Illustration 5 g06014758Note: Type 1 heat exchangerNote: Do not use the old gasket.Note: Heat Exchanger Plate (Y) and Heat Exchanger Plate (Z) are identical. The orientation of the dimple (one dimple) on the heat exchanger plate is critical during the assembly of the heat exchanger plates. Heat Exchanger Plate (Y) and Heat Exchanger Plate (Z) are for the jacket water in the heat exchanger.Note: Heat Exchanger Plate (X) has notches that are stamped in the heat exchanger plate. The notches identify the ports that are blocked to prevent coolant flow. Heat Exchanger Plate (X) is installed against the front frame.Position the flat side of the seal against the frame assembly.
