Trying to change the axle oil seal on a Craftsman 20 hp 6 speed (manual) Garden tractor (Model 917.273030) Pulled the wheel off and the C-Clip. The axle shaft is approx. 1" out past the face of the Hub. The C-clip is not against the Hub facing and I can't figure out what holds the Hub from sliding off the axle. Both are spline groved. I don't see a key or pin that holds the Hub sleeve to the axle spline. I'm I blind or what am I missing.

Hi, easy fix you have to pry the cover off. you can use a screw driver, or a pry bar.

check two things, make sure the by-pass rod is pushed all the way in and the drive belt from the engine to the rear end (tranaxle). If both check out ok do not attempt to service the tranaxle at home. have thet serviced by a dealer.

Wayne Train Hi Bobbyak, if you still need to know, there is no key. It is a D shaped shaft, the pulley has the D cutout built in. It is a tight fit to pull off, but it will come off with some wiggling effort. There is just enough room. Remove the belt. Mark the side facing the trans for when you refit. Don't give up and don't drop the transaxle. I just didn't catch the reason you wanted to remove the pulley.
