Review on DASBET 5pc Blind Hole Pilot Bearing Gear Puller: Efficient Slide Hammer Removal Tool by David Alexander

You get what you pay for. This is a cheap tool. It wouldn't work at all due to the lack of raised grip material on the fingertips. You insert a tool and tighten the center screw to expand the pins in the center of the pilot bearing. The outside edge of the pins has a small protrusion designed to grip the inside top edge of the pilot bearing so it can be hammered out. The protrusion is not pronounced enough to be hooked, so the tool is pulled out without removing the guide bearing.
