It takes a little doing, and is a rather crude tho' effective method. Google: " compass for motor coil polarity "

I sure hope you roadmapped everything you took apart and unhitched...:)

Obtain the following:

A small decent quality compass, and secure it to a non-magnetic probe. soild #12 romex works well...
A Transformer to reduce its normal voltage to 24 ac. This so you can work short term without frying your windings.

Energize the coils, preferably through the normal speed switch, dip the compass into the center of the armature hole The compass will indicate polarity of individual coils...north or south if checked in turn around the stator...

Edit... If your polarity checks ok, you can be sure of rotation with the following:

Obtain a short piece of 1/2 " copper tubing that will fit within 1/4 inch inside your stator. Drill an adequate hole in the exact center of the tube, so that it will rotate on a piece of indulated #12 Romex. A cable tie on the end, and a small washer, will provide a good surface to allow the tube to spin freely.

BRIEFLY apply operating voltage to the High windings section of the switch... the tube will rotate in the direction your armature will, in the stator...

Good hunting !! :D
