Well, I've split the fan as suggested. Oiled the bearings and checked the wiring. No cracks. When I turn the fan on it doesn't start and I hear a faint hum. Took the box that covers the the controls off. What is this silver thing? Could it be the problem? Sorry double post :hammer:

A starting capacitor, which considering the age of this fan, is likely to be bad. 

They are available from local a/c and heating shops. Cheaper from Grainger and Johnstone Supply. Even cheaper from ePay.

Your old one shows to be 4mfd at 370volts. If not available, 4mfd at 450volts would be okay.

Does the motor shaft spin freely when spun by hand?

It must spin without much resistance or the motor will not start. It likely has self centering bushings which got cockeyed when you took apart the motor. Loosen the motor bolts and loosen the end of the motor as you did when you took it apart. Now evenly and lightly snug up the motor bolts in a cross pattern. Firmly tap all around the rotor shaft with a wood handled screwdriver or equivalent to center the bearings. Give the shaft a spin, it should spin freely, if not start over. When it spins freely, tighten a little more in a cross pattern, and tap again. 
Repeat this process until they're tight. Some motors are finicky and some I've had to take apart 3 or 4 times until it came out ok. The shaft will and must spin freely by hand.

Lane, when spinning the motor, should I place the blades back on and spin, or  just spin the shaft with my thumb and pointer finger?

No blade needed. Just spin the shaft. It won’t coast for a long while but should at least coast for a few revolutions after you let it go.
