Idler Pulley for my Craftsman Lawn Tractor
The pulley, belt and hex bolt I ordered were exactly right. Although we had a little bit of a hiccup on delivery, (I'm blaming it on the P.O.!) As soon as my parts were back in stock, my order was back on the road again. In the interim, they kept me up-dated as to the progress of my order. I appreciate you guys!

Removed the mower deck from the machine. Problem had to be caused by something other than the belt. Visual inspection of pulleys revealed one had missing bearings and sat lopsided on the pulley shaft. Ordered second flat pulley just in case. Reinstalled pulleys, deck and new belt. Mower worked fine. Followed deck removal procedure in owners manual.

Removed the drive belt and then removed the two pulleys that were bad. Replaced the pulleys and the drive belt. Just remember which pulley goes where since they are different. Access to one of the bolts was a bit difficult as well as being under the raised mower was not ideal. Otherwise it was a relatively simple replacement. Far better than paying a mechanic $75 an hour to do the same thing.
