The set screw on my attic fan blade can off, which caused the fan blade to rattle around and broke the fan blade - I had to replace the motor since the shaft no longer spun true. Ordering the motor was easy. It is a A.O. Smith OLM6151 1/10 HP, RPM 1550 motor.
The tough part I running into is finding a proper fan blade replacement. I know that the blade must be properly matched to the motor for decent air movement and not overloading the motor. (Thanks to A.O. Smith Motor Mastery University)
Thanks in advance.
