Servicing The Castor Wheels And Bearings; Removing And Installing The Blade(S) - Toro 30722 Operator's Manual

2. Remove the tensioning cap and spacers from the top
of the castor spindle.
3. Pull the castor spindle out of the mounting tube.
Allow the thrust washer and spacer(s) to remain on
the bottom of the spindle.
4. Insert a pin punch into the top or bottom of the
mounting tube and drive the bushing out of the tube
(Figure 25). Also drive the other bushing out of the
tube. Clean the inside of the tubes to remove dirt.

5. Apply grease to the inside and outside of the new
bushings. Using a hammer and flat plate, drive the
bushings into the mounting tube.
6. Inspect the castor spindle for wear and replace it if
damaged.
7. Push the castor spindle through the bushings and
mounting tube. Slide the thrust washer and spacer(s)
onto the spindle. Install the tensioning cap on the
castor spindle to retain all parts in place.
Servicing the Castor Wheels
and Bearings
The rear castor wheels rotate on high-quality roller bearings
which are supported by spanner bushings. Even after
many hours of use, provided that the bearing was kept
well-lubricated, bearing wear will be minimal. However,
failure to keep the bearings lubricated will cause rapid wear. A
wobbly castor wheel usually indicates a worn bearing.
1. Remove the capscrew and locknut holding the castor
wheel and (2) washers between the castor fork
(Figure 26).
2. Pull the spanner bushing out of the wheel hub
(Figure 26).

3. Remove the bushing from the wheel hub and allow the
bearing to fall out (Figure 26). Remove the bushing
from the opposite side of the wheel hub.
4. Check the bearing, spanner, and inside of the wheel
hub for wear. Replace damaged parts.
5. To assemble the castor wheel, push the bushing into
the wheel hub. Slide the bearing into the wheel hub.
Push the other bushing into the open end of the wheel
hub to captivate the bearing inside the wheel hub.
6. Carefully slide the spanner through the bushings and
wheel hub.
7. Install the castor wheel assembly and (2) washers
between the castor fork, and secure all parts in place
with the capscrew and locknut.
8. Lubricate the castor wheel bearing through the grease
fitting, using No. 2 general purpose lithium grease.
Removing and Installing the
Blade(s)
The blade must be replaced if a solid object is hit, the
blade is out-of-balance, worn, or bent. Always use genuine
Toro replacement blades to ensure safety and optimum
performance. Never use blades made by other manufacturers
because they could be dangerous.
1. Raise the cutting unit to the highest position, engage
the parking brake, stop the engine, and remove the
