[HELP] XL Motor Wobble

[pint14]

So today i i switched on my BB in moc, which hasn't moved about a year. Then the problem occured: 1 xl motor worked fine, but the other not. So i took motor out and tested it. Motor run's fine in one direction, but if you switch it to other direction, it wobbles for 1-2 seconds and then stops, beacuse BB switch itself automaticly off. I opened the motor, but i can't see ant problems. Do you have any ideas?

Seems like something is jammed in the gears, or such? Does the motor part without the gears rotate normally?

I removed those plastic gears, but the motor still runs for 2 seconds and wobbles in the same time and then switches off. The problem should be in the electric motor i think.

EDIT: if it's helpful i can make a short video about the problem.

It seems like the XL motor is maxing out the voltage of the BB. (That happens to me with buggy motors)

It appears as though there's something jamming the gears as Zblj said.

Well as i told you there's nothing jammed in the plastic gears and i doubt that there are any more gears inside the electric motor.

Does the motor rattle? I had a bad motor once, where a pice of comutator broke off and lodged the rotor.

Did you also try a different power source?

That motor is trashed. If its a commutator problem then there is nothing you can do to repair it.
