I've serviced several MD roadbooks before, so I might be able to give you a hand...
The belt drives are standard seal rings. They can be bought at any general hardware store. Just remove them, and take them with you to the store and find ones a tad smaller in circumference (better smaller than bigger!).
Which roller bars were you exactly referring to? The ones which have turning knobs on the left-hand side of the RB? Or the one on the very top where to paper slides over? Or the motor driven one?
What you might also want to do is:
- Take apart the motor, clean it from dirt and sand, and grease it up again
- Roughen up the motor driven roll with the help of a lathe, as these tend to lose grip over time
What you must remember is, that the 2 knobs have 2 different threads!!!! The bottom one is a standard right-turn-to-tighten thread. Top one a left-turn-to-tighten!!!
