Pressing in piston
pin
(C)
Rest the whole work (piston, pin and
connecting rod with pushrod and guide)
on the tool body, bringing
the
notch
of
the guide
into
register with the
notch
provided in the
tool
body;
and
turn
the
guide by 90°, making sure
that
the small
end
is
snugly settled in the recess
of
the
body. Again, check
to
be sure
that
the
front mark on piston crown and the
identifying
mark
of
the rod are
both
on
top
side and pointing upward.
(d) Using a press and applying a force
of
anywhere between 500 and 1500
kg
(1103 and
3308
lb), push
the
pin
into
the connecting rod. Should the pin go
in
with a push
of
less
than
500 kg (1103 lb)
or
greater than 1500 kg (3308 lb), the
connecting rod
or
pin and piston must
be replaced. The guide (tool) serves to
locate the pin in the prescribed position.
After pressing the pin in,
turn
the push-
rod by 90° and take
off
the combination
from the tool body.
[NOTE]

a)
After
combining piston with connect-
ing rod, check
to
be sure
that
the pin
is
centered
on
the axis
of
connecting
rod.
If
the pin
is
found
displaced
to
one side, check the
tool
and, after
correcting it
as
necessary, use
it
to
push the pin back
to
the
center
position.
b)
As
stated
previously, restore all parts
to their original positions
in
reassem-
bly. Remember, piston and pin consti-
tute
a set and
must
not
be inter-
changed. Be sure,
too,
that
the three
pistons are
of
the same size (same
mark).

Fit
the rings
to
the piston, discriminating
the three compression rings,
as
shown, and
distributing the gaps equiangularly. The
side face
of
each ring with the
maker
and
size marks comes
on
top
side. When install-
ing the oil ring
with
expander, be sure to
position the expander tube opposite to the
gap
of
the ring.

Insert the three combinations (piston and
connecting rod)
into
the cylinders from
the gasketed surface, using a ring band on
each piston
to
embrace its rings. Make sure
that
the ring gaps are correctly distributed
and
that
the arrow mark
on
piston crown
points toward the front end
of
the
engine.
On the crankshaft side,
