Universal professional tool set for mounting valve springs with 16-30mm outer diameter.
Changing valves or valve stem seals always requires removal of the valve springs. Due to the special wedge clamping of the spring retainer, assembly is almost impossible without this special tool. This tool allows a quick, professional and absolutely simple disassembly and assembly of these components. An absolute must for workshops and hobbyists who often deal with 4-stroke technology.AI-translation
