It's made well. There are no instructions included whatsoever. By referencing the pictures in the listing on Amazon I was able to ascertain which bolt out of the two attached to the roller wheel to the bracket. Upon doing this though and using the included washers as it appears they did in those pictures, the lock nut does not thread on far enough to grab the locking portion of the nut. You are unable to completely tighten the wheel to prevent it from moving up and down on the bracket. In addition, had they used a two-nut design, the position of the wheel could have been fixed without putting excessive pressure upon the bearing in an attempt to keep the wheel position fixed. As it is, tightening the wheel enough to keep it from moving up and down puts pressure on the bearing so that the roller wheel does not move freely.Including instructions for the various applications would have cleared up the ambiguity.

This tensioner is a great fit for Predator 212. It fits right on the available holes under your clutch. It's made of very thick steel and machined accurately.The slotted end barely clears the bolt on the engine, giving you the best chance of clearing your driven sprocket.If I had to pick a couple things that might be improved, the pulley itself feels a bit narrow. It's probably fine, but I chose to use a wider pulley from another kit. Also the length of the slot doesn't give you a whole lot of tension adjustment. I don't think it will take up tension from a whole added link.
