Cecil,

If the replacement motor turns the wrong way, you should be able to reverse the direction be flipping the leads on the windings. This will reverse the polarity on the coils and make it run in the opposite direction. I’ve done this with AC motors for various things.

Unfortunately I lost the piece that was broke off.  I found a new motor 
today, and will get the old one rebuilt.  I spent a couple of hours 
adapting an old ford starter motor to fit, then found it turned the 
wrong direction.  New motor was $254 with bracket and pulley.  A new 
motor on Ebay was $248, so I don't think it was too high.  Then I had to 
work on the outlet chute.  The metal is really think and due to the salt 
in the feed it is rusty..

If there is enough room you can glue on some plastic reinforcement to the outside surfaces or give it a coating of epoxy. It may last long enough to get you through your work while trying to get a replacement.

Sometimes you can simply dry out the unit by separating it into its two main parts and baking them in an oven for a short while at a low temperature to remove any moisture. Then put it back together and test it on a bench. Don’t let the parts get too hot or you may damage the insulation on the wire and there’s no coming back from that. All you really want to do is try to remove any moisture.
