A fuel tank shield is provided for mounting between a fuel tank and a
rotating drive shaft of the type having a generally smooth cylindrical
outer surface from which a hard edge extends adjacent the fuel tank
shield. A recess is provided in the fuel tank shield and a block of
cushion material is mounted in the recess to fill the recess. In an event
that would cause the rotating drive shield to encroach into the space
normally occupied by the fuel tank shield, the cushion material will be
subjected to wearing away by the contact of the hard edge of the rotating
drive shaft so that the hard edge becomes absorbed within the pocket
formed by wearing away of a portion of the cushion material.
