Lennox G14 pulse furnace

I actually have a dead blower motor(the AC unit runs OK outside the house). It smells a bit of burning. The squirel cage turns freely. The capacitor is OK - I tested w/ my pro capacitor tester.
BUT how do I remove the motor or the whole blower? I think I've already removed the wrong bolt(there're 2) holding the blower assembly. Help !

G14 is an old furnace - please get the heat exchanger pressure tested before throwing good money after bad. The pulse runs under positive pressure, meaning that a heat exchanger leak can easily cause monoxide poisoning.

Modern furnaces are safer and quieter - they run under negative pressure.
