Im wondering if some tech-heads could help with the repair / replacement of a 12V motor from a red train motor? When I received the motor the previous owner indicated that there was a 'clicking sound' from inside. Careful dis-assembly (following the 12V Motor thread) allowed me to get a first glimpse inside; and showed that there was clearly a problem with the commutator (?)

The pickup plates are still connected to the transformer wires, but the soldering has fractured. There does not appear to be any burning through of the motor - just a mechanical failure.

Lego 12V Motor Normal by roamingstudio, on Flickr The question is whether anyone thinks this is really repairable (I have a decent SMD soldering iron etc; and could try to fix it with time and patience) or should I try to find another 12V motor which could replace it (does anyone know of a suitable replacement; other than another defect 12V motor). If I have to give up on the motor - would it make sense to try and fit a modern PF motor inside the red chassis? Thanks for any thoughts and tips.
