I must have missed something, the pulley does not have enough clearance to the main drive pulley, can't take bolt out,no clearance for removal. There is a spacer under it to keep it at correct height. I will ck when I get back to shop,to verify pulley above is not repositionable to allow bolt to be pulled from axle housing completely.
Finally got the belt on the 3pulleys on the left side of undercarriage, now, doesn't seem like quite enough slack to make it over the pulley on right. The tensioner is. At full slack. Cannot seem to get on any JD info pages for main drive belt diagram. I'm so over working on all my mowers, plan to get a brand new one, sell all my old stuff if can get them working to b worth something.
I guess I finally figured out why I had so much difficulty with this- somebody had this thing far enough apart, to install the idler bolt from the top down, there's no way to get it out,as the bolt cannot go up enough to remove,there's only about a half inch clearance on the top side. When I loosened the transaxle, all the affected pulleys are on the same mounting, no movement from idler to gain more space - fought hard to finally weasel the belt in between idler and upper pulleys. Now I've got it almost assembled,other than pulley on the right. Sure do appreciate all the info,and pdf.
Now you see why I flip that bolt over
