I am having a problem with the harmonic balancer bolt breaking on my 465 engine. I have my salt spreader and my dump box ram belts running around my harmonic balancer. Would this put too much strain on the harmonic balancer and break the bolt? It has happened three times.

Are you using the proper strength bolt; I think it should be no less then a grade 8.
Here's a pic showing what the markings on a grade eight bolt are.
