HP-65 more on the card reader

[Geoff Quickfall]

The red insulator fits inside the white insulator. The motor spindle is thinner then the worm gear spindle.

Therefore the red insulator slips over the motor spindle and the white insulator fits over the worm gear. The new dampening assembly fits inside the aluminum tube. The red insulator section fits inside the white insulator and only takes up half the length of the white insulator.
