I don't think i've ever seen a silver can die ...ever. But its not to say it can't happen. Usually the ESC's go first.
If it is your motor, you can get a brushed silvercan for super cheap..If you are sure its your motor I could mail you one for shipping only (assuming your in the USA). -I have like 5 or 6 silvercans all used but all working, i'd love for someone to get use out of them ...or just go on eBay and get one ...I think they should be like $15 or less (not even sure what they sell for ...haven't bought one outside of a kit in like a decade).
(just PM me).
I just bought a D sized battery and tried to make the motor spin with it. I can see sparkle coming from the lead when it touched the pole but nothing else happened. (Green negative cable was attached to the negative pole and yellow positive cable touched positive pole for less than a second)
I'd like to disassemble the motor to check rotor and stators. Is it possibile?

By the way if you want to change text or a whole website to a different language - try Babelfish, it really works.
After the impact, prop shaft was stuck and didn't spin (when I was waiting for the battery to be shipped, I spun it by hand to see how transmission worked) but diffs worked fine (if i was turning one wheel, the other one was turning on the opposite side). I dissassembled all the car to check diffs, gears, etc. but it was just when I detached the motor that prop shaft spun freely even by hand. I can't see any damage to the teeth of pinion, spur and diffs gears
