the shell at a flange connection on the top at one
end, circulates back and forth across the tubes,
and leaves the cooler at the bottom flange
connection at the other end of the cooler. During
this process Heat is removed from the oil due to
its contact with the tubes, through which the
cooling water is flowing. Baffles are provided
inside the shell to channel the oil flow in the most
efficient manner.

REMOVAL

To remove the lube oil cooler it is necessary

to drain the oil and water systems and disconnect
the piping. After removing the cooler-to-engine
cap screws, the unit may be lifted out through
the hatch opening In the roof or through the side
door.
