Hello
@CES1979,
First, welcome to the group!
What's the state of your Maximat 7? Is this a total rebuild/re-furb, or just a small repair?
We love to see photos here, if you can post some.
About the gear; Do you know the exact specs?
If so, you may be able to 3D-print it at your local library, maker-space, etc.
You would need to know the diameteral pitch (or module if metric), tooth count, thickness, and centre hole dimensions.
Fusion 360 (free for home use) has a built-in "wizard" to generate the STL files that the 3D-printer slicer needs.
I wrote a little about it here:
https://www.hobby-machinist.com/threads/has-any-body-tried-these-threading-gears.75340/post-642147
If you can provide all that, I could even 3D print the gear for you.
The only thing I ask from you is an honest public review (posted here) of how the part holds-up in use.
It's all about learning.
(it's the same deal I made here:

I have some of this filament in stock:

........and it sounds like it would do the job.
Let me know, you can Private Message me (hover over my profile picture and hit "Start Conversation") or reply here....but you can't be in too big of rush....so many projects!
