HARDWARE
BOLT
HEAD
MARKINGS
Bolt
strength
classes
are
embossed
on
the
head
of
each
bolt.
Customary
(inch)
bolts
are
identifed
by
markings
two
to
grade
eight
(strongest).
The
marks
correspond
to
two
marks
less
than
the
actual
grade,
i.e.;
a
grade
seven
bolt
will
display
five
embossed
marks.
Metric
bolt
class
numbers
identify
bolts
by
their
strength
with
10.9
the
strongest.
NOTES:
1.
Use
the
torque
values
listed
below
when
specific
torque
values
are
not
available.
2.
These
torques
are
based
on
clean,
dry
threads.
Reduce
torque
by
10%
when
engine
oil
is
used.
3.
Reduce
torques
by
30%
or
more,
when
threading
capscrews
into
aluminum.

SEALANTS
&
LUBRICANTS
GASKETSJSEALANTS
Oil
based
PERMATEX
#2
and
it's
HIGH
TACK
equivalent
are
excellent
all
purpose
sealers.
They
are
effective
in
just
about
any
joint
in
contact
with
coolant,
raw
water,
oil
or
fuel.
A
light
coating
of
OIL
or
LIQUID
TEFLON
can
be
used
on
rubber
gaskets
and
O-rings.
LOCTITE
hydraulic
red
sealant
should
be
used
on
oil
adapter
hoses
and
the
oil
filter
assembly.
Coat
both
surfaces
of
the
oil
pan
gasket
with
high
temp
RED
SILICONE
sealer.
When
installing
gaskets
that
seal
around
water
(coolant)
passages,
coat
both
sides
with
WHITE
SILICONE
grease.
High-copper
ADHESIVE
SPRAYS
are
useful
for
holding
gaskets
in
position
dur-
ing
assembly.
Specialized
gasket
sealers
such
as
HYLOMAR
work
well
in
applications
requir-
ing
non-hardening
properties.
HYLOMAR
is
particlarly
effective
on
copper
cylinder-head
gaskets
as
it
resists
fuel,
oil
and
water.
Use
LIQUID
TEFLON
for
sealing
pipe
plugs
and
fillings
that
connect
coolant
passages.
Do
not
use
tape
sealants!
BOLTS
&
FASTENERS/ASSEMBLIES
Lightly
oil
head
bolts
and
other
fasteners
as
you
assemble
them.
Bolts
and
plugs
that
penetrate
the
water
jacket
should
be
sealed
with
PERMATEX
#2
or
HIGH
TACK.
When
assembling
the
flywheel,
coat
the
bolt
threads
with
LOCTITE
blue.
Anti-seize
compounds
and
thread
locking
adhesives
such
as
LOCTITE
protect
threaded
components
yet
allows
them
to
came
apart
when
necessary.
LOCTITE
offers
levels
of
locking
according
to
the
job.
LITHIUM
based
grease
is
waterproof,
ideal
for
water
pump
bearings
and
stuff-
ing
boxes.
Heavily
oil
all
sliding
and
reCiprocating
components
when
assembling.
Always
use
clean
engine
oil!
