But it doesn't explain the only two hot wires and a neutral. I've never seen something like that and neither has anyone who has helped me work on it.

Just because they are white, black and black doesn't mean they are two hots and a neutral. That's just what wire they used when they hooked it up.

I didn't cut them. I guess the hack that got hold of the RCM did that then? In the one picture the blue and black are sticking out of the solenoid housing cut at an angle. That's why I mentioned it. Can I see rotator the wires? If there's only two my 208-240 hunch may be right after all. I'm not an...

Also as a side note it's wired for 480V 3 Phase. I have some pi coming tomorrow of the progress.

What's wired for 480v? The coils on the original starers are 240V.

It looks like only those 3 wires were
Disconnected. I would be VERY surprised if there is something wrong with it.

I haven't figured out why people say to pull the key out.
Just deal with pulling the rotor. The key will stay in the shaft or come out with the rotor.
You won't be able to get the key out by itself. I have never tried to pull a key by itself before pulling a rotor or bearing etc.

I have 4 or 5 of those rotator driven gears. They are new old stock parts that were never used. If you want one let me know. I'll let one go for cheap. PM me if you are interested. If you need the drive gear I'll include that with the big gear. As for age. From the looks of the RCM I'd guesstimate e...

Timers don't output any power.
They are only timed switches.
