Clever way of doing that...CAT has a special tool for everything

I made all my tools years ago, I welded a 9/16 “ fine thread bolt to a 5/8 nut screwed it on a 5/8” all thread approx 10” long made a weight approx 2 lbs slid it onto the all thread nut on top a slide hammer works way better still use it today

Good work bro👍
