Outside AC Fan not turning - How to lubricating ac motor?

My outdoor ac unit stop working a few weeks ago.. pressor is running but fan is not. I turned the unit off until it cooled down and turned it back on and the fan still didn't spin.I then gave it a spin with a stick and it started right up. This has happened twice now. I think the ac motor just needs lubricating but I don't know how/where to lubricate. Please help.

Answer:

the start capacitor in the motor needs changed.
Yep,... start cap needs change out. If the motor bearings are dry then changing the condenser fan motor is easy.... if you are at all mechanically inclined this should be no sweat.
Even it is written permanent lubricated,the shaft bushes became dry.Also the dust accumulated in the shaft near to the bush or bearing of the motor increases the friction and makes heat the shaft and bushing will make the blower to stop after a period of working. So try to put one or two drops of any lubricating oil. Use a syringe to pump oil to the shaft near to the bushing. if the problem reduces add more oil in intervals of weeks so the wick around the bush will absorb more oil for future lubrication
Yep you need a new capacitor. unfortunatly who ever you hire will charge around $150 to change it, 80 just to look at it
