Hi all,

So I'm am in a bit of a predicament. I was tuning up my atlas, and my retainer ring for worm gear retainer bearing was damaged. Now I need a replacement.  I can fab one as I have access to the tools but I dont know the thread pitch. I think the diameter is 22mm but unsure if its 1.0, 1.5, or 2.5 pitch. I doubt its 2.5 but I want to ask if any one knows what it is or where I can purchase replacements.

It might be easier to cut new slots for the spanner wrench. A thread gauge or a comparison bolt from a hardware store will give you the pitch of the threads.

As long as it still threads in, just clean up the slots with a small file and reuse it.

Welp update. Fyi image was the good one. The other one the threads got damaged. I contacted orion, I might be able to purchase them. For future reference M22 x 1.0. I am buying a tap to clean out the locktite and threads. Looks like I'll be missing the new moon for imaging big bummer lol
