i figured out how to wire them and i uploaded a pic of what it looks like. it if fully anamated. the mats. and lighting need work but the modeling is good. (except for the motor and air cylinder)

ps. all the gears mesh correctly

pps. i never thought about 'chain' because i didn't need to make any for this anamation. however, i think i will play around trying to find an easy way to make them because it seems tricky and a good challenge for me
