FIG
1 :17 Installing
the oil
pump.
The
oil
pump
drive
gear
must be
positioned
so that
the slot
is in line
with
the threaded
hole of No. 12 cylinder head
bolt
cylinder block to uncover the
pump
fixing screw. Remove
this screw and lift
out the
oil
pump.
To reÍit
the oil
pump
and
get
correct oÍientation oÍ the
distributor,
rotate
the engine to bring number 4 cylinder
piston
to TDC, Install
the
oil
pump
so that the distributor
drive slot in the spindle
points
to
No. 12
cylinder head
stud with
rhe large
oÍÍset oÍ the drive towards
the
engine
(see
FIG 1 :17). ReÍit

Íixing screw and
cap nut.
Using a new cork
gasket
refit
the sump.
1 :9 Removing
the
clutch and
Ílywheel
The removal
of the clutch and flywheel
with the engine
in
the car necessitates
the
removal
of the rear axle in
order
to
first remove
the
gearbox.
This
operation is
detailed in
Section 5:4.
With the
gearbox
removed, mark
the
clutch
plate
in
relation to the
flywheel in order
to
facilitate correct
reassembly.
Slacken each of
the
six
retaining bolts
approximately one turn
at a time, working diagonally
acÍoss the
clutch,
until
all the
pressure
has been
removed
from
the diaphragm spring.
Remove the six bolts attaching the
flywheel to the
crankshaft and remove the Ílvwheel.
The ilvwheel
and
crankshaft
bear location marks
which
must be lined up
when reassembling.
After
prolonged
slipping and
wear
of the clutch
linings, the bottom
of
the flywheel
(see
FIG 1 :18),
may
be
found to
be scored. lÍ this has happened, it
will be
necessary to true
up
this
surÍace on a lathe. The
same
thickness
oÍ metal
removed
must then be
removed
from
the
face
on which the
clutch
mechanism
rests, so
as
not
to alter the spring tension.
Two
types
of
flywheel
are
in
service.
On earlier models
the
depth
P is
25.9mm and
on
later
installations
the
depth
is 25.5mm.
This oÍ
course means that there
are
also two
types of driven disc
and the discs are
not
interchangeable.
Flywheels
are interchangeable
pro-
vided
that the
appropriate driven
disc
is
used.
Refitting:
Ensure that
the mounting
face
of the Ílywheel and
the
crankshaft flange
are clean and free from
burrs.
Line
up
the
location
marks and
press
the
Ílywheel into
position.

Fit the retaining
bolts and tighten them to
a torque of
44
ro
47
lb Íï.
Place
the clutch disc
in
position
on
the flywheel
with
the location
marks aligned. Fit the retaining
bolts and
tighten
to a torque oÍ
11 to 18 lb ft, having
centred the
driven
plate
with a spare
gearbox
shaft or a suitable
mandrel.

Remove the cvlinder head as detailed
in
Section 1 :4.
2 Drain
the oil and
remove the sump.
3 Unscrew the big-end bolts a few turns
(see
