The crankshaft damper includes a cover plate removably coupled to the housing. The housing and the cover plate enclose an annular chamber therebetween. The crankshaft damper further includes an inertia member disposed within the annular chamber. The cover plate includes an outer diameter surface located at an outer diameter thereof. The outer diameter surface defines an annular outer edge. The crankshaft damper further includes a plurality of outer through-holes formed as notches on the annular outer edge of the cover plate. Each of the plurality of outer through-holes extends inward along the outer diameter of the cover plate. Further, each of the plurality of outer through-holes receives a fastener therein to couple the cover plate to the housing.
