Get off your high horse, Bill.

I followed Madman's suggestion to make my own bearing puller (see picture). I screwed the nut on the shaft, put a piece of hardwood on it and gave it a few wacks with a hammer. It went out pretty easily. Thanks for the tip!

I wonder if i could use the same set up, turning the rotor upside down, and tap at the other end of the shaft to install the new bearing.

That was my bit of southern engineering... )
See the picture below on how I put the new one on. I used a 5/16 or 3/8 socket over the bearing inner race and tapped on with mallet. Make sure motor shaft is on wood to prevent mushrooming it.

If you do not have a socket deep enough for your shaft, a small diameter piece of pipe will work, too. You just want to hit the inner race.

Hey, I like the homemade bearing puller! It's literally exactly what I had pictured in my head when I described it. I suppose you could use it 'upside down' to install the bearing, but I'd definitely do like texaskirbyguy says, use a deep socket or a pipe. A 6 inch 3/8" pipe nipple should be easily had at any hardware store for a couple bucks. Would probably be about the right diameter.

A few years ago, I found a 10 mm deep socket on the pavement, walking down the main street in Granby, first city at west of Waterloo. Back home, I put in in a drawer with other sockets, saying to myself that it could be useful some day.

Well that day has come, it was perfect to put the bearing back on the shaft !

Bearing of second motor is a lot more stubborn, I have put penetrating oil 2-3 times since yesterday but it doesn't seem to do any good , I'm still unable to remove it.

So that's where my 10mm socket went... (mechanic's joke)

Push comes to shove, you could just find someone, or some business with a hydraulic press and ask them to press it out for you.

Well , the second one finally came out, I had to install my bearing extractor on something more stable and solid, i.e. on pieces of 4X4 laying directly on the concrete floor. I got it out at fourth strike.

I had a hard time installing the new bearing in the fan housing, for some reason it didn't want to slide straight in the housing, it was always going in at an angle.

I hope you get it running i love my AP200

I'm confident it'll work, I swapped wires with good connections from a donor AP-100 with a dead motor and a cracked body, it's just a question of time.
