Hey everyone. I have a 1997 Big Boss 400L with many many hours on it. It seems the first drive chain has loosened some and I need to tighten it up a little. Can someone please advise me on how to do so.

Thanks.

 

Check center drive chain first,if its loose loosen center adjuster bolts,ecentric turns to rear to tighten center chain,after tightening 5/8" bolts then check front chain,if needs adjustment ,loosen front 5/8' nut under front ecentric under machine there is an opening,then can use a dull punch to slightly tap ecentric towards rear to tighten front chain. Any time the center is adjusted,the front chain will be affected also and usually needs adjusting.
