you're not an Ingersoll Rand customer, they only have wholesale customers, you're a Tractor Supply customer, why not go back to the tractor supply, the distributor you bought it from? .... sounds like you're taking your disappointment with yourself out on IR, and I hope you'll have lots of help next time you deal with a piece of equipment that big .... what you should ask IR is how often they're asked to replace a flywheel for that model compressor
