New-to-me HP-65: card reader troubles

[0culus]

Hey all,

Longtime lover, collector, and USER of HP calculators. I added two in the last week...another HP-15C and a beautiful, complete HP-65. The 65 might as well be new...it has everything and apparently only one owner before me. Meticulously cared for.

However, it seems to have the common issues with the card reader. The motor starts but will not engage a card. There was a little bit of squealing at first but this quieted down. Guessing this was the clutch. So based on reading the stuff in the MoHPC knowledge base area, this is most likely the gummy wheel problem.

I'm a bit nervous about tearing into it without doing my research thoroughly, so I thought I'd ask around if there is any updated knowledge on this repair beyond what's already out there.

Thanks!

Sean
