it is
wet
with
oil
there,
don't
worry
about
the
oil
seal in the bearing cap.
The
tiller
was designed
to relieve a little excess oil pressure there in
cer-
tain circumstances. (See
"Oil
Leaks"
under
"Trouble
Shooting"
in Section 9
of
this manual.)
Before removing the
front
seal on the
tiller
transmission,
you
must remove the engine (see
engine removal instructions, page 148, Section
8
of
this manual) and
the
lower
drive
pulley
(part #1008-1
)-see
Photo 8/24. You must also
remove the
two
snap rings retaining the
lower
transmission pulley,
the
drive shaft key, and
the three hex head bolts securing the
front
bear-
ing cap (part #1114).
REMOVING
THE
PULLEY SNAP RINGS
To
remove the snap rings (retaining rings)
that
limit
the
front-to-back
movement of
the
transmission pulley, you will need a pair
of
small, external snap ring
pliers-see
Photo
8/25. They can be obtained
from
a
good
hard-
ware
or
auto
supply
store.
They
also can be
pur-
chased
from
many lawn and garden
equipment
distributors.
It makes
good
sense to have an extra set
of
re-
taining rings (part #9500)
on
hand before
you
start. If you
don't
use snap ring pliers
to
re-
move them,
you
will
spoil the ring's spring ten-
sion. Of course, snap ring pliers will also
be
needed
to
replace the retaining rings
in
their
proper grooves. The
front
snap ring can be re-
moved with
two
screw
drivers,
but
you
must be
careful to avoid
scratching
the surface
of
the
drive shaft.
To
use
two
screw drivers
to
pry
the front snap
ring
out
of
the groove on the shaft (see Photo
8/26), hold pressure on the ring with one screw
driver
while
you
"pee'"
the snap ring
out
of
the
groove with the other. Removing it this way will
probably
ruin the snap ring, so be sure
you
have
another
one available. There
is
substantial
risk in removing
the
rear snap ring
with
two
screw drivers. You
could
scratch the surface
of
the drive shaft.
This
scratch
could
cut
your
front
seal when you install it. It
could
also give
you
problems in installing a worm, spacers and
shims.
