OIL PUMP
Remove the oil sump (refer
to
instructions
on
page
15),
the pump
mounting
capscrews (Item
Cs, Fig. A.lll/1) and, finally, the oil pump.
After disassembling the pump (Fig. A.V/1) in-
spect and measure components versus the
values reported in the table
of
data.
At assembly, note
of
the
following
points:
1.
The pump body comes fitted
with
the shaft
(Item
5)
of
the driven gear (Item
3),
which is a
shrink
fit
on the shaft.
2.
Make sure the torque
specification
is
met
when
tightening
the capscrews which secure
the pump
to
the crankcase at rear
of
this

FIG. A.V/2 DISASSEMBLY (REASSEMBLY) OF
OIL FILTER
OIL FILTER
The
oil
filter
is furnished complete with the con-
tainer, which comprises the cartridge and
its
outer seal and is screwed
to
the crankcase.
Replace the
filter
at every oil change, therefore
after every 120 working hours,
to
avoid clogging.
If
the
filter
gets clogged, the by-pass valve (set at
12.8-15.6 P.S.I.
or
88.3-107.6
kPa)
automatically
. by-passes the filter,
thus
allowing the lubricating
oil
to
reach the engine anyway but in
this
case
the by-passed
oil
would be unfiltered.
The
filter
can be removed by simply unscrewing
it
by hand from
its
support (Fig. A.V/2).
The
filter
is
of
the full-flow type, consequently ef·
ficient
performance is a must. It
must
therefore
be regularly replaced at the specified intervals,
as the integral body construction offers no
possibility
of
checking or replacing components.

bulb
lamp which goes on in the following cases:
