OK we'll see if this works......

There is a piece of steel bar that gets fed through the holes in the sides of the damper - long enough to fit across.
It has a hole in it that allows the hardened "pusher rod" - threaded bar - of a puller assembly to pass through.
It has a nut that fits the pusher bar, tack welded to the cross piece.
Tightening the pusher rod against the end of the crank (while protecting it from damage) will jack the dampener out and off the snout.
