What should a max temperature be and what gets affected with high temp?

The motor is a brushed 27t, rebuildable with bearings. What should I inspect to tell if its ruined or should I just toss it and get another?

Thanks, Lee B.
Tear the motor down and check the fitment of the endbell, bearings and the windings on the rotor. If the windings are burnt you can get a replacement rotor, and rebuild the motor. But if the whole drivetrain is binding you should also tear down the diff and see if something is bent in that assembly. I've never seen the drivetrain get bound up just with the motor being a bit off.
