the
Owner/Operator
Manual
for
instructions on
how
to remove the
bolo tine holders.
1.
Remove the five bolts (1) and
nylon washers (2), if any, that
secure the tiller housing cover (3).
Discard the washers. Have a pan
ready
to
catch the gear oil that will
pour
out
when you remove the
housing cover in the next step.
2.
Remove the housing cover by
gently tapping the right side of the
tine shaft inward with a soft mallet.
3.
Discard the tiller housing
cover gasket(s) (4).
4.
Use a soft mallet to strike
inward on the right side
of
the
tiller tine shaft (5). If necessary,
strike downward on the right side
of
the shaft. This will collapse the
right side oil seal (6) and help the
tiller cluster to come out.
5.
Remove the tiller tine shaft (5)
and the attached gear and bear-
ings from the tiller housing.
6.
It
is
possible that you are re-
moving the tiller tine shaft
as
part
of
the tiller drive shaft removal
procedure. Regardless of why you
are removing the tiller tine shaft,
you must replace the oil seals.
When you have the opportunity,
perform the following two steps.
a.
Put the tiller housing cover on
an
open vise so that the ends of
the cover are supported. Tap out
the oil seal (6) and discard it.
Note: Do not
pryor
tap directly
on the side
of
the cover. Doing so
could damage
or
score the bear-
ing
cup
or
the inside
of
the cover.
b.
Turn the transmission housing
on one side and tap out the oil
seal (6) from the right side
of
the
housing.
Note: Be careful
not
to damage
or
score the bearing cup
or
the
inside
of
the housing.
7.
Remove the bearing
cup
(8)
from the right side of the tiller
housing, using a punch to drive
the
cup
inward. Be careful
not
to
damage the inside of the tiller
housing.
Note:
You
only
need to remove
this bearing cup if you will be
using a new right side roller bear-
ing. If you replace a bearing you
must also replace the bearing cup.
Keep each bearing cup paired
with its bearing if you intend to
reuse them. Each bearing
cup
wears differently according to its
bearing.
8.
Use a punch to remove the
bearing cup from the housing
cover (only if you are installing a
new left side roller bearing).
9.
To disassemble the gear and
bearing assembly:
a.
Place the tiller tine shaft
assembly on
an
arbor press.
