Begin the installation by seating the replacement retainer flush against the bearing assembly. Next, place the thin rubber gasket in the recess and set the ceramic insert atop the gasket. Note that the ceramic has a top side and bottom side; the bottom is identified with slightly recessed grooves. These grooves should face downward toward the rubber gasket.

Before proceeding, place the shaft end on a wooden block; the wooden block should push the shaft to its forward-most position (there should not be any end-play in the shaft).
