Motor Component Identification

I am sure somebody here can help. I found a motor in my bits box, I think it hay be off an old Big Haulers 10 Wheeler, the early battery powered model (9 volts), however there are two similar components (circuled in red) connected to it that I am not sure what they are or what they do, they look like wire wound resistorsMotor.jpg.
 
Those will be inductors. - Noise suppression components..

I would be wary of the large can-like component.
It looks to be an electrolytic capacitor. - These are normally polarity sensitive, and should only be connected one way round..
Check to see if it is marked with a black-band, or '+' symbols, by one lead. This will indicate that it is a polarity sensitive component.

I assume you will want to run in both directions? If so, just cut this component out.
As for the rest. They should not do any harm, and may help. Whether you leave them, will possibly depend on the space available, at that end of the motor, within the model.

I concur with Phil.

Inductors are used to block AC (such as noise) but pass DC, and capacitors are used to block DC, but allow AC to pass....
 
Back in the day, that sort of kit was installed to prevent interference with yer TV - so that you didn't incur your parents' wrath every time you played trains >:)>:)>:)>:)
 
The large capacitor should be a non polarized capacitor if the engine can reverse direction.
 
Yeah, if it's from a Bug Mauler, then most of that is after-market add-ons.
 
Jimmy, is that from a battery operated Big Hauler? That kind of suppression equipment was common, since the motor noise interfered with the wireless remote control.

That kind of stuff was way later also in the track power units, but said this was old.

That is a first or second generation unit (pretty darn old) pre-1994
