Leica GZ6 Stereozoom Microscope

Broken Leica GZ6 Gears.

Been repairing quite a bit of discarded equipment recently – it’s yielded some good finds. Pulled a broken Leica GZ6 outta the trash- with cracked plastic gears (apparently like every other GZ6).

It was super easy to disassemble and remove the gears – which I tried to super glue back together and use. The glue didn’t hold and after trying to find replacement gears at SDP/SI. I started googling for replacement microscope parts. After quite a bit of searching (which I why I’m posting this) I found them at Reichert.

All told, around $40 for a sweet stereo zoom microscope. It had eyepieces and part of a stand. I gotta build a stand and an illuminator, then I’m set.

    My story is exactly the same (right down to the super glue). Thanks for the excellent info.

    I purchased the new gz6 gears…and now that I am reassembling the unit my memory of how it goes back together is failing me…I cannot find any diagrams of the zoom assembly anywhere…can you provide any assistance…there are two small clamps…one black one brass…and a small spring washer that are in question.

    but I have to change the gears focus
    I tried to remove the grains that are on the knobs
    but the same does not come off.
    You know if you have to do something else before?
    thank you in advance.
