Removing
timing
gears
(15)
Remove timing gears and
detach
the
front
plate from cylinder block.
(16) The push rods, tappets and
speedometer
driven
unit
having all been removed, draw
out
the engine camshaft.
(17)
Open the big end
of
each connecting rod
by removing
the
cap. Push
out
each piston
assembly from block top.
[NOTE]
Have all removed parts laid
out
in
groups, identifying each
part
for the
cylinder from which
it
was taken.
It
is
a
standard practice to assign a reference
number
to
each cylinder and use
that
number
to
refer to the group
of
parts,
whIch
of
course include bearing shells,
piston rings, etc. Never drive
out
the
combination
of
piston and connecting
rod: push on the mating face
of
big end
with a wooden stick,
as
necessary,
not
to
damage the bearing shell.

Use
the
piston pin setting tool (special tool)
to
separate piston pin from piston in the
manner illustrated here: lay down the
connecting rod
on
the tool
body,
fit the
pushrod tool
to
the
piston pin in place,
and press down the pushrod
to
force the
pin out. Never use a
hammer
to drive
on
the
pushrod
tool.
Removing piston pin
[NOTE]
a)
Never drive
off
the pin.
If
the pin
is
seized in the piston, it may be neces-
sary
to
replace, piston, pin and con-
necting rod with new ones.
b) Do
not
apply a press force
of
more
than
3000
kg (6615 Ib)
to
the special
tool.
(19)
Remove the main bearing caps. Set aside
the removed caps and bearings separately
in
groups, each marked for its journal, so
that
the same combination
as
before can be
reproduced at the time
of
reassembling.
Before removing caps, read the crankshaft
end play and write the reading down for
reference.
(20) Take
off
the crankshaft.
INSPECTION
Cylinder head
(1)
Wash
the
cylinder head clean. Before doing
so, visually examine
it
for evidence
of
cracking, water leakage
or
any damage.
