stihl dealer ordered the 36" sprocket nose bar for the big mount Stihl and swapped out the sprocket with a 3/8 sprocket. one stihl tech said it should work with my chain, but another never got back to my dealer.
the bad news is that when it came , we saw that it took 108 DL of. 404 chain with a 7t sprocket. my chains will not even fit around the bar, let alone on the drive sprocket.
I am thinking about having my dealer take some links from one of my chains and adding them to the other two. Can I just divide 114/104 (the ratio of drive links for my hard nose bar) and then multiply this by 108 (.404 DL required for my new bar) to get the number of 3/8 DL needed for the new bar? do I need to account for the difference in sprocket sizes (new bar specifies 7t but I'm running 8t)?
thanks! terry
