Blade removal 101

             Outside unit fan motor replacement tip

   Your central unit outside condenser motor is gonna someday die, thats a fact of life, will you pay some guy $450 dollars to replace a $75 dollar part? Or will you go for broke and fix that puppy yourself? One thing to keep in mind is the blade being attached to the worn out motor aint gonna wanna depart from it's dead buddy too easy. Ok maybe you got 50 bucks to go buy another blade and don't give a dang, but if you take your time and do it right, you can remove the old blade and save some suds money. Put the old motor and blade into a vise, get some sand cloth and start smoothing up the motor shaft surface between the blade and the motor, get it as clean as you can, then take a piece of hollow pipe about 6 inches long and place it on the hub being careful not to hit the shaft, you never want to hit the shaft, as it will expand and not allow the hub to come free, DONT BEAT ON THAT SHAFT ! Tap down on the hub of the blade, with the hollow pipe,into the cleaned portion of the motor shaft, and then, sand smooth the portion of the upper shaft you have exposed. Add some good penetrating oil and wiggle the sucker off using a large crescent wrench.Take your time and you will save money.

    On an inside blower again you NEVER want to beat on the shaft. This expands the shaft and makes it harder to get off. Take a hollow piece of pipe ( I use an old piece of 3/4 galvanized pipe) gently tap downward on the hub of the blower wheel after you have put a little Rust Buster on it and loosened the set screw. Then use a crescent wench to grab the shaft  and wiggle it free using a little more Rust Buster. Since the inside unit is never in the weather  the blower wheel should come off relatively easy.
