      The direct drive was one of the patents they got from deere... lost our books but seem you need to loosen the bolt (LH or RH thread ?)
      and move the axle to the right .. might need to loosen cog drivers and slide them enough to let you get the clutch out of the way..
      May need to punch the cages out of the brgs and drop out the balls if they are seized to the shaft..
      Deere used ordinary fafner brgs and flanges .... 7/8 " on LH and 1" on RH .. used same flange size...
      ...
      Next method ... cut big hole in side so you can pull the axle out the clutch side with the shaft after punching the brgs..

              Clutches are keyed in like a normal indy. Keep the penetrating oil on it, it will come. It is a different clutch. Very fragile. A clutch in good shape is almost worth more than a whole sled. Tracks are nla. If you have 2, I suggest running one and preserving the other for spare parts.
