Quoted from bdPinball:....
I'm not sure if the removing a stuck coil sleeve counts as a hack, or something "bad," I do it all the time! I agree with Bingo- if it's not broke, or on fire, don't replace it!

I'm currently working through a row of '60s Williams pins. Nearly every coil sleeve in the playfield is worn out and stuck. Cut 'em out with a saw if necessary. Replacing 10 or 12 coils per game simply will not happen.
