    I don't know when they changed things so that you can't download the pictures.

    If we're talking about the box that's been grafted onto the tombstone on the front of the headstock, that has nothing...

    I don't see any need for it either. I also haven't heard from anyone else who had a wire C-clip on their leadscrew. I could be that someone on third shift put one on when it wasn't supposed to be...

    Even if you could find a source, I would steer away from them. I had one of those damn things on the right end of the leadscrew on my 10EE. It was behind a stamped steel cap that had no provision to...

    I does appear that a 2-pole switch was used. If you look at drawing EE-3216, the section of the "Elementary Diagram" in the upper-right corner shows the drum switch and pump motor. Power for the pump...

    Tom,

    I assume that these are in the end of the base casting, above the big cover for the exciter end of the motor/generator. Those were probably for some user-installed accessory, perhaps a collet rack or...

    If there's no run capacitors, I think it's derated to 66%. Properly balanced run caps will improve that.

    You could test it by using a manually operated switch to temporarily connect a starting...

    Correct, Mobil. No, their tech support won't be able to help you here.

    Sundstrand is still around (link). Have you tried them?

    Mobile has gone through a progression of names. It started out as The Vacuum Oil Company in 1866, became Socony-Vacuum Oil, then Mobile, now Exxon-Mobile. Over the years the products have also gone...

    That's a pretty cool chuck, but it looks like you'd be into it for over $4k, not including backplate.

    Have you considered using soft-jaws, bored to the correct OD? If you bore the jaws and don't remove the chuck, it will have zero runout.

    Depending on the what the part is, a large diameter,...

    Based on the connections, it's probably a standard dual-voltage, 9-wire motor, connected for high voltage:

    If you've got a rotary phase converter or access to 3-phase, you probably won't...

    Since this is an hydraulic drive, I think I would go with Mobil DTE 26, ISO 68 hydraulic oil. McMaster carries it: McMaster part #2158K13

    I'm 99.9% sure that's the right coil. I have a photo of a 440V 60CY starter coil that has "464-3" on the second line; yours is "464-2". I'm guessing that the "464" is the coil form and the "-X"...

    I think that if the combined weight of your 10EE tooling exceeds the that of the machine, you qualify. :D

    I think that you have everything. The other dial like this that showed up (on EE27264) was an accumulating dial, with an extra ring/dial and a gear train that rotated the secondary ring so that you...

    The original 10EE AC contactor/starter is a Cutler-Hammer (CH) No. 9586H1990A6, size 1. Bulletin 9586 covers a whole bunch of options. Unfortunately, I've never been able to lay my hands on a copy of...

    Probably to the coolant pump. Look in the compartment behind the big cover on the back and see if the pump is still there.

    The serial number is "MFGR'S NO." on the build plate:

    I can't make it out, but it should match the number on the brass plate on the DC Control Panel cover, which looks to be 13066 or 13068....

    Nice score! You would probably pay almost that much just for the tooling.

    The speed control knob is definitely not stock.

    I would like to see pictures of the drive system. Including the motor...
