Ertl John Deere electric engine

[Meco3hp]

Hello,
I pick one of these up at a auction the other day. It's the one with a electric motor inside with a poor sounding recording of a engine running, when you turn it on. The O-ring that runs the flywheels is in small chunks from old age. I want to put a new o-ring on and get it back up and running.(mechanical restoration) How do you do this with out tearing the motor completely apart? My one thought is to split the o-ring and thread it in and then splice it back together. The thing I'm worried about is getting the drive motor apart and back together without breaking anything, if I decide not to go the spliced way.

Any ideas?

Thanks!

I have seen an O ring splicing kit for making custom sized rings. I'm sure however, that they are not cheap. In a pinch I have seen guys use superglue, or locktite 404 to splice them, but generally only under compression, doubt it would work with a pulling load.

Superglue works great to splice o-rings. Cut the ring with a razor blade and use fresh superglue. I repair dial drive belts in old Zenith radios this way.
