How-to: Maintaining your Brushless Motor (LRP X-12) Your motor is important when it comes to racing. If your motor doesn’t work like it should, you will never win the race (or you have to be very lucky). Most people think a brushless motor is maintenance free. But there are actually a couple of thing that you should do to keep your motor in the best possible shape. What you'll need: Hex screwdrivers A brush or toothbrush Bearing oil Rag or paper towel Compressed air (optional) Here is a picture of the motor disassembled, each part of the motor is named, I will use these names in the article so you will know what part I mean. Step 1: Unsolder the wires from your motor and remove the sensor cable. Step 2: Remove the gear cover so you can access the gears. Remove your pinion and the screws that hold your motor. Step 3: Take the motor out your car and clean it with a brush. Step 4: Remove the middle screw and take the plastic endcover of the motor. There could be some dirt in there so take your brush and remove the dust/sand. Step 5: Loosen the 3 screws that hold the motor together and remove them. Step 6: Take the front housing of and take the rotor out the stack, clean them both with a brush. Step 7: There will be some dirt on the bearing in the front housing so first remove the dirt and then lube the bearing with 2-3 drops of bearing oil. Let it sit for a minute and wipe the bearing with a clean rage or paper towel so the left over oil won’t attract dirt. Step 8: Remove the ‘PreciSensor Assembly’ and clean it with a brush. Step 9: You can pop the bearing out of the stack, also clean it first with a brush and then lube it with bearing oil, let it sit and wipe off the oil with a rag or paper towel. Step 10: Assemble your motor back together, don’t forget the little shim(s). Just to let you see what dirt and sand can be in a brushless motor. This is the amount that I managed to get out my motor.
