Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g01164559
Install rubber seal (10) and titanium collar (11) in the rear frame.
Install Tooling (A) .
Illustration 2 g01164599
Position new gasket (9) on plates (8) . Install the tabs of the gasket into the slots of the plate.Note: Do not use the old gasket.Note: The gasket on the plate assemblies should face the engine during assembly.Note: The Gasket for Heat Exchanger Plate (Y) and the Gasket for Heat Exchanger Plate (Z) are identical. The orientation of the heat exchanger plates is critical during the assembly of the heat exchanger plates. Heat Exchanger Plate (Y) and Heat Exchanger Plate (Z) are for the sea water in the heat exchanger.Note: Heat Exchanger Plate (M) identifies the ports that are blocked in order to prevent coolant flow. Heat Exchanger Plate (M) is installed against the front frame. The orientation of the heat exchanger plate is critical during the assembly of the heat exchanger plates. Heat Exchanger Plate (M) is for the jacket water in the heat exchanger.Note: Heat Exchanger Plate (W) does not block any of the ports in order to prevent coolant flow. Heat Exchanger Plate (W) is installed against the engine. The orientation of the heat exchanger plate is critical during the assembly of the heat exchanger plates.Note: Heat Exchanger Plate (X) does not block any of the ports in order to prevent coolant flow. The orientation of the heat exchanger plate is critical during the assembly of the heat exchanger plates. Heat Exchanger Plate (X) is for the jacket water in the heat exchanger.
Install plates (8) on the heat exchanger.

When plates (8) are installed correctly, the edges of the plates will form a honeycomb pattern.

Position front frame (6) on Tooling (A) . Install bolts (7) in front frame (6) and hand tighten the bolts. Tighten the bolts in the numerical sequence that is shown in at least three incremental steps until the front frame is tight against the spacers. Tighten the bolts in equal steps so plates will not bend. The plates for the heat exchanger will compress approximately 30 percent when the bolts for the frame are tightened.
Remove Tooling (A) .
Illustration 6 g01164548
Install bracket (3) and bolts (2) .
Install spacers (4) . Install middle bolts (5) on each side of the heat exchanger.
Illustration 7 g00777238
Install the spacers and bolts (1) .
Refill the cooling system with coolant. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change".
