can this motor be reversed? - Wild Turkey - 02-28-2017
Older 1/6 hp motor has 5 terminals. I reversed white and black and no change.
It has five numbered terminals -- 1 and 2 are left to right on top row; 3,5 and 4 are in bottom column.
hot and neutral are hooked to 1 and 3.
any ideas or am I stuck figuring a way to mount it so the wet grinder I'm using it on will turn the right way.

try crossing the drive belt.
if you have enough belt that works fine

No diagram under the cover? No plate on the outside case?

What does the nameplate say, i.e. dual-voltage? Thermally protected? Reversible (rotation box perhaps)?

Too small/old for anything but basic info on nameplate. If there was a wiring diagram it's covered with paint/crud.

[OT] I'd forgotten about that trick. From my childhood I remember an Allis-Chalmers pull type combine. It had a l o n g V belt (maybe 10 ft.+) driving several parts and had a couple reversals. Needed a diagram to install the belt so everything turned in the right direction.

The original Struck Kit Minidozer used that technique for reverse. I still have the Popular Science science magazine from the 60's which featured that little dozer.

If you're willing to take some resistance readings with a DMM, we can probably figure out if it's reversible.

If it turns out it can't be electrically reversed, there is a way.Remove the endbells and rotor. Reassemble with the bells and rotor reversed. You will have to extend the wiring from one side of the center housing to the other side. A bit of trouble to do, but it works. I have reversed several motors this way.

Mounted motor on other side to reverse the direction of rotation.
Turned it on and guess what -- now it runs backwards
only spent half a day mounting it.
