NOTE
While removing or installing an idler gear bearing, the bearing MUST be rotated to avoid the possibility of
damaging the bearing by brinelling the bearing races. Brinelling refers to the marking of the races by applying a
heavy load through the rollers of a non-rotating bearing in such a way that the rollers leave impressions on the
contact surfaces of the races. These impressions may not be easily discerned during normal inspection. For
example, a bearing may be brinelled if a load were applied to the inner race of the bearing assembly in order
to. force the outer race into the idler gear bore, thus transmitting the force through the bearing rollers. A
brinelled bearing may have a very short life.
