Review on 🔧 DAC-308 Piston Ring: An Essential Replacement for Craftsman Air Compressor Models K-0650, K-0058, KK-4835, KK-5081, A02743 by Jae Newton

There is no need to buy a complete set of pistons with sleeve. I sanded the bushing with 2000 grit sandpaper and then sanded it. It didn't have any real grooves at first, but I just did it out of caution. The seal is flat. You need to center the gasket and tighten the T25 torx. Simply hold them centered and tighten until the gasket flexes and the screw is tight. I also needed the exhaust and intake valves, so I replaced the entire plate. I have a craftsman 919165330 6.5 hp. 33hp 240v, it's a big twin engine hot dog. I used my Dewalt impact wrench in 1st gear which comes out to about 25 pounds.
