Sheldon lathe "U" drive

[abunai]

Starting to try to restore a Sheldon LWQU lathe.
I'm trying to find a manual, parts breakdown, and how the "U" drive works.
Did some searching on the web and really didn't find what I wanted.
Didn't find anything on the "U" drive.

This is about as close as you are going to get to anything showing the "U" drive parts break down. Look on page 20 of 27

Edit: Here's another manual on the early M series lathes. Look on page 18 of 24. This "U" drive is used on both the L & M series lathes.
