4 pole motor

hello, looking for some help!
I took apart an old drill press, and like an idiot, i didn't note where the wires were connected. here's all the info on the motor: 4 pole, 1/2 hp, 60 hz, 110/220v, 8/4 amp, 1725rpm, 1 phaze, class A.
it is a 1986 orbit motor. can any one help me here?
there is a black, red and green wire to the plug, and black, red, yellow, and grey to the motor. the green is grounded to the machine. thanks!

Here are some diagrams:

Don't see any that match your colors.
Look for dual-voltage hookups if you search.
