Thanks guys, one question though:
Can the nylon insert be removed? Could it just be pried out with a small screwdriver? I would only need to remove it in case I need to adjust the nut after I put the transmission back into the machine. It didn't need adjusting before but I don't know if it will when I put it back in. I think there needs to be 1/16" inch clearance between the clutch plate and the basket drive pulley, so I think adjusting this nut would do that. This is my first rebuild of a gearcase & basket drive so that is why I ask. The picture I posted is before I did the rebuild.
Thanks!!
