Tightening
Fasteners

When
tighteningthe
bolts
ornuts
that
attach
acomponent,
it

is
always
good
practice
to
tighten
the
bolts
gradually
and
evenly

to
avoid
misalignment
or
over
stressing
anyone
portion
of
the

component
.
For
components
sealed
with
gaskets,
this
method

helps
to
ensure
that
thegasket
will
seal
properly
and
complete-

ly
.

Where
there
are
severa¡
fasteners,
tighten
them
in
a
se-

quence
alternating
between
opposite
sides
of
the
component
.

such
a
sequence
for
tightening

FUNDAMENTALS
FOR
THE
DO-ITYOURSELF
OWNER

In
places
where
a
shaft
mustpass
through
a
housing,
flexible
lip
seals
areused
to
keep
the
lubricating
oil
or
grease
from
leak-

ingout
past
the
rotating
shaft
.
Seals
should
never
be
reused

once
they
have
been
removed
.
When
removing
a
seal,
be
care-
ful
not
lo
scratch
or
otherwise
damage
the
metal
surfaces
.
Even
minor
damage
to
sealing
surfaces
can
cause
sea¡
damage
and
leakage
.

The
key
to
sea¡
installation
is
to
get
the
sea¡
in
straight
without

damaging
¡t
.
Use
a
sea¡
driver
that
is
the
same
diameter
as
the
seal
housing
to
gently
and
evenly
insta¡I
into
place
.
If
a
proper
size
seal
driver
is
not
available,
a
socket
of
the
right
size
will
do
.

When
installing
a
seal,
¡t
a
good
idea
to
coat
the
sea¡
with
o¡I

to
aid
installation
.
Some
seals
are
directional
and
special
instal-
lation
instructions
apply
.
Make
sure
¡t
is
installed
with
the
lip
fac-
ing
the
correct
way
.
Normally
the
lip
faces
the
inside
.
Note
the
installation
direction
of
the
old
sea¡before
removing
¡t
.

Electrical

If
the

is

splice
in

a

Use

are
