LEGO 12V Train Motors

[bricks n bolts]

To lubricate it without opening it, I squirted a bunch of WD-40 into that motor (there are a couple of openings, e.g. for the middle wheels), and then carefully shook the motor for a while, in various directions, to make sure it gets everywhere (without opening it, that's really the only way I can get it to reach the spots that I want to reach).

It's quite easy to tell if all the spots that I want to reach have been reached: A good motor should move with as little as 2 volts (of course, the speed at 2 volts is very low). Before I lubricated this motor, it would not turn even at 4 volts, to get it to turn its wheels it needed at least 5 volts. After I lubricated it, it now moves at 2 volts (and it runs more quietly), even at 1.5 volts the wheels already start to turn. That means that everything that needs lubrication has received some.

Thanks hoeij, I must give this a try on some of mine which have those symptoms.

Whilst looking through some of the LugPol posts/ links I stumbled upon this method of replacing pickups on the 12v motors.

There is no explanation but you get a rough idea from the pictures.
