HP 67 Card reader repair

After some years of use the transport wheel for the data card has changed it’s function into dough. It produced a big pollution, because I try’ed to use the abrasive card to clean the reading head.

The article to repair the TI30 is one of the the most read articles in my blog.

Here is an article , not especially for the HP67 repair  in german,. Therefore there is a cut out of HP67 repair procedure for people that can’t buy the special tube mentioned here.  Please read the  translation:

After I could not find this said pink fuel tubing for the friction wheel I have used a  piece of an approx. 3 mm thick rubber plate of  tyre quality and grinded it round in a drilling machine until the diameter was 6.4 mm. Works great!
