Front Drum Inspection and Removal (part 1)

I bit the bullet and started on the front drum.

The right side came off without too much problem using my air impact.

The flex mount to the right is bonded to the plat and the bushing it its center.    From what I can see the mount on the other side has let loose of the plate.

The other side did not go nearly so well. The photo to the left shows the bolt I ground down because the head was stripped.

I do not understand how this pulley is supposed to come off.

I have removed 3 bolts from the face.  There is a hole on the top that could well be for a set screw but so far repeated cleaning with pbBlaster has not revealed anything that an allen will go into.     It turns out that the pulley on this machine is the style used on post 72 machines shown here.  The diagram is rather poor.  It does not show the 3 bolts I removed from the face although it does show that slot in the bushing opposite the keyway.

The slot in the bushing tells me that if collapes a bit when forced into the pulley to make a tight.  If that is the case a few blows with a chisel between the hub and pulley should knock it loose but it did not.  There must be an allen screw locking it down from the top in the picture above.
