ENGINE OIL PRESSURE ADJUSTMENT VALVE (Fig. 10-68 / 10-69 /10-70)
Check the oil pressure valve calibration.
The oil pressure adjustment valve «A» is screwed to the oil sump. It must be calibrated to allow a pressure in the
delivery circuit of 3,8÷4,2 kg/sq.cm.
To test the calibration, it is necessary to fit the valve on the appropriate tool with a gauge fitted; blow compressed
air through the tool coupling and make sure that the valve opens precisely at the set pressure.
If the valve opens at a lower pressure, place one or more «B» shims under the spring; if it opens at a higher
pressure, increase the number of «C» washers.
THERMOSTATIC VALVE (Fig.10-70/A)
The thermostatic valve opens the oil passage to the radiator when the temperature exceeds 71°c.
