Abstract: A hydraulic cylinder assembly for a steering axle includes a cylinder having a piston disposed therein for selective axial movement. The piston is connected to a steering rod which extends outwardly from the ends of the cylinder. The ends of the steering rod are connected through links to respective knuckle assemblies pivotably mounted on the ends of the steering axle. Movement of the piston within the cylinder causes corresponding axial movement of the steering rod and pivoting of the knuckle assemblies to effect steering. A pair of piston stops are disposed within the cylinder at the ends thereof for limiting the axial movement of the piston. The piston stops are generally annular in shape, having one or more radially inwardly deformed portions provided therein. The deformed portions facilitate the installation of the piston stops into the cylinder during assembly. The axial lengths of the piston stops determine the desired limits for the axial movement of the piston within the cylinder.
