Abstract
A cushioning apparatus for a railway car includes a housing having a cylinder bore disposed therein with an end plate closing one end of the cylinder bore. A piston assembly includes a shaft extending through the end plate and a piston disposed on the shaft and slidably received within the cylinder bore. The piston is slidable between an axially innermost position furthest from the end plate and an axially outermost position closest to the end plate. A limit pin has an interference fit within a pin bore of the end plate and extends outward therefrom toward the piston for initially limiting axially outward movement of the piston short of its axially outermost position to thereby limit a length of the cushioning apparatus prior to installation of the cushioning apparatus in a railway car.
