HP97 printer gear replacement
After a long search, I found a supplier for the replacement of the rubber gear in Germany.
The bore I had to increase from 2mm to 2.38mm and with some sandpaper I had to reduce the thickness by 0.1mm. But now the brass gear runs perfectly. I have the running surfaces with little oil. Nevertheless, the printer makes noise as a saw. Now the supply for the European HP97 printers is ensured :-) http://www.modellbauershop.de/zahnraeder...3-30-z.php Produkt-ID: 390760 Price €11,25 Hans-Peter |

RE: HP97 printer gear replacement
By the way, you mentioned "european HP 97".
Are there diferences in the gear measures between the 97's? TIA |

Not only for the European also the other Countries who would be delivered from the company.
In the other case I will make a collective order for overseas HP97, if the delivery should not go. I think Geoff was already in a forum in the search for the gears and he wanted about 40 pieces, if I remember correctly. HP ;-) |

RE: HP97 printer gear replacement
This gear is a better replacement:
http://www.modellbauershop.de/zahnraeder...30-z-1.php It's cheaper and you don't need to reduce the thickness. But you still have to widen the hole. There has been a post about it: http://www.hpmuseum.org/forum/thread-601...l#pid53789 |
