I just had a problem with the main pulley on my crank coming loose. It caused a wobble that tore up a set of belts and caused another to keep falling off before I had it fixed. The fix is only temporary as the threads were beginning to strip so soon I will need to replace the crank and while I am at it have the engine rebuilt. Check to make sure its not that, as letting it go will cause some damage.
