 Statesville, NC | My 7000 has what appear to be single pitch sprockets, but requires double pitch chain. I tried single pitch chain on it and it would not wrap around the 14 tooth sprocket. The double pitch chain worked fine. I discovered the sprockets looked like single pitch, but were machined slightly different for double pitch chain. On the small sprocket, each link bends more, and the distance across two links bent at an angle is less than the distance across one double pitch link. | |
