INTRODUCTION

The
1400
1600
cc

and
1800
cc

engines
are
four

cylinder

in
line
units
with
a

single
overhead
camshaft

and

fully
balanced

five

bearing
crankshaft

The
valves
are

operated
through
rockers

which
are

directly
activated

by
the

earn
mechanism

The
crankshaft
is
a

special
steel

forging
with
the
centre

main

bearing

equipped
with
thrust
washers

to
take

up
the
end

thrust

of
the
crankshaft
The

special
aluminium

pistons
are
of

the
strut

construction
to

control
thermal

expansion
and

have

two

compression
rings
and
one
combined
oil

ring

The

gudgeon
pins
have

special
hollow
steel
shafts

and
are

a

fully
floating
fit
in

the

pistons
and
a

press
fit

in
the

connecting

rods

The
aluminium

alloy
cylinder
head
contains

wedge
type

combustion
chambers

and
is
fitted
with
aluminium

bronze
valve

seats

for
the
intake
valves

and
heat
resistant
steel
valve
seats

for
the
exhaust

valves

The
cast

iron
camshaft
is
driven

by
a
double
row
roller

chain
from
the
crankshaft

pulley

The

engine
is

pressure
lubricated

by
a
rotor

type
oil

pump

which
draws
oil

through
an

oil
strainer
into
the

pump
housing

and
then
forces

it

through
a
full
flow

oil
filter

into
the
main

brakes
for
the
front

All
brakes
are

hydraulically
operated
from
the
brake

pedal

with
the
rear
brakes

additionally
operated

by
a
mechanical

handbrake
and

system
Either
a

single

master

cylinder
can
be
fitted
The
tandem
master

cylinder

provides
a
dual

braking
circuit
in
which
the
front

rear

brakes
are

separately
supplied
If
ODe
circuit
fails
the
other

circuit
will

still

operate
and
provide
a
reduced
but
efficient

braking
action

The
brake

pipes
are

double
wall
steel
tubes
and
are

galvanized
at
the
sections
beneath
the

floor
to

prevent

corrosion
