Lubricating oil cooler
18.5.1 Description
A tube stack (3) is inserted in a jacket which belongs to lubricating
oil module. The tube stack is fixed at one end while the other one
is movable in a longitudinal direction to allow expansion. Both
ends are provided with two O-rings (4).
The oil flows outside the tubes, while the cooling water flows
inside the tubes through the cooler.
The tube stack is made of copper nickel and the water boxes of
cast iron.
18.5.2 General maintenance
1 Clean and test the cooler
by hydraulic pressure at in-
tervals according to chapter 04. or if the lubricating oil tem-
perature tends to rise abnormally.
2 Water side can be cleaned
by removing the cooler mod-
ule from the engine and then the lube oil cooler to clean more
carefully.
3 Always when cleaning, check for corrosion
and test by
hydraulic pressure.
It is preferable to change the tube stack too early, rather than
too late. Water leakage to lubricating oil has serious conse-
quences
18.5.3 Disassembling and assembling of cooler
a)
Disassembling
1 Open the valve (2)
for the thermostatic valve and drain
the housing. The rest of the lubricating oil in the cooler housing
can be drained from the plug (7), see Fig 18-4.
Caution!
Be careful when opening the lube oil cooler! Despite the
draining there will always be left a small amount of lube oil in
the housing.
2 Drain the water side
as much as necessary.
3 Loosen the housing fastening screws
and remove the
complete LT thermostatic valve (6) and sealing (5).
4 Remove the free O-rings (4).
