Card Reader Motor Dampener Repair

[klacombe]

I've read many of the posted repair guides and watched Geoff's video from the 2013 HHC conference but I've never seen a rundown of the size of the two wire insulations needed to make the dampener repair. I have made the o-ring repairs successfully and all but one of the readers have solid dampeners (seem solid and run very quiet). Just one of the readers has a definitely dead motor dampener so I'd like to try that fix as well. Just wondering what gauge wires I need for the insulation harvest. Thanks in advance. -Kevin
