Step
8-
The
best way
to
seat the seal in the
transmission bore is
to
use a thick, flat
1"
wash-
er
(with
a
1-1/16"
diameter), and a
6"
length
of
1"
(inner diameter) Standard Black pipe, as'
shown
in Photo 8/9.
When
you
tap the
pipe
with
a hammer, the
washer
will
apply
equal
force
around
the face
of
the seal. This will prevent it from
going
into
the
bore
at an angle
or
caving in at the center. Now,
gently
tap the seal in
until
it is
almost
flush
with
the transmission bore.
The
little
edge
you
leave
protruding
will make
it
easier
to
remove the seal
at a later date,
if
necessary.
Please be sure
that
the seal enters the bore
straight
and
without
bending.
If
it
goes in
crook-
ed,
it
will
most
likely
tear
and lei'lk badly.
SPECIAL NOTE: In an emergency, and
if
you're
careful,
you
can also use the
tiller
wheel
to
seat
the
seal-see
Photo 8/10.
Just
slide the hub
of
the wheel
up
against
the
oil seal, and gently tap
the seal
into
place-a
handy
trick
that a
Troy-
Bilt
Owner
showed
us!
Apply
some grease
or
oil
to
the shaft and re-
place the wheel. Tap in the roll pin until it is
flush
with
the wheel hub.
Check the level
of
the
transmission gear oil.
Replace gear oil
if
the
level is below
the
oil level
plug,
which
is three inches above the wheel
shaft
on the left side. Use SAE #140
or
SAE #90
gear oil
if
available. You may use a
multivis-
cosity
#85-140
gear
oil
if
the
other
gear oils are
unattainable.

Use
1"
washer
between
pipe
and
oil
seal
(Photo 8/10) Use
wheel
to
seat
oil
seal.
PLEASE NOTE: A
properly
installed oil seal
should
give
you
long and
trouble-free
service. Please
don't
be overly
concerned
if
a
newly
in-
stalled seal leaks. It may take several hours
of
tiller
operation
for
the
seal
to
become
completely
effective.
TILLER SHAFT
OIL
LEAKS
126
Oil
might
leak
from
the
area
of
the
tiller
hous-
ing because
of
a damaged oil seal, a loose
tiller
housing
cover, loose cover
mounting
screws,
or
screws
which
had
no
sealant
put
on
their
threads.
To
replace
the
tiller
shaft oil seals, you
will have
to
remove the tines
from
your
tiller.
First remove the
tiller
hood,
as
described
on
page 136 in
this
section, then see
the
instruc-
tions
on
tine
removal on page
141
in
this
section
of
the
manual.
