Servicing the Blade Spindle (Groundsmaster Series Cutting Units) (continued)
Cutting Units: Service and Repairs
1. Remove the locknut, hardened washer, and pulley from the top of the spindle
shaft.
2. Use an arbor press to remove the spindle shaft from the spindle housing.
Note: Ensure that the spindle shaft spacer remains on the spindle shaft
while removing the shaft.
3. Remove and discard the oil seals from the spindle housing.
4. Remove the bearing cones, inner bearing spacer, spacer ring and spindle
shaft O− ring from the spindle housing. Discard the spindle shaft O−ring.
5. Use an arbor press to remove the bearing cups and outer bearing spacer
from the housing.
Note: The large snap ring can remain inside the spindle housing. Removing
the large snap ring is very difficult.
6. Inspect the drive studs. Use an arbor press to replace any drive studs if
necessary.
Assembling the Blade Spindle
Do not mix the components from one bearing set to another. Replace
the bearings as a complete set only.
Do not mix the components from one spacer set to another. Replace
the spacers as a complete set only.
A replacement bearing set contains 2 bearings, a spacer ring, and a large snap
ring. A replacement spacer set includes the inner spacer and outer spacer.

1. Bearing set
If new bearings are installed into a used spindle housing, it is not
necessary to replace the original large snap ring. If the original snap
ring is in good condition with no sign 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 damaged,
replace the snap ring.
