Good motor maintenance is crucial to peak performance. The two basic needs of any motor are keeping it clean and keeping the bearings oiled. Your other thread asked about comm truing. This is usually something the pros do but anyone can benefit from such a procedure. Make sure your brushes are in good shape as they will wear faster than any other part of the motor. Take a look at your springs as well, replace them if needed. A quick way to clean your motor is running it in a glass of water. That's right, in water. Make yourself some sort of connection that will allow you to submerge the motor in a glass of water and still be able to connect to a battery pack that's kept away from the water. Running the motor in water for about 5-10 seconds at a time will do the following. It will clean alot of crud that has built up inside around the bearing, the magnets, the brushes, and the commutator. It will also true the surface between the brushes and the comm. Not as true as one done a machine, but it will condition them some. Make sure the pinion is off as alot of water will spin up from the motor armature itself. No need to make it worse with a pinion. You will see the oil and dirt accumulate on the surface of the water when you're done. Make sure after you're done to completely dry it out (blowdryer works great), and the re-oil both bearing ends. Good luck !!
