A method of assembling a shaft assembly having a shaft defining a longitudinal axis and including a groove in an outer circumferential surface includes positioning a hub relative to the shaft and positioning a retaining ring in the groove of the shaft and adjacent to the hub. The retaining ring includes an annular body that has a first end spaced apart from a second end. The method also includes securing a retaining member to the retaining ring to constrain the first end relative to the second end.
