VALVE
CLEARANCES

Adjusting

Incorrect
valve
clearance
will
affect
the

performance
of

the

engine
and

may
damage
the
valves
and
valve
seats
Insuf

ficient
valve
clearance
will
result
in
loss
of

power
and

may

prevent
the
valve
from

seating
properly
Excessive
clearance

causes
the
valve
to
seat
and
reduces
the
amount
of

valve
lift

This
will
result
in

noisy
operation
with

damage
to
the
valves

and
seats

Adjustment
is
made
with
the

engine
switched
off

and
should
be
carried
out

initially
with
the

engine
cold
to

allow
the

engine
to
run
Final

adjustments
are
made
after

wanning

up
the

engine
to

its
Donnal

operating
temperature
The

engine
can
be
rotated

by
removing
the

sparking
plugs
to
release

the

cylinder
compressions
then

selecting

top
gear
and

pushing

the
vehicle
backwards
and
forwards

The
cold

clearances
should
be
set
to
0

0
0079
in
for
the
inlet
valves
and
0
25
mm
0
0098
in
for

the
exhaust
valves
Check
the
clearance
between
the
valve
and

rocker

using
a
feeler

gauge
as
shown
in

Fig
A
40
Slacken
the

locknut
and
turn
the
adjusting
screw
until
the

specified
clearance

is
obtained
then

tighten
the
locknut
and
recheck
the
clearance

The
feeler

gauge
should

just
be
free
to
move
between
the
rocker

and
valve
When
the
cold
valve
clearances
have
been
set
run
the

engine
until
it
reaches
its
normal

operating
temperature
then

switch
off
and

Assembly
is
a
reversal
of
the

dismantling
procedure
Before

installing
the

it
will
be

necessary
to

rotate

the

engine
until
the

and

align
the

punch

mark
on
the

spindle
with
the
hole
in
the
oil

as
shown

in

Fig

1000

km
600
miles
the

should
be

changed
regularly
at
5000
km

3000
miles
intervals

Draining
is
more

easily
accomplished
after
a

lengthy
run

when
the
oil

being
thoroughly
warm
will
flow

quite
freely

Stand

operates
smoothly

COLLAPSIBLE
STEERING

The

collapsible
steering
column
is

designed
so
that

compression
occurs
when
the
vehicle
is
involved
in
a

head
on

collision
See

Fig
K
13

Two
forces
can
be
considered
when
a
collision
of
this

type
takes

place
These

being
the

primary
force
in
which
the

forward
motion
of
the
car
is

suddenly
halted
and
the

secondary

force

as
the
driver
continues
in

a
forward
direction
onto
the

steering
wheel

and
column
The

collapsible
column
is

designed

so
that
it
does
not
move
to
the
rear
i
e
into
the

driving
com

partment
when

the

primary
force
or
forward

motion
of
the
car

is

suddenly
halted
When
the

secondary
force
takes

place
as

the
driver
is
thrown
forward

the
column

jacket
gradually

collapses
and

partially
absorbs
the
amount
of

impact

The

collapsible

type
of
column
is
no
more

susceptible
to

damage
than
an

ordinary
column
when
it

is
installed
in
the

vehicle
however
when
a

collapsible
column

is
removed
it
must

be

carefully
handled
A

sharp
blow
on
the
end
of
the
shaft
or

gear
change
levers

dropping
or

leaning
on

the

assembly
can

cause

the
column

jacket
to
bend

particularly
at
the
bellows

part
which
absorbs
the
shock

The

steering
movement
is
transmitted

by
the

lower
shaft

and

upper
tube
The
lower
shaft
exterior
and

upper
tube

interior
are

tightly
fitted

together
with
four

plastic

pins
com

pletely

eliminating

any
gap

When
a
collision
occurs
the

plastic
pins
shear

and
the
lower

shaft
enters

the

upper
tube
this
action
will
cause
the
shaft
end

to

spread
and
the
lower
shaft
cannot

then
be
withdrawn
unless

an

extremely
high
load
is

applied

The
shaft
is

prevented
from

moving
towards
the
drivers

compartment
when
the

primary
force

takes

place
i

e
when

the
forward
motion
of
the
vehicle
is

suddenly
halted

by
the

three

stoppers
on

the

jacket
tube
The

steering
lock
collar

mounted
to
the
shaft
contacts

the
stoppers
and

prevents
a
rear

ward
movement

A
part
of

the

jacket
tube
is

specially
formed
to
act
as
an

energy
absorbing

part
of
the

collapsible

steering
The

upper

and
lower

guide
tubes

joined
with

polyacetal
resin
are

inserted

into
the
mesh
tube
so
that

energy
generated
by
a

collision
can

be
absorbed
as

smoothly
as

possible
with
a

low
load

The

steering
column

clamp
shown
in

Fig
K
14
is
secured

to

the

jacket
tube
and

body
by
bolts
with
two
aluminium

slidings
blocks
set
to
the

body
by
plastic
pins
An

impact
from

the
drivers
side
causes

the

plastic
pins
to
shear

and
leave
the

sliding
block
in
the
column

clamp
side

allowing
the

clamp
to

move
with
the

jacket
as
it

collapses
