3 hp, oilless air compressor, Craftsman, horizontal 15 gallon tank. Unit is in good shape, except the top end is worn out. Needs a piston ring, cylinder, valve body kit, installed. I looked up the parts. Valve body is 23 bucks, connecting rod,piston, cylinder kit is 35 bucks. For less than a hundred bucks, total, and a 1/2 hour of time, you can have a very nice air compressor in your garage for tire filling, air tools, nail guns, parts cleaning, etc. I don't need this unit, Have large oiled compressors in my shop, with a couple smaller machines when I need portability. This is easy to fix, I will be happy to guide you to the parts, and assist, if you wish, to put the kit in. It is a very simple repair. A compressor similar to this, new, used to be about 280.00, retail. If you prefer, I will purchase the parts, and repair it for you to pickup, for 125.00, total. Thank you.
