Then look at this, I was very preoccupied by the bearing issue too :

I did something slightly different to protect the front bearing in my Neu 1512 in a Losi 8 (and also seal the holes).

I took a piece of 1/16th aluminum plate and (using a milling machine for exact hole placement) drilled a center hole and three more for the motor screws. The center hole was reamed to a few thou clearance on the motor shaft. One of the 3 screw holes was used to hold the plate to the motor and the other two were used for the mounting screws. Almost no dirt or dust got to the bearing or front motor holes. This requires exact hole placement and sizing to keep the shaft hole centered around the shaft.
