It's a great little motor for the 19 turn class, or if you want to play around the yard with more power than a stock motor.
Taking it apart and maintenance isn't bad at all. Unhook the springs and take the brushes out of the hoods. Take the two screws off that hold the endbell on, and carefully slide the endbell off. Pay attention to how the shims are stacked on the armature. You can then clean the motor with electric motor cleaner, have someone cut the comm, and then put it back together.
There are 1001 different opinions on the maintenance required to get the most power from an electric motor, but only serious racers need to worry about that.
