This ebay Buy-It-Now offering provides a custom tune up kit and seller refurbished AT500A31 rotor for ONLY these models: Blue Point AT500, AT500A, AT500B, AT500C, AT500D and AT500E to field repair your Blue Point AT500 1/2" drive impact wrench. 

Special Service Notes:

There are several different back cover gaskets for the Blue Point AT500 series 1/2" drive impact wrench. They are all obsolete and no longer available. I have a few different gaskets that might work but I am not 100% certain of their correct application. I recommend using the old back cover gasket by carefully removing the back cover without tearing the old gasket. If you need the gasket and want to see if I have one for your tool email me some clean and decent photos of your back cover. If I have the gasket it would add $7 to the cost of one AT500 tune up kit if bought on the same ebay order. 

I also add some extra o'rings in the tune up kit not shown in the photo that I think are applicable to the product line. You will have some extra o'rings when you are done. There is one notable o'ring exception that is not provided. The o'ring for the cage as AT500-42 is not in my AT500 kit for this tool. As this o'ring is bathed in oil it typically is reused. As it do not have the sample o'ring for AT500-42 and I do not have all the back cover gaskets verified and identified in stock I am short these 2 optional items. 

The shipping weight is 1 pound with an eBay USPS.com Ground Advantage shipping label. Ground Advantage is the slowest and cheapest shipping method offered on eBay. International shipping is done by shipping to Glendale Heights, Illinois with the eBay Global Shipping Program finishing the delivery of this item.
