The liner plate includes a body portion defining an upper surface and a lower surface opposite to the upper surface. The body portion defines a first side surface and a second side surface. The body portion is adapted to be coupled to the frame surface proximate the first side surface. The body portion is adapted to be coupled to the guard member proximate the second side surface.
