Product review (1 stars): Buyer beware, parts to attach are not included
Buyer beware, this item does not come with the o-ring washer or the clip to attach it to the bracket.  You need to purchase the entire Idler bracket, not just the roller wheel....description does not tell you that.  It's ridiculous that it doesn't come with the parts to attach it since it is likely that if you are replacing just the roller, you would need these new parts as well....I wasted my money on this piece....
