Thermostatic valve
18.6.1 Description
The Fig 18-5 shows the valve in a closed position (left). When the
temperature exceeds the nominal value, the contents of the elements
(1) expands and forces the valve unit (2) towards the end flange, thus
passing part of the oil through the cooler. This movement continues
until the right temperature of the mixed oil is obtained. As the cooler
becomes dirtier, the temperature will rise a few degrees, which is
quite normal, because the valve needs a certain temperature rise for
a certain opening to increase the oil flow through the cooler.
Thermostatic valve for oil system
18.6.2 Maintenance
Normally, no service is required. Too low an oil temperature
depends on a defective thermostat, too high a temperature may
depend on a defective thermostat, leaking O-rings, although, in
most cases, it depends on a dirty cooler.
1 Drain as much cooling water
as necessary to empty the
valve.
2 Remove the lube oil thermostat housing end flange (3).
3 Remove the thermostatic element holder
by opening
the screws and withdraw the elements. Use extractor tools
800122 and 800029 for element holder if necessary.
