You must remove the furnace.
Then it's a piece of cake to replace the motor, well, sort of.
While the furnace is out, remove the burner log, and remove all the dust and dirt, and rust as well, that has collected over the years, in the combustion chamber.
You will remove probably a couple of cups full of junk.
Remove the oriface and clean it too.
Then replace the motor with the necessary gaskets as well.
