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, and install the
tensioning cap on the castor spindle.
Servicing the Castor
Wheels and Bearings
1.
Remove the locknut from the bolt holding the
castor wheel assembly between the castor fork
(). 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 (). 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.
5.
Slide the bearing spacer into the wheel hub.
Push the 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.
Servicing the Cutting
Blades
Blade Safety
A worn or damaged blade can break, and a piece of
the blade could be thrown toward you or bystanders,
resulting in serious personal injury or death.
•
Inspect the blade periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.
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 O
FF
position, shut off 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 (
), and remember this dimension.

Figure 26
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
The difference between the dimensions
obtained in steps
and
must not exceed 3
mm (1/8 inch). If the dimension exceeds 3 mm
(1/8 inch), replace the blade because it is bent;
refer to
Removing and Installing the Blade(s)
(page 20)
.
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.
