RV Repair: repairng belts on 83 allegro camper, crank pulley, 460 ford

Question
I am attempting to replace the belts on my 83 allgro camper and there is no diagram on how they are to go.  The belts originally popped so I do not know how they were.  Can you help?

Answer
How did they all pop?  Bent pulley?  

I have a pic for a one serpentine.  None for your application.  

You will have 2 or 3 usually.  If you look from the side of the motor you can see which groves line up with eachother.  One of the pulleys will be adjustable (power steering, alternator, etc).  Look at the crank pulley and see how many grooves look like they are clean.  That is how many belts you need.  If you buy the correct belts, you should be able to match them up.  Wish I could be more help.  

What motor do you have?  Maybe you can look for the motor in another vehicle and find the diagram easier (ie. 454 chevy, 460 ford, etc).
