Piston Ring Expander -- TS-313
This is a slick little tool for spreading the piston ring to easily slip it over the piston. If you only repair one engine in your life you might do without this tool, but it's a nice convenience for a small price in the $7 to $15 range. Spreading the rings with your fingers could result in a few bloody finger tips. Worse yet, one broken piston ring might put you out of business, as there are never any spare parts in a set of piston rings.
