Abstract
A method of installing a snap ring, having opposed inner and outer diameters, onto an O-ring located in an annular groove of an anvil of an impact wrench includes providing a deformable base formed with an annular seat, seating the snap ring in into the annular seat, and applying the anvil of the impact wrench through the snap ring and into the deformable base applying the snap ring over the anvil and onto the O-ring located in the groove, wherein the anvil interacts with the snap ring in response to applying the anvil into and through the snap ring enlarging inner and outer diameters of the snap ring deforming the annular seat of the base allowing the snap ring to be received over the anvil and onto the O-ring located in the annular groove.
