FIG. A.l/7 CYLINDER HEAD TIGHTENING
SE·
QUENCE
(See
Torque Specification Table.)
CYLINDER HEAD AND GASKET INSTALLATION
Reverse
the
sequence
of
removal and take good
note
of
the
followina:
1.
Thoroughly clean
both
crankcase and cylin-
der head mating planes
to
remove gasket
particles
which
have remained
stuck
to
the
surfaces at removal.
2.
Do
not
apply any sealing compound
to
the
gasket, as
its
surfaces have already been
treated
with
a
suitable
adhesive compound
over the areas requiring the greatest sealing
performance:
this
will
adhere
to
the crank-
case and
cylinder
head surfaces under the
effect
of
heat as
the
engine reaches
operating temperature.
3.
Place
the
cylinder
head
with
the
crankcase
locating
dowel
fitting
in the head hole.
4.
Install the capscrews and torque them
following
the sequence illustrated in Fig.
A.l/7 and
to
the
values given in the
"Torque
Specifications"
table.
ENGINE OIL SUMP
To remove the
oil
sump
only
from a
tractor
in·
stalled engine, proceed as
follows:
1.
Drain
oil
through plug
hole
at
bottom
of
sump.
2.
Disconnect the hydraulic
lift
delivery and
return
oil
lines.
3.
Remove the
front
axle assembly as outlined
on page 108 in Power Train Section.
4.
Back
out
the capscrews attaching the oil
sump
to
the crankcase. Before removing
them, place a wooden
block
under the sump
to
support
it
once free.
The operation
is
easier
if
the engine is installed
on a turnover stand, as
it
will
be
sufficient
to free
the
pump
to
remove the attaching screws
to
the
crankcase.
As
to
cleaning and checking, see the
outline
reported in the preceeding
topic
and referring
to
the crankcase.
When installing the oil sump, be sure to:
1.
Apply
a
thin
coating
of
non-hardening
sealing
compound
on
both
surfaces. Install
the
end seals over
the
gaskets and make sure
the
holes are aligned.
2.
Place the
sump
and
install
all attaching
capscrews.
3.
Make sure the
oil
sump and engine bell hous-
ing
are flush
with
each other.
4.
Cross
tighten
progressively
to
the
torque
values in
the
"Torque
Specifications"
table.
