Abstract
A wear liner installs into a bolster center bowl without the need for welding. The wear liner includes an annular wall forming an open-ring shape that defines a gap between two edges of the wall. The wear liner has one or more protrusions that extend outwardly from the annular wall. The protrusions are sized to engage with a corresponding recess in the center bowl. The wear liner is compressible by drawing the annular wall toward a closed-ring configuration so that the wear liner can be inserted into the center bowl while exerting an expansive, radially outward force. Upon expanding, and the protrusions engage with the recess or recesses in the peripheral wall of the center bowl. This engagement, along with the expansive pressure of the wear liner against the peripheral wall of the center bowl secures the wear liner in place.
