I just looked at a couple rotors and see a small roll pin pressed inside a larger one.
The ID of the smaller one is .08. This would be a very small self tapping screw to use
with a slide hammer. Has anyone been able to do it this way? As for pressing it out;
the gear is larger than the rotor bearing; no way to get a mandrel in there. A puller
would have to have a claw thickness of < .06 to grip the backside of the gear. Has anyone
done it this way?

Nobody ever takes the gears out.

I have a rotor here that has all double drift pins.

Two other possibilities.

A)
Block the rotor up on a bench with the gear on the bottom so the gear has room
to drop out. Use a 1/8 diameter drift pin.
Go in from the top and tap tap tap the gear out from the top side. I think all pockets go
all the way through to the phasing gear. You can feel the edge of the drift pin
contact the phasing gear. If you look closely from the right angle on the gear side
you can also see the tip of the drift pin behind the gear.

B) use a large screw driver stuck in the .060 gap to pry the gear up all around
so you can get a puller in there.

Perhaps a little heat on the rotor would also help.

When you get the gear out please take a picture of that side of the rotor
without the gear.

Paul,
I have half a rotor so the pins are easy to get to as you can see them. I
can just punch out the pins, is an old 9 pin photo good enough and would you
like a bigger photo than what I have been sending, I notice they are pretty
small.

Bigger is OK with me. I can scale photos no problem. You can send photos up
to 5 meg and I will scale them down. 5 meg appears to be the limit for email.
