Ok so I went to put the belt back on today and it looks too me like there isn't a tensioner pulley....as in it came off.....I don't know if that's even possible but what is there looks like there should be more to it.... The belt "overhangs" the "pulley" which is greasy....to me it looks like there should be more there....Am I wrong?? And if I'm not, where can I find a replacement?? Couldn't get pics to load I will try again later if needed....
