How do YOU clean your motor?

[Leet TC3]

I first spray a good cleaner into the motor thru the mounting holes until the runoff is clear, wait a few minutes and do it again. I then take a Q Tip dipped in Iso Alcohol and clean the motor brushes.

I now read that some recommend spraying the cleaner into the motor while the motor is running. While this seems like a good idea, I had always thought spraying liquid into live electrical current was not a good idea.

What do you do?

I don't clean my motors, per se.
When I tear them down to turn the comm and/or change brushes I knock any loose dirt out, wipe the inside with a towel, and put everything back together.
Of course if you are playing in water/mud you may need to really clean it out. Motor cleaner is hard on bearings as it removes all the lubricants (the factory lube is better than any oil).
Motor spray is great for stock motors, though, I suppose.

Jeep, Who told you that factory lube is better than any oil? With most bearings, the best way to make them smooth is to blast out the factory grease, and replace it with lighter oil. I either take the motor apart and spray the various components sepeartly, or if it is really dirty, then I will just spray threw one of the mounting holes, then blow out with compressed air. That usually cleans it out pretty good, then I take it apart, true the comm, replace brushes, center the arm in the magnetic field, then break in the brushes on my t30. that's it.

Wow you guys go all out. All I do is I take the brushes out, spray inside both brush hoods and while it is still dripping I spin the armature with a pinion attached, I do this like 3-4 times and then I clean the comm with one of those comm cleaners, I have no clue what they are called, comm sticks?

I do the total disassembly thing after a day of racing. I use a com stick on the com, motor spray on everything. I have to take care of this stuff, it costs to much to replace!

Have to remember not to touch the com from now on...

Anyone use the Black Death Comm drops? man, those things make a serious mess. I tried those, and was cleaning the motor between every race. I didn't even notice a difference with it. Just curious.

[Rick Hohwart]

Jeepinator has the correct technique. The grease in the bearings is designed for high rpm applications and should not be removed.

I thought that I was a clean freak buy disasembeling my car and motor once a week but some of you guys realy go all out, amazing! :eek:

[mavrick0611]

i disaemmble my motor, spray it down a few times with motor spray and reassemble it, i really need to get some lube for the bushings.

[Throtl Hapie]

I don't. :eek: I really don't care for motor maintenance. My p2k has probably 50 runs on it, oh well, I don't care if it burns my finger when I touch it. :)

when i clean the motor after a few races i: take the motor apart clean everything with motor spray seperatly. cut the comm. replace the brushes, reasemble the motor and brake the brushes in on a dremel. clean out the motor with motor spray again and relube it. inbetween heats i take the motor out of the car and clean it with motorspray through the brush hoods. Then clean the brushes with a pencil eraser and clean the camm with a comm stick. then i relube the motor.

The most important thing when rebuilding a motor is that you do not touch the comm with your fingers, it leaves oil on it, and you cannot buggy blast it off, i did not know about it until a fellow racer told me, the next time i got my comm turned, i was extra careful, not to touch it, i noticed a definate increase all around. I change out brushes, spray the amerature down, spray out the can, spray off the endbell, and put it all back together, and break it in with a 4 cell pack, while facing a fan. I relube the bushings, and that is about it.

[J mAn]

the thing you use to clean the comm is called a comm stick. i tried using black death comm drops last week i noticed a little increase in speed. they dont make a mess though. all this motor talk reminds me i have to go cut the comm on my GM3 arm

[steveaggie]

I take out the brushes and use a comm stick on them as well as the commutator. Then I give the motor a good spray through the holes in the can. Then I put some oil on the bushings, and some comm drops on one of the bruhes. Then I reassemble. The most important thing is to clean the comm and the brushes. It makes a big difference.

[bryceanator]

i clean my motor by first taking it apart and wiping it down with cotton swabs and rubbing alcohol on the arm and the inside and outside of the can then wipe down the end bell then put it together and spin it on the dremal at 1-4 with the comm stick in with a small squirt of motor spray and the muck spays out i usually give it 2 or 3 small squirts then use a white pencil eraser on the brushes then wipe them with rubbing alcohol
