ok for any one who cares or has the same problem use JB weld to fix the drive gear

I was at our model train show yesterday running my climax ,with 5 logging cars&bobber.I decided to run the 2-6-0 give the climax a brake , well it made it around the loop twice and died sounds like it has striped the drive gear(as you can hear the motor sing) .what can i do to get it fixed or can i regear it to match the rearing of the climax as my line is not a high speed railway and it would be nice to be a bull to use it as a helper on my steep grade
