Models IMPORTANT The design of the Viscount II hydraulic pump upper and lower motor housings has been updated. The cylindrical design replaces the square housing design previously used. There is no performance change associated with this update. If replacement of a square housing is necessary, both the upper and lower housings must be converted to the cylindrical design as it is not backwards compatible. -
