Atlas Mill HELP!!!

Besides being more expensive and more prone to slippage, link belts do cause accelerated pulley wear. They were originally designed for emergency repairs to keep industrial machines running until time allowed replacement with a proper V-belt.

I'd suggest using a proper-sized belt instead of the link belt stuff, or one of those new urethane belts that you cut and melt together. The link belts seem to chew up the ZAMAK pot metal and aluminum pulleys.

I am interested in learning about this melted urethane belt system.

TDog,

If you haven't already done it, go to DOWNLOADS (instructions for navigating DOWNLOADS are in the Sticky area at the top of this Forum) and download Atlas Mill Bulletin MMB-5 M1--MHC Rev6.pdf.

To add to what was written earlier, in the right side of the large spindle gear (AKA Bull Gear) is the Direct Drive Pin. When the machine is in Direct Drive, the pin is pushed in so that the hidden end of it enters a hole in the right or front face of the pulley, locking the two together. Locate that pin and make a mark on the pulley with a Magic Marker in line with the pin for future reference.

After you have re-positioned the spindle components, pull the pin out so that the pulley is free to rotate independently of the Bull Gear. There is a special tool for that purpose. The factory drawing for the tool is in DOWNLOADS.

Remove the oil plug (there is only one in the pulley, not two, and it looks like a set screw) from the pulley and squirt some SAE 20 (ISO 68) Non Detergent oil into the hole(it probably hasn't been done in years). Reinstall the plug and briefly run the motor to distribute the oil. Repeat at least once this time only. In the future, if the back gears are used routinely, oil the pulley bushings before each use. Otherwise, oil them about semi-annually. The rest of the instructions above are correct except that the running clearance between the pulley and the bull gear should be about 0.002" to 0.004".

Please help, I can't seem to locate the drawing for the factory tool used to positionre- position the spindle pulley pin. Please post the link.

Thanks!
 
Although the tool drawing was added recently enough that you won't have to scroll through all of them, there are nearly 2000 files in DOWNLOADS (originally called Resources). Before starting to look for any file, in general you will save a lot of time by first navigating to the Category under which it will most likely be found. There is a Help file in the Sticky area at the top of this Forum. Read it first. Then in this case, drill down to the Atlas/Craftsman/AA category and then into Atlas Drawings and Atlas Mill Drawings before you start the manual scroll down the list search. The majority of all files in DOWNLOADS are sorted at least on Badge. Unfortunately, Zenforo has no further sorting capability. Which is one reason that I spent several months building the Category tree and then moving all of the files into it.

For some weird reason, the system isn't making the link above clickable tonight. But if you copy and paste it into your browser address bar it will take you to the Atlas Mill Drawings Category (Folder). And the file that you were looking for happens to be at the top of the list. And below it are only mill drawings.
 
Here are some pictures of the "back gear wrench" that came with my MFC. I have no way of knowing if it is original. Note the notch is rounded and the end is tapered, the supplied diagram doesn't show these features.

I've seen several variants of the tool. That one could be slightly modified.
 
I have some paper work on that machine. If you need me to copy & try to send it to you, let me know
