I rebuilt the mower deck on my Craftsman GT3000 tractor last spring. After grinding off the rust, epoxying the underside and painting it, I replaced several pulleys, belts, and one of the bearing/blade holder assemblies. Yesterday while mowing, I heard a loud squeal followed by smoke and burning rubber. Pulled it into the garage, and this AM I pulled the deck. The drive belt for the deck was twisted and frayed.
The cause was separation of the top and bottom halves of one of the new replacement pulleys. (See Picture). I bought all of my parts from eBay, since Sears is pretty much gone and has only a few parts available for shipping sometime in this century. Despite paying a bit more for "OEM" parts I have to wonder if the parts I bought really are OEM. After all, the original pulleys and belts on this tractor only lasted 20 odd years. (When I rebuilt the deck, one of the pulleys (not this one) had similarly failed, but it did not eat the belt.)
Is this a common problem? Can I expect a new pulley to also bite the dust in a matter of months? I mow about 3/4 acre every other week during the growing season. The tractor usually logs fewer than 50 hours a year - probably a lot closer to 20 or 30. Note that in the picture I've not started loosening the retaining nut. What you see is what I saw when I yanked the deck.
