Answer 4

If there is one realy long bolt going thru the center of the armature, it has a tappered crank shaft.

These can be quite the project to remove.

With any luck, you may get it to "pop" loose.

Remove the center bolt.
Now, place something like a 2x4 under the machine to place it at a slight angle tilting the generator upward a little.
Spray some "penetrating oil" down the center where you just took the bolt out.
Let it sit for a while so the penetrating oil can seep it's way in. 15 minutes or so.

Now, place the the board under the other end so that it tips downward. Some of the penetrant should drip out of the end of the shaft.

Put the bolt back in hand tight all the way, NOW, unscrew it three turns.

With a fairly heavy hammer, hit the end of the bolt. Not more than three times though.

What you're doing is just trying to get the two shafts to knock free from one another.

Check to see if you can jiggle the generator end a little. If you can, take the bolt out, and pull the amature out.

Good luck, you'll need it.
