Tensioner screw which adjusts chain tension was bent.

Tools Used
Screwdriver, Adjustable Wrench
I removed the outer enclosure and chain/bar which allowed access to the tensioner and screw. I just unscrewed the old bent screw and put the new one in its place. There was a small clip that fit over end of the tensioner screw which keeps the screw from sliding out of its track. It is very easy to miss this clip which I almost did and it is a necessary part to make the tensioner screw work properly.
