Atlas 7B Disassembly and Teardown! Pic Heavy!

Thanks for the info. So yours has oil cups or just holes?

I did notice the rounded over bits on the shaft but I didn't think it was really a problem. The final engagement points are unchanged so would it really matter that it's rounded over in the interim? I could probably dab a little hard face weld on there buy I didn't think it was very critical. Any thoughts?

Also there are some minor cracks in the ratchet housing that are in the back of my mind. Someone makes a 3D printed ratchet housing on eBay made from a heavy duty plastic. It actually looks like a decent option. I considered trying to fab a ratchet housing like I did for the feed gear housing but the ratchet one is much more complex and might not be practical. Not impossible though.

There is a guy on the Atlas Facebook group who has a homemade ratchet cover made from aluminum. He didn't even know it wasn't factory until I told him. I would try repairing yours. I posted a thread about repairing it in these forums. If I was you, I would attempt making one. I would make it from aluminum and I really dont think it would be that hard. Did you ever get the drawing of it from Atlas? I remember you got the drawing for the housing that you made.

Hey. About the wipers. I do have original rubber ones but they are rock hard and not really useable. I believe the deal was that the new ones are thick enough to not need wipers. I mean they take up the whole tin cap with the felt alone. I did get wipers for the table but I'll put them on when I disassemble and clean the table assembly.

Regarding the ratchet housing, I did get a drawing of the rear portion of it but not the front part, the part with the selector lever. I probably could make one, I may revisit the idea in the future.
 
Weldo. thanks for this thread with detailed description and pics(not to mention time). I have 4 7B's with one being partially disassemble....but not for long. I've been running a shaper going on 39 years and still amazed what these little Atlas shapers do. thanks again
