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
valve
clearances
should
be
set
to
0
20
mm

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

adjust
the
valve
clearances
with
the

engine
warm

to

0
25
mm
0
0098
in
for
the
inlet
valves
and
0
30

in
for

OIL
PUMP
Removal
and

Dismantling

The
rotor

type
oil

pump
is
mounted
at
the
bottom
of
the

front

timing
cover
and
driven

by
the
distributor
drive
shaft

assembly

Overhaul
of
the

pump
will

require
careful
measurement

of

the
various
clearances
to
determine
the
amount

of
wear

which

has
taken

place
If

any
part
is
found
to
be
worn
it

may
be
neces

sary
to

replace
the
entire
oil

pump
assembly
To
remove
the
oil

pump
from
the

engine
proceed
as
follows

1
Remove
the
distributor

assembly
as
described
in
the

section
IGNITION

taken
out
as
the

is

press
fitted
to
the
rotor
and
the

pin

is
caulked

Unscrew
the
threaded

plug
and
withdraw
the
regulator

valve
and

spring
Oean
each

part
thoroughly
and
examine
for

signs
of

damage
or
wear
Use
a
feeler

gauge
to
check

the
side

clearances
between
the
outer

and
inner
rotors
the
clearances

at

and
the

DESCRIPTION

Three

covered

by
this
manual
Either
a
three

a
four

be
fitted

The

three

are

equipped
with

nchromesh
on
all
forward

with
the
three

gearbox

operated
by
a

steering

and
the
four

gearbox
by
a

Two

types
of

synchromesh
are
used
in
the
four

speed

gearboxes
Either

Borg
Warner
or
Servo

types
may
be
fitted

The

gearboxes
differ

only
in
the

synchromesh
devices

whereby

the
baulk

rings
synchronize
the

coupling
sleeve
with
the
main

shaft

gear
on

is

accomplished
