You also have to remove the inner race off the tranny shaft where the drive pulley is. You can see it once the inner primary is off. It should have .100-.200 clearance to the edge off the main drive gear to get the puller on it. They have a habit of sliding back so there is no room for the puller. Gets tougher then. While it, the gears, are still in place take the top off and remove the shifter drum. Then slide a couple of gears around to lock the shafts together so you can pre-loosen the 2 nuts on the shafts. Makes it easier once you have the casset out of the case.
