[Question] LEGO 12V Motor Internal Materials

[Rail Co]

Hi all,

I'm a bit hesitant to ask a "stupid" question, however, I could not find the answer on my own.

I'd like to open up 2 of my 12v motors which barely run to see if I can't fix them, re-grease them, and hopefully give them new life. However, I have one question. Do we know what the internal metal blocks (A and B) are made out of? Being these were produced in 1980, and a kids toy I doubt there are any harmful metals, but I want to make sure these do not consist of any Lead or other metals as such. I know it isn't necessarily an issue to handle solid lead, but still would like to be mindful of it.

Any ideas on the material of these metal blocks?

Thanks!

*sigh* - there simply are no stupid questions! There may be stupid replies or reactions - hope the reply below makes any sense.

I recently (= two days ago) opened up one of my two (black) 12V train motors. This was one of the variety with the holes for receiving the center wheels. The motor came a couple of years ago from France along with the 7740 locomotive and carriages. Very nicely seasoned light gray slopes - I love it. I just was curious to check on its internal condition, as it was just doing fine. My 7740 is retrofitted with a PF receiver and 10 NiMH AA rechargeables, as I have a mixed 4.5V, 12V (blue and gray), RC=PF, and of course ample of powered 9V track.

As far as I can tell, the metal inside is die-cast aluminum for the two large brackets, copper/brass type alloys for the electrical contacts and worm gear, as well as the usual non-lead metals for the motor and rails contacts. You should be fine.

All the best and good luck,
Thorsten
