remove the crankcase
cover and lower bear-
ing before
the
seal
can be removed.
The
seal is then pressed out of the bearing, using
an arbor press, and a new seal installed.

CENTERING
PINS
All
Johnson/Evinrude
outboard
engines
have at
least
one, and in most
cases
two,
centering
pins installed
through
the
crank-
case cover.
These pins index into matching
holes
in
the
power head
block
when
the
crankcase
cover
is installed.
These
pins
center
the
crankcase
cover
on the
power-
head block.
The centering
pins are tapered.
The pins
must be carefully
checked
to determine
how
they are to be removed
from the cover.
In
most cases
the
pin is removed
by using
a
center
punch
and tapping
the
pin towards
the
carburetor
or intake
manifold
side
of
the crankcase.
When removing a centering
pin, hold the
punch
securely
onto
the
pin
head,
then
strike
the punch a good hard forceful
blow.
DO NOT
keep beating
on the end of the pin,
because
such
action
would
round
the
pin
head until it would not be possible to drive
it out of the cover.
Centering
pins are the
first
item
to be
installed
in the
cover
when
replacing
the
crankcase
cover.

MAIN BEARING
BOLTS AND
CRANKCASE
SIDE BOLTS
The
main
bearing
bolts
are
installed
through the crankcase
cover into the power-
head
block.
Most engines
have
two bolts
installed
for the
top main bearing,
two for
the
center
main
bearing,
and two
for
the
lower main bearing.
In many cases
the upper and lower main
bearing
bolts
are
DIFFERENT
lengths.
Therefore,
take time to tag and identify
the
bol ts to ensure they will be installed
in the
same location
from which they were remov-
ed.
The
crankcase
side
bolts
are
installed
along the
edge
of the
crankcase
cover
to
secure
the
cover
to
the
cylinder
block.
