'Gummy wheel'


I am looking for a 'Gummy' Wheel repair for an HP 41 card reader.Can anyone help me?

Kind Regards


Look in the 'Articles' section on this website to find instructions on how to do it. It's actually not difficult if you follow the instructions carefully. Most important is not to lose any of the small parts and not to bend the switch contacts, most difficult (for me) was finding a suitable replacement.

Cheers, Victor


Gummy wheels including repairing instructions are also offered on eBay. See item nr 3054833188. BTW, waterhosko is a very nice guy, a pleasure to deal with.
