Note: A replacement spindle bearing set contains two (2) complete bearings
(cups and cones), a spacer ring and a large snap ring
cannot be purchased separately. 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 (Figure 334). These parts cannot be purchased separately. Do Not mix
bearing spacers from one deck spindle to another.
If new bearings are installed into a used spindle housing, it may not
be necessary to replace the original large snap ring (item 13). 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. Use an arbor press to install any drive studs previously removed.
