If it is the same as the C65 that we use to have there should be two adjusters per wheel. They essentially are as you describe an eccentric or cam that you adjust to keep the shoe closer to the drum. Basically you just turn on the stud to move the cam. It is easier if you jack up the wheel you are adjusting so you can tell what you are doing. I can't remember which way to turn to tighten it up. You will have to experiment.
