Secondary steering motor (1) is a 24 Volt DC motor. Motor (1) drives secondary steering pump (3). Motor (1) turns pump (3) in a counterclockwise direction.Secondary steering pump (3) is a gear pump. Gear pump (3) pulls oil in inlet port (2). The oil is pulled around the gears. The oil exits through outlet port (6). The oil travels through a check valve.
