    What's serial number and build date of the machine? What type of drive did it originally have? It's hard to read the data plate, it doesn't look like that for motor/generator (MG) drive machines. In...

    The 3kVA boost transformer is an Acme T-2-53013-S. Its two 240V primary windings are in parallel and the two 120V secondary windings are also in parallel. I think that makes the no-load boost voltage...

    He also said that he appreciated the fact that people here were concerned about him and indicated that he was going to try to get back on soon.

    That line is the overflow for the center reservoir. You're looking at the fitting that threads into a tapped hole in the left/back corner of the headstock. If you take the top cover off and look in...

    The guy with the DC panel parts is still around. He's going to see what he has left. At one point he had two sets of 598 forward/reverse contactors and three field acceleration (FA) relays.

    Rich,

    I added your diagram to post #15 and I'll delete the other thread where you also tried to upload it.

    There's something REALLY funky about the file format that your iPhone produces. I...

    Definitely an exciter problem. If you're lucky, it just needs to be flashed. Go through the procedure an let us know what you find.

    It's entirely possible that someone replaced the ball thrust bearings with roller bearings and that accounts for the gap at the dial. Maybe someone with a square-dial will pull out theirs and measure...

    Roller thrust bearing? The ones that I've seen use ball-type thrust bearings.

    Is the backlash the same all along the screw?

    Does the gap in front of the dial change?

    Have you had the saddle and apron off yet? If not, it's highly recommended that you pull them. It only takes an afternoon to go through them. Before you put the saddle back on, you can block up the...

    Make sure you tell us what model lathe you're asking about.

    If it's a 10EE, I'm not aware of any backlash adjustment. If the dial moves in and out, you may have a problem with the thrust bearings....

    I'm not aware of any new replacements. I reached out to a guy that has some DC panel parts; we'll see if he responds.

    What you need is a Cutler-Hammer bulletin 598 relay. They were used in square-dial 10EE DC control panels for both the motor/generator and Works in a Drawer (WiaD) drives.

    I don't suppose that there are any tags on the leads?

    Way out of my area of knowledge here, but if you spin the exciter with the leads disconnected and read the voltages across each pair, that...

    Mike C.

    Does anyone know how to get hold of Mike C.? He hasn't posted since the end of March and his message box is full. Hopefully he's OK.

    The exciter is designed to put out a constant 115 VDC at varying loads. The series field, in series (as the name implies) with the exciter's armature, increases the field and therefore the output of...

    Does that only happen at high RPMs? If so, it sounds like the exciter voltage is dropping enough that the contactor is opening. If it's now happening at all speeds, it's an issue with the hold in...

    I wouldn't expect the voltage to go down when you jumper around the resistor. You might check the field current.

    I assume that you checked the resistances of the windings.

    It's possible that...

    That's definitely not the original resistor. Take it out of the circuit and see if the voltage improves.

    The problem starting at 2500 RPM is because your FA relay isn't working.
