Disassembly (Fig. 16)<br />
Assembly (Fig. 16)<br />
1. Loosen and remove lock nut from top of spindle<br />
shaft. Remove hardened washer and pulley from<br />
spindle. For drive spindle, remove hydraulic motor<br />
mount.<br />
2. Remove the spindle shaft from the spindle housing<br />
which may require the use of an arbor press. The spindle<br />
shaft spacer should remain on the spindle shaft as the<br />
shaft is being removed.<br />
3. Carefully remove oil seals from spindle housing taking<br />
care to not damage seal bore in housing.<br />
4. Allow the bearing cones, inner bearing spacer and<br />
spacer ring to drop out of the spindle housing (Fig. 17).<br />
5. Using an arbor press, remove both of the bearing<br />
cups and the outer bearing spacer from the housing.<br />
6. The large snap ring can remain inside the spindle<br />
housing. Removal of this snap ring is very difficult.<br />

NOTE: A replacement spindle bearing set contains two<br />
(2) bearings, a spacer ring and a large snap ring (items<br />
1, 2 and 3 in Fig. 17). These parts cannot be purchased<br />
separately. Also, do not mix bearing set components<br />
from one deck spindle to another.<br />
NOTE: A replacement bearing spacer set includes the<br />
inner spacer and outer spacer (items 4 and 5 in Fig. 17).<br />
Do not mix bearing spacers from one deck spindle to<br />
another.<br />
IMPORTANT: If new bearings are installed into a<br />
used spindle housing, it may not be necessary to replace<br />
the original large snap ring. If the original<br />
snap ring is in good condition with no evidence of<br />
damage (e.g. spun bearing), leave the snap ring in<br />
the housing and discard the snap ring that comes<br />
with the new bearings. If the large snap ring is found<br />
to be damaged, replace the snap ring.<br />
1. If large snap ring was removed from spindle housing,<br />
install snap ring into housing groove. Make sure snap<br />
ring is fully seated in housing groove.<br />
