Yes,the chain goes on top of the lower roller,around the swingarm roller,and under the top roller.If the one roller is stuck,it's probley the bearing.Take the roller off and clean it up real good with WD40,if it won't free up you can buy a new roller with bearings for around $10.To loosen your chain brake free the lock nuts on the chain adjusters and back them off.Then loosen the top and bottom carrier nuts and thats that.I tighten my chain intill there is about a half inch movement on the top.I also know people that strap the garb bar down to the swingarm and tighten the chain up,and they say it's perfect once they loosen the strap.GOOD LUCK
