jd110 (Sq Fender model) need diagram of drive belt tractor to mower.

[farmer1]

hi I need diagram for the drive belt from tractor to mower. the mower is a 39 model. Also I replaced an idler pulley on the 39 deck . When I removed the old one it was attached only by a bolt so i replaced the same way-it seems to me that there should be a bushing on the bolt so the bearing fit would be snug? thank you j
