IL PRESSURE TRANSMITTER
This is fitted on the engine crankcase, and it is connected
to the dashboard lamp by means of electric wires; it
indicates when the pressure inside the lubrication system
is insufficient.
When the lamp on the dashboard comes on (during
running), it indicates that the pressure is below the preset
limits; under these conditions, it is necessary to stop the
vehicle immediately and check for the cause which
originated the pressure drop.
To check the transmitter efficiency, mount it on the special
tool fitted with a pressure gauge; connect the tester po-
sitive cable (+) to the transmitter and the negative cable
(-) to ground. Then blow in compressed air through the
union for the above mentioned tool, making sure that the
tester arrow moves when the pressure (looking at the
pressure gauge) reaches a value of Kg/cmq 0,15÷0,35.

NGINE OIL PRESSURE REGULATOR VALVE
The valve for the engine oil pressure regulation "A" is fitted
on the support for the cartridge oil filter: to remove it, it is
necessary to remove the oil sump.
This must be preset, in order to allow a pressure in the
delivery circuit of 3,8÷4,2 Kg/cmq.
To check its setting, it is necessary to install the valve on
a special tool fitted with a pressure gauge; blow in
compressed air through the tool union and make sure
that the valve opens exactly upon reaching the prescribed
pressure.
If the valve opens at a lower pressure, insert one or more
bottoms "B" under the spring; if the valve opens at a higher
pressure, increase the number of washers "C".
