A pin assembly for use in a planetary gear including a pin including a cylindrical side wall defining a central bore that extends from a first end to a second end of the pin along its longitudinal center axis, an inlet bore, and a first annular groove that extends radially outwardly into the side wall of the pin adjacent the first end. A first cylindrical plate includes a first side wall, a second side wall, and a cylindrical outer wall extending therebetween, the first plate being disposed within the first annular groove of the pin, wherein a width of the first plate in a direction parallel to the longitudinal center axis is less than a width of the first annular groove in the direction parallel to the longitudinal center axis so that the first plate is axially slidable within the first annular groove.
