That's to give the brushes the right form and if you do it under water, the dust will not settle inside the motor...
Mind the volume please : Started out as demineralized water... |

I think I did a total of 7-8 minutes. Possibly a bit longer... Before trying it, I actually mailed the guys at Lrp to check. They said it was fine at 3 Volts and with demineralized water. After that I opened it up, dried it out with a hair dryer and oiled the bearings a bit. The nicely rounded brushes afterwards : Not a great pic... |

this link dispels a few of your suggestions. not that i know any different but it says leave it in for an hour and dont strip it after as it disturbs the brushes.
i am not arguing or disbelieving anyone as i have no clue whatsoever but it seems to be another topic in which nobody can give a definitive answer. dc motors in water |

The proof is in the pudding - looking at the picture, the brushes look round enough after 10 minutes.
And they are high quality (hard) silver ones. Most reports I've seen do it even shorter. An hour is way too much... Other than that I agree with most everything else. I like to take it apart though without removing the brushes completely. And like mentioned before, dry it out with a hair dryer and oil it up. Could be done with just the hair dryer on a non-rebuidable I think... |
