CHECK CRANKCASE (FLYWHEEL FLANGE SIDE) FOR OIL LEAKS
In the event of oil leaks from the rear part of the crankcase (flywheel area), check the following:
■ that the seal ring on the flange on the flywheel side is not damaged;
■ that there is no blowing in the crankcase. To make this check, rest the engine on a bench with the flywheel side
uppermost, after removing the flywheel from the crankshaft;
■ fill the upper part of the crankcase with water;
■ blow through the breather pipe with low pressure compressed air (to avoid dislodging the oil seals), taking care
to hold the seal ring with two fingers;
■ In presence of porosity small bubbles will be seen. In this case the porosity must be filled with a suitable
commercial compound.
OIL DELIVERY PUMP
In case of improper operation of the oil pump, check accurately the following: depth of gears should be
15.973÷16.000 mm; gear housing in pump body should be 16.032÷16.075 mm.
If not within the above sizes, the parts should be replaced.
9.985 ÷ 10.000
26.250 ÷ 26.290
15.973 ÷ 16.000
OIL PRESSURE TRANSMITTER
This is fitted on the crankcase, and is connected to the pilot light on the control panel by electric cables; its purpose
is to signal insufficient pressure in the lubrication circuit.
When the light on the control panel comes ON (with the engine running), this indicates that the pressure has fallen
below the set limits; it is necessary to stop the vehicle immediately and check the cause of the pressure drop.
CHECK OIL PRESSURE TRANSMITTER
(Fig. 10-67)
To check the efficiency of the transmitter, fit it on the
tool with a gauge fitted; connect the positive lead (+)
of the tester to the transmitter and the negative lead
(–) to earth, then blow compressed air through the
coupling of the above tool, making sure that the
indicator on the tester moves when the pressure
(looking at the gauge) reaches 0.15÷0.35 kg/sq.cm.
