T&T: Engine loss from belt driven components

[Rudy and Jill Sechez]

Our engine did not have the gear driven option, for the fresh water pump and our solution was similar to Mark's setup.
   
  We put a double belt pulley on the crankshaft, freshwater pump and the single alternator.  Our thoughts were that since all of these components could be driven with one belt, if one of the two belts broke, the other belt may continue to function.  Granted, the broken belt may instigate a scenario that sets up the second belt to also break, but then again it may not.
   
  The added advantage to double belts, they have twice the drive-friction, which would allow less tension on the belts, than a single belt might require, especially once some wear occurs.  This relieves some side loading on the bearings of the alternator, water pump and crankshaft and should prolong their life.
