Cleaning Brushless Motors

[Jtg.73]

I know I posted this a while back, but I am going to double check. 

What is safe to use on brushless motors?  I only ask this because I have some Dynamite Magnum Force motor spray which I use on my 13.5 in the summer and after that I had problems with  the motor. Perhaps I did not reassemble it properly, but I doubt it. There is not a lot of parts there.   Doesn't say on the can about not using it on brushless motors.  I did clean that motor two or three times with this cleaner before there was any problems.

Look on youtube there is a video of how to clean a brushless motor...by speedpassion....most are the same but be sure to reinstall the shims as they come out of the motor.  http://www.youtube.com/user/rcspeedpassion#p/u/17/6iFTO54uGM0

What's there to clean?

I know they are a lot cleaner than the old brushed stuff. I figured they needed to be cleaned a little bit though.

You never clean yours?

the only mechanical parts are the bearings and thats all I have ever cleaned...

  the way i do the motor cleaning is i rarely take my motor apart unless i can hear something in the motor, otherwise i only spray the bearing from the outside and use a soft bristle brush to clean the bearing area. once and awhile i will spray the motor cleaner in the motor when there is a dusty track or a fuzzy carpet track. you can tell if something is not right with the motor when you spin it, if it sounds funny then take it apart and make sure that all the part come out the way it was installed especially the shims. you might have a small shim from the rotor jammed in between the rotor and the can make sure you look at the can itself with a bright light and i bet you will find something in there. and a little motor oil for bearing is a good idea to at least a couple time on a race weekend. the only concern is make sure you don't over heat the motor because if you do the motor is on its last leg and that is another reason why your motor might not be running right. a good temperature is 150 deg *f......if you get the motor over 200 you might want to check the gearing one more time or get someone to help you set up the speedo or maybe a car setup might help.... and its all trial and error with rc your always learning something new.... i hope i helped you out with some answers you were asking about motors.....
