This ebay Buy-It-Now offering provides a custom tune up kit with bearings and air inlet kit parts that will fit both Ingersoll Rand 285A AND Chicago Pneumatic 7778 1" drive impact wrenches.  The IR kit part number is 285A-TK1 while the CP kit number is 8940162816. These are not OEM parts but rather a custom blended kit designed by me to fit both applications, deliver outstanding value and results. There will be an extra throttle valve ball as I have made sure that both tools have the needed extra parts.  CP does not offer bearings in their kits while IR does.  The plunger is an extra I added to both kits. You will receive the print for both tools and the CP parts list.  

The shipping weight is 1 pound + 2 ounces with a USPS Priority Mail envelope, ebay label, tracking and insurance.  Compare my prices with other ebay sellers using 5-day S-L-O-W shipping.  International shipping is done with the eBay Global Shipping Program.
