Fixture assembly for pressure disk locating dowel on engine flywheel

The utility model provides a tool assembly for a pressure plate positioning pin assembly on an engine flywheel. The tool assembly is composed of a flywheel cushion block and a pressure plate positioning pin assembly tool; a circle of lug boss is embedded into an annular flute on an axle hole edge of the flywheel and arranged in the center of the flywheel cushion block; the pressure plate positioning pin assembly tool is columnar; and a positioning hole matched with the positioning pin is formed at the lower upper of the pressure plate positioning pin assembly tool. When in use, the flywheel cushion block is used for fixing the position of the flywheel, preventing the flywheel from transverse displacement and longitudinal displacement when the pin is assembled, and further uniforming deformation. At the same time, the positioning pin assembly tool is utilized to knock the positioning pin into the pin hole of the flywheel and can accurately control the assembly depth of the positioning pin, further control the
