Opening up a 9volt train motor

[Captain Green Hair]

Hey folks,

It appears i killed one of my 9V train engines and now i'm trying to open it to see what is wrong.

I can't get it open for some reason, so maybe somebody has some advice on this?

Thanks in advance!

Well, heres a picture of a disassembled motor, thanks to Legomatic

And here's a picture of the Motor carriage with the bottom removed

Hopes this helped a bit.

Only to get a trainmotor open, is difficult. You've to break it open with force on the right places. And when the elec motor itself is broken, you've to replace it. Only where to get those....... I think it's beter to buy a new one.

Well it moves a bit and then stops, it could also be a problem with the gears.

Do you know where to apply the force to open it?

I tried, but it didn't work...

Thanks so far guys!

I am afraid the only way to do it is to cut the small thingies that hold it in place... but they are quite resistant, so make sure you don't cut your finger as well (learn from others' mistakes *cough*, not your own!). Here is a nice picture-guide, just ignore the DCC part ;)

I was confused with 12v motors, those are glued. The 9v motors are clicked together. Just use a knife to break the clips, they you should be able to open it. When you remove a little coin somewhere, the motor should run smoothly again. I've once done that for another person, who had exactly the same problem.

To glue it together, I suggest to use paperglue. In case you have to open it again.

Thank you all, i now know how to do it.

It's a strange problem, the engine runs fine at the moment, but after a short period it suddenly stops..

Has anyone had a similar problem?

Has anyone had a similar problem?

I had something similar some time ago, though it had nothing to do with the motor itself but with the wire leading from the net-current to the transformer, the worn wire got a loose contact from time to time bringing my railwaybusiness to a non-scheduled stop...

But I assume you checked everything else to make sure the problem lies with the engine and not with anything else?

Yes, my other engines run wonderful.....

Yes I have the exact same problem, I just bought it so I'm going to phone LEGO for a new one.

Update: I just got a new one from LEGO in the mail. I only bought mine a month ago so I'm glad tey replaced it. They didn't want the broken one back. So Now I have something to do some tests on :)

Great, let me know how it goes!

I think the thermal sensor is the problem, but i could be wrong...
