Dave,
Motors I understand, and when youger could take most apart and put them back together without much left over. Gearboxes have always been a mystery to me and I pictured them full of little cogs and wheels like the inside of a watch.
Thanks for showing me that they are really quite simple, and your explanation was easy to follow.
Now let me guess what piece is responsible for that crunch from 4th to 3rd.
