What was wrong with the motor?? Did it just quit working?
I had one quit ~3 years ago, I narrowed it down to the motor but had to head out of town. My wife was driving the RV to a friends house so I went ahead and ordered a new motor and had it shipped to her friends house. Her husband installed, no big deal. I told her to keep the old motor.
Probably 6 months later I got a chance to take the old motor apart. The Power Gear motor has an electric brake on one end. When I took the motor apart I couldn't find a problem. Put everything back together and tested using a battery charger. It worked fine. Reversed polarity and it worked in the opposite direction.
It might pay to take it apart, look for a problem, and put back together. Never know, you may get lucky.
