I am new to Arctic Cats this year and have been very happy with my 1997 Cougar. It currently has over 10,200 miles, still runs strong. I logged 1150miles so far, but today 8 miles into a ride I set up with a bunch of lads, all with newer machines and I broke down:angry:. Turns out bolt #23 in Auto tensioner snapped apart. Nothing you can do about it on the trail! I think i will switch to manual tensioner. Question I have is how does the body of the auto tensioner get removed? does it thread into the chain case?
