Here is motor cleaning howto I wrote for another site, though you guys might get a kick out of it or even give me some tips!
I know that allmost everybody knows how to do this allready, but I though it would be neat to write a howto. Plus it keeps me away from the sauce.
and I might even get some tips!!!
Here are all the tools we need to clean our motor, most important is the small philips screwdriver.
Here is the motor we are going to be working on, last weeks a-main 3rd place truck OPEN motor. no its not a stock
We can now start by pulling out the brush springs and then pulling out the brushes.
Now you can loosen the two small phillips screws that hold the endbell on, then remove the endbell from the motor(MAKE SURE YOU KEEP TRACK OF THE WASHERS!!!!!!!). Once the endbell is removed you can remove the ring inside the motor, then you can finally pull out the arm. here is my motor completly taken apart.
Once you have everything taken apart you can now hose everythig off with motor spray, Motor spray is highly recommended because it is gentle on electronics I have seen some people use brake cleaner for cars but this may harm your motor
, I usually spray untill the runoff is clear.
wicked cleaning action shots!
Here is our icky arm, this one has roughly 30 runs on it(all at tchr!!!!), you can tell that this guy is ready for a cut.
Now we get to bust out that expensive lathe and get ready to cut the motor, I wont go too in depth on how th use the lathe in this howto but I will show you pics of the general process.
Here I have the arm in the lathe and am oiling up the v-notches so the arm spins oh so nice
Here I am marking the comm with a marker to get ready for the cutting.
Here is a crappy pic of the comm after I cut it, you can tell it looks much better now
After you cut your comm you always want to replace your brushes, here we can see the old brush on the bottom and the new brush on the top, man that old one looks nasty!!!
You can now go ahead and reassemble your motor by placing the washers on the arm then placing it in the can, after that you can place the endbell holding ring back in the can then place the washers on the comm end of the arm then re mount the endbell. Now you can replace the brushes on the motor, and last but not least you can oil up those BALL BEARINGS
