I have a Specrum series N Scale Doodlebug that was attacked by a grandchild! Is there somewhere I can get an exploded view of how the linkage goes together? I don't seem to have the original paperwork.  I am having difficulty figuring out if something got broken or not in the linkage. There is a single offset nylon pin in the brass connector from the motor to the linkage. When put the nylon linkage into the brass hole with the nylon pin, it just pops out again.

Anyone?

Thanks,

Poppy
