on the
outer
metal
of
the seal
and drive it
into
the bore
of
the
tiller
housing.
Be very careful
to
never
allow
the rubber to
touch
the
tiller
shaft
around
the keyway, since
the slightest sharp edge could
cut
it
and cause
it
to
leak.
You can
gently
tap the right seal on the
tiller
shaft
into
the
housing
bore
with
a small piece
of
1
W'
pipe.
If
the pipe
is
threaded on one end,
so much the better.
Just
put
a cap on it and it
will give you a surface
to
tap on more
firmly
and
squarely-see
Photo 8/20. Otherwise, tapping
the seal
into
place
with
two
hammers-one
on
each side
of
the
seal-is
a method
that
works
out
quite
well. As
you
tap with a 1
W'
pipe,
work
the pipe to the outside edges
of
the seal.
Alternate from one outside edge
to
another.
This will prevent the pipe
from
centering on
the seal and caving
it
inward.

fit, you should make
your
check
while
the bear-
ing
cup
(part #9402) is installed in the cover,
but
before the seal has been installed.
This
way,
you can determine
how
well the cover fits.
To
replace the seal
on
the left side, you mere-
ly
turn
the

cover
back
over (with
its outside facing up) on
the
blocks
of
wood
and use the 1
W'
pipe cap,
or
another
block
of
wood. to tap the seal in place,
gently
and evenly.
Or, if you wish, you can tap the seal on the shaft
with the 1
W'
pipe after the
cover
has been fas-
tened in
place-see
Photo
8/21. (Please read
further
for
instructions
on
replacing the
tiller
housing cover.) Remember
to
put a gasket seal-
er (like Permatex) around the
outside
of
the seal
before installing on either side
of
the transmis-
sion. Drive the seal in until it
is
nearly flush
with the casting. Don't center the
1112"
pipe
as
you drive the
seal
in. Keep moving
It
from one
outside edge of the seal
to
another. This is to
prevent the seal from caving in at the center
and peeling the seal's metal back as you drive
it in the housing.
