extracted this guy from beneath the center of the LT1000...idler pulley for engine drive belt. Needed 3 hands for this operation so took a while with two. To install new one had to glue the nut into a box wrench so I could hold it in place and push bolt with pulley on it up from underneath and get it threaded on the nut. Not really anything easy to take out to give better access. Anyway it's done and all is working OK again. This is what happens when the bearing seizes and you don't know about for a few months...
