Traxxas Velineon Motor Issues

Well, when I first discovered that I was having heat issues due to overpowering the system, I re-geared it and cooled it waaaaaay down.  I have been really careful to take good care of it, but I knew that it was only a matter of time before the motor failed.

Luckily, only a bearing failed, and whats funny about it, is another person I was talking to, told me that he had changed his bearings already, and his was only a month old.

Now, I am stuck with a motor that is in pieces, until they hobby shop gets a new set in, cause the guy I talked to at the track, had bought the last rebuild kit.

I believe my bearing failed due to heat, because when I tried to get it off the motor shaft, I discovered that it was melted/rusted onto the shaft.  I still haven't been able to get it off, and I am afraid to use penetrating oil because I do not want to damage the magnet's protective coating.

Also, when I examined the motor casing, I saw no heat damage, so I got lucky there...
