Hi Larry!

Werner,
Larry hasn't replied yet, by my posts, but I
couldn't help but say with
GREAT DIFFICULTY, unless he has a system and I guess the
bigger they are,
the easy they are to tap and get a screw into them for
pulling.

   I for another would like to know how this roll pin is pulled. I seriously
doubt that the spring steel pin could be tapped. It's probably as hard as the tap.

You pull the gear or press it out from the other side. It is just held in with
friction. Some of the roll pins may come out with the gear.

That leaves a part of the  roll pin sticking out. Grab them with vise grips. If that
does not work you have room to tack weld on a short pcs. of welding rod and use that
to pull them out.
