To add to the good advice already given there are a couple of other things to check with this motor ;
Make absolutly certain that there are no more caps on the motor backplate - FLM use tiny surface mount ones on some backplates (they are tiny little square ones).
These motors require very little lubrication so double check this.
Make sure that the locomotive runs evenly on DC (with an ammeter connected) - there may be a mechanical problem such as sticking valve gear. Also check to make sure that the wheels are even. Also check any traction tyres to make sure that they are not causing uneven running.
And lastly, the one many people often miss - the armature itself. If one of the coils look a different colour to the others or all of them show any signs of overheating replace it - it may still run OK'ish on DC but will never run well on DCC, in fact it will be worse. If you go down this route then replace the pinion from the shaft as well - this is the one that wears the most & can be diffecult to remove intact for reuse.
With a smooth mechanism & a decent decoder these "old fashioned" motors can run very, very sweetly.
Hope this helps. If you cannot obtain spares locally then send me a PM.
Please note that I have refered to the HO version here - not too sure if you have the N or HO one ?
