Thunderbolt Distributor Rotor - Stuck!
 

I was changing the plugs, wires, rotor and cap yesterday. Just some overdue maintenance. All was going well until I got to the rotor! The thing was stuck on there and would not budge. I pulled with my fingers and pliers. I pried with assorted tools not designed for the task.

A friend finally helped me out by having a dremil tool handy. It still took a great deal of prying / pulling. The rotor appeared slightly rusted / glued in place!

First -
Is there any easy way to pull these off? Has anyone developed a puller? Should I just plan on cutting them all off?

Second -
Why was it glued? Should I glue the replacement? What should I use? It seems like it is on there pretty good without any adhesive. (maybe I should have greased it?)

All input is appreciated. I have two more of these to do.

Thanks!
