Disassembly (Fig. 13)
1. Loosen and remove lock nut from top of spindle
shaft. Remove hardened washer and pulley from
spindle. For drive spindle, remove hydraulic motor
mount.
2. Remove the spindle shaft from the spindle housing
which may require the use of an arbor press. The spindle
shaft spacer should remain on the spindle shaft as the
shaft is being removed.
3. Carefully remove oil seals from spindle housing tak-
ing care to not damage seal bore in housing.
4. Allow the bearing cones, inner bearing spacer and
spacer ring to drop out of the spindle housing (Fig. 14).
5. Using an arbor press, remove both of the bearing
cups and the outer bearing spacer from the housing.
6. The large snap ring can remain inside the spindle
housing. Removal of this snap ring is very difficult.

Assembly (Fig. 13)
NOTE: A replacement spindle bearing set contains two
(2) bearings, a spacer ring and a large snap ring (items
1, 2 and 3 in Fig. 14). These parts cannot be purchased
separately. Also, do not mix bearing set components
from one deck spindle to another.
NOTE: A replacement bearing spacer set includes the
inner spacer and outer spacer (items 4 and 5 in Fig. 14).
Do not mix bearing spacers from one deck spindle to
another.
IMPORTANT: If new bearings are installed into a
used spindle housing, it may not be necessary to re-
place the original large snap ring. If the original
snap ring is in good condition with no evidence of
damage (e.g. spun bearing), leave the snap ring in
the housing and discard the snap ring that comes
with the new bearings. If the large snap ring is found
to be damaged, replace the snap ring.
1. If large snap ring was removed from spindle housing,
install snap ring into housing groove. Make sure snap
ring is fully seated in housing groove.
