How to turn multiple lines into one?

Hi,

I have a sprocket assembly that I hope to have a carrier travel around.  Up to this point I have been using a single carrier for every turn and straight section.  The sketch that I am using for mating is shown below.

What I would like to do is alter the sketch so that one carrier could be mated, and travel all the way around to check for clearances.  Any ideas?

Thanks,

Mike
