So ever since I was I kid I always take apart any old toys, printers ect I could get my hands on. Then I would try and find the area where all the gears and motors were and throw out everything else. So what I want to know is any one able to open up some Lego motors to see how they work and post them here? I want to see some internals.

9v system

Does this help at all?

Thanks philo I was the one who asked about the 4.5 v motor

Was a buggy motor hard to take apart and reassembled? Because I've got one that is doing some weird sounds but it works... for now.

If I can fix it that would be awesome.

I'm an expert when it comes to fixing things

It's a bit difficult to disassemble without leaving any scars, but otherwise it's relatively easy.

The small black lid has four clips that need to be pried out. No need to open gears case if it's an electrical problem - here it was a broken wire (yellow top right component, a resettable fuse)

philo what is the ratio of that gear train?

Any idea what's my problem by checking the video?

Sounds really bad, I'd personally give it a go at taking it apart, it sounds like something's out of place and hitting other bits around and it won't live long :(

Does it sound the same if you in reverse mode? and are both red part turning, or is one blocked ?
