    Patent number: 6367141
    Abstract: A method of inserting a piston assembly into a cylinder of an engine block. The method eliminates the need for a technician to individually lift and insert the piston assemblies into the respective cylinders. The method for inserting the piston assembly into the cylinder aligns the piston assembly with the cylinder and inserts the piston assembly into the cylinder by pivoting the piston assembly from an upright position to a horizontal position, and inserting the piston assembly into the cylinder of the engine block.
