CORK 2B7557 - Caterpillar

Assembly Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Clean the heat exchanger and inspect the heat exchanger.
Examine the heat exchanger for signs of leakage, cracks, corrosion, damaged tubes or hose connections. If the tube bundle is damaged, the tube bundle should be replaced. Check the sealing face of the end caps. If there is corrosion on the body of the heat exchanger in the area of O-ring seals, replace the body of the heat exchanger.
Clean the components of the heat exchanger in an approved cleaning fluid. Refer to the Operation and Maintenance Manual, "Overhaul Considerations" for information on the approved cleaning fluid and the proper procedure for cleaning the core of the heat exchanger.
If there is a restriction in the tubes of the tube bundle, the tubes can be cleaned with a 4.00 mm (0.157 inch) rod. Push the rod carefully in the opposite direction to the flow of sea water. Continue this operation until all of the tubes are clean.

Install the plug in end cap (4).
Insert tube bundle (2) into the body of heat exchanger (1).
Ensure that the tube bundle is centered in the body of the heat exchanger.
Apply a waterproof grease to the O-ring seals and to the grooves of the end caps. Install O-ring seals (3) on both end caps (4).
Place end cap (4) onto the body of the heat exchanger. Align mark (6) on end cap (4) with the mark on the body of heat exchanger (1).
Install bolts (5) and tighten to a torque of 7 N m (62 lb in).
Repeat Steps 9 and 10 in order to install the end cap on the reverse end. End By:
Install the heat exchanger. Refer to Disassembly and Assembly, "Heat Exchanger - Install".
