I've struggled with this for a couple hours, trying several different things, with no luck. Time to ask for experienced help.
My SM420 is completely torn down, except for the reverse idler shaft, which I cannot seem to get out. The Novak directions say to drive in the retaining pin, after which the shaft can be driven out from front to rear, using a brass drift. I'm confident I have the retaining pin completely inside the shaft, but I can't get the shaft to budge. I'm about to use my press, but don't I want to break anything. Anyone else have the same problem? How did you get yours out?
