Wish I could help.
Probably a hot and a neutral, one or the other should be moved, not both.
Don't know which.

Without a lot more info, we can't help. Most electric motors have diodes and capacitors as part of the circuit. Simply reversing the wires could explode an electrolytic capacitor.
It also depends if it's an AC or DC motor. If it's an AC motor, switch the leads won't do anything except potentially put the "hot" lead on the case which could be fatal.
It will be cheaper and easier to just buy a motor that spins the way you want.

If it's a 3 phase motor just reverse 2 of the feed legs . Single phase is more involved & on some not possible . Try calling motor mfger & ask .

If you don't have access to the internal leads on a single phase motor it's non-reversible. Normally it's leads 5 & 8 internally that you swap for a single phase motor.

At work, for gas furnace 110VAC motors, we would unbolt the casing and reverse the shaft and reassemble, usually a five minute job. For 220VAC motors we usually had the luxury of reversible motors (just swap two marked wires).

From My early days at Hobart Food Machines the motors were reversible. They had two fields and if I recall it was 1&3, and 2&4 for one direction and 1&4, and 2&3 for the other.

Some of the older motors had a lever in the rear of it that switched the brush frame to reverse it. I don't know much about it.
If you are runniing a pulley and belt on the motor to another on whatever apparatus,,you can just take a slightly longer belt and figure 8 it and put it back on the pulleys. That will make the apparatus run backwards.
Usually have to move the motor mount a little off from center to avoid the belt from rubbing on itself as it criss crosses.
Other than that, I know nothing about elec'teric motors.

If you have a plate on the motor with the model #, speed, voltage, frame #, please take a picture of it and post it. We can probably help you. Right now you haven't given us enough info.
OP
Solved
The motor belongs to my neighbor. He solved the problem by moving the motor from the left end of his workbench to the right end.
Now, the rotation is DOWN for ease of buffing. The buffer has to be at the end of the table with the wheel overhanging to allow for buffing large pieces (like motorcycle engine parts).
Thanks for all the responses.

I was gonna say "flip it over", but you guys are faster than me.
