HP 41 card reader repair question

I am repairing the hp card reader and have found the worm drive gear was slipping on the motor shaft. I removed the worm gear and cleaned out the aluminum tube. Now I need to know
--what can I use to back fill the tube with and
--how do I adhere the gear back onto the motor shaft ?

I have read the how to pages on the repair for this unit but need a little more help. I tried to use wire insulation to fill the tube but can't find anything that fits.

thanks for any help

I did manage to get it back together and it seems to be working again. I used the O rings method on the driven gear and I managed to get some wire insulation squeezed into the tube so the wormgear is working again.
