Kinda hard to solder plastic, but we can try anything once.

Actually............. I had an eccentric crank, made of Delrin, that had been broken, when someone picked up the loco, with a little too much....gusto? yeah that'll work.
Even the glue that was supposed to hold Delrin, wouldn't hold, so, I took a bit of Delrin sprue, and used it to "solder" the two pieces of the crank back together.
The repair has lasted for about three years now.

In model railroading the old boyscout moto works everytime.
No not always be prepared. IIIIIMMMMPPPRRROOOOVVVVIIIISSSEEEE.
