Restoration of a 1 Dollar Air Impact (Ingersoll Rand)

Welcome to my restoration channel. This is a restoration of an old crusted and somewhat rusted Ingersoll Rand 1/2” Pneumatic Impact. This was found and bought at an auction for around 1 dollar USD (Pretty nice find:)). We have used this for quite some time but the time came when I decide to restore it and rebuilt the impact. I purchased rebuild kit and new rubber protective boot from eBay. Before restoring, when the impact was hooked up to air it would run slowly by it self. It was also missing the the socket retainer which came in the kit and was replaced during the restoration


THE RESTORATION PROCESS
I tore the air impact apart, cleaned it and then began the restoration/rebuild. The motor housing assembly was pretty dented up and scratched from normal wear and tear. I filed and sanded (up to 1500 grit) the housing then gave it a polish. Some of the dents were deep so I did not remove them completely as seen in the restoration video. The hammer case assembly was wire wheeled and then cold blued with Perma Blue. I coated the case twice and steel wooled in between each coat then applying some oil and letting soak over night. The hammer frame and hammers were in nice shape so they only needed a good clean and regreased. I added a new o-ring and socket retainer to anvil assembly 1/2” square drive. The cylinder, motor and other parts were cleaned up then put back together with new bearings, vanes, and new retainer. Both gaskets were replaced. When disassembling the case I didn’t realize that the hammer case pilot was removable until later, I was able to remove and clean before reinstalling. A new detent spring and ball was installed in the reverse valve along with 2 new o-rings. I used pneumatic oil and a moly grease to lube the impact. Then I added the rubber protective boot to help preserve the tool in future use.

I am pretty happy with how the restore turned out and this tool will be used and not retired :)
