Servicing The Castor Wheels And Bearings; Checking For A Bent Blade - Toro 30366 Operator's Manual

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 27). 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
1. Remove the locknut from the bolt holding the castor
wheel assembly between the castor fork (Figure 28).
Grasp the castor wheel and slide the bolt out of the
fork or pivot arm.
2. Remove the bearing from the wheel hub and allow
the bearing spacer to fall out (Figure 28). Remove
the bearing from the opposite side of the wheel hub.
3. Check the bearings, spacer, and inside of the wheel
hub for wear. Replace any damaged parts.
4. To assemble the castor wheel, push the bearing into
the wheel hub. When installing the bearings, press
on the outer race of the bearing.

other bearing into the open end of the wheel hub to
captivate the bearing spacer inside the wheel hub.
6. Install the castor wheel assembly between the castor
fork and secure it in place with the bolt and locknut.

Checking for a Bent Blade

1. Position the machine on a level surface. Raise the
cutting unit, engage the parking brake, put the
traction pedal in neutral, put the PTO lever in
the Off position, stop the engine, and remove the
ignition key. Block the cutting unit to prevent it from
accidentally falling.
2. Rotate the blade until the ends face forward and
backward. Measure from the inside of the cutting
unit to the cutting edge at the front of the blade
(Figure 29), and remember this dimension.
3. Rotate the opposite end of the blade forward.
Measure between the cutting unit and cutting edge
of the blade at the same position as in step 2 The
difference between the dimensions obtained in
steps 2 and 3 must not exceed 1/8 inch (3 mm). If
the dimension exceeds 1/8 inch (3 mm), replace
the blade because it is bent; refer to Removing the
Cutting Blade.
