Can anyone point me toward disassembly directions for an Atlas MFC mill? Particularly how the table, y axis and knee are removed?

Thanks
 
I don't know that there are any written instructions for disassembly, although there are exploded views available in the parts diagrams that you can find online. From my experience, you will need to take the power feed drive assembly off the x axis first. This leaves the drive gear for the x axis on the leadscrew. Drive the pin from the right end (as you are looking at the machine) leadscrew, releasing the right drive handle. You can disassemble that portion of the drive and remove it from the table. Unscrew the hold down plate on the left side from the table and loosen the gibs and you should be able to slide the table off to the right. You can unscrew the leadscrew from the leadnut now. The leadnut should be held in the saddle with a setscrew. To remove the saddle, you will need to unscrew the y axis leadscrew assembly from the knee, then unscrew the y leadscrew from the leadnut to remove it. I believe that the sheet metal guards should slide or pop out. You will need to loosen the gib from the saddle in order to get it out. If I remember correctly, you will have to loosen another setscrew to release the y axis leadscrew, as the saddle will not come off with it in place. The knee is easiest, just unbolt the leadscrew boss and take the gib retainers off the back of the knee and it should lift right out. It's been a couple of months since I put mine back together, so this is all from memory, but it should get you started. One important point to note is that the geartrain of the rather fragile power feed gearbox attached to the saddle is only meshed into the gear on the x leadscrew, so once the two bolts holding it on are loosened, it should just drop down with no prying required (there may be some pins, I don't remember). Just be gentle with this part. I cracked mine because I got overzealous during disassembly, but it didn't hurt it's function and I am currently using it. Good luck.
 
Thanks very much! I just purchased it. I need to take it down to my basement workshop in small bites, and anyway it needs a good cleaning. Otherwise I think it is in good condition.
 
I was faced with the same situation -- mine was in good condition but I had to disassemble it to get it down into my basement. I figured that was as good a time as any to clean it and oil it.

If you take the motor, guards and countershaft off, it's pretty easy to carry down a flight of stairs with two people.
 
You will also find a number of files including the full manual for MFC, M1C and MHC and the parts manual on all models of the Atlas mill in our Downloads. Plus a lot of other files.
