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.
