unit
with
a

displacement

of
1
815
ce
The
aluminium

alloy
cylinder
head
has
cross
flow

ports
and
a
V

shaped
valve

layout
The

single
overhead
camshaft

is
driven
from
the
crankshaft

by
a
double
row
roller
chain
at
a

reduction

ratio
of
2
I

The
crankshaft
is
a

carbon
steel

forging
and
is

provided

with
five
main

bearings
and
four

balancing
weights
Aluminium

thrust

bearings
are
located
at

the
No

The
cast
aluminium

alloy
pistons
have
two

comp
ression

rings
and
one

Gudgeon

pins
are

fully
floating
in
the

piston
bores
and
are

equipped
with

circlips
at

each
end
to
limit

the
amount

of
their

The

forged
steel

connecting
rods

have
weight
adjusting
bosses
at

The

has
certain
additional

features

These
include
a

power
valve
mechanism
to

improve
the

performance

at

high

a
fuel

valve
which
cuts
the
fuel

supply

when
the

ignition
key
is
turned
to

and
an

idling

to

maintain
the

emissions
below

FUEL

Testing

Disconnect
the

hose
from

Connect

a
hose
with

an
inner
diameter
of
approximately
6
mm
0

in
to

the

pump
outlet
and

place
a

container
under
the
end
of

the

pipe
Note
that
the
inner

diameter
of
the

pipe
must
not
be

too

small
or

the
pipe
will
be

incapable
of

delivering
the
correct

quantity
of
fuel
when

testing
Hold
the
end
of
the
hose
above
the

level
of
the

pump
and

operate
the

pump
for
more
than
IS

seconds
to
check
the

delivery
capacity
The

capacity
should
be

U

pts
in

The

pump
must

be
removed
from
the
vehicle
if
it
does
not

operate
or
if
a

reduced

quantity
of
fuel
flows
from
the
end
of
the
hose
Remove

the
pump
from
the
vehicle
and
test
as
follows

Connect
the

pump
to
a

fully
charged
battery
If
the

pump

now

operates
and

discharges
fuel

correctly
the
fault
does
not

lie
in
the

pump
but

may
be
attributed
to

any
of
the

following

causes

Battery
voltage
drop

poor
battery
earth
loose

wiring

loose
connections
blocked
hoses
or
a

faulty
carburettor

If
the

pump
does
not

operate
and

discharge
fuel
when

connected
to
the

battery
then
the

pump
itself
is

faulty
and

must
be
checked
as
follows

First
make
sure
that
current
is

flowing
This
will
be
indica

ted

by
sparking
at

the
tenninals
If
current
flows
the
trouble
is

caused

by
a

sticking

pump
plunger
or

piston
The

pump
must

be
dismantled
in

this
case
and
the

parts
thoroughly
cleaned
in

petrol

If

the
current
does
not
flow
a
coil
or
lead
wire
is
broken

and
the

pump
must

be
renewed
A

reduced
fuel
flow
is
caused

by
a

faulty
pump
inlet
or

valve
or

The
