Servicing The Castor Wheel And Bearing; Checking For Bent Blade - Toro 30555 Operator's Manual

IMPORTANT: When bushings are installed, the inside diameter
may collapse slightly, and this may not allow the castor shaft to
be installed. If the castor spindle does not slide through new
bushings and mounting tube, ream both bushings to inside
diameter of 28.6 mm.
SERVICING THE CASTOR WHEEL AND
BEARING
The castor wheel rotates on a high-quality roller bearing and is sup-
ported by a spanner bushing. Even after many hours of use, provid-
ed that the bearing was kept well-lubricated, bearing wear will be
minimal. However, failure to keep the bearing lubricated will cause
rapid wear. A wobbly castor wheel usually indicates a worn bearing.
1. Remove the locknut from the capscrew holding the castor
wheel assembly between the castor fork. Grasp the castor
wheel and slide the capscrew out of the fork.
Note: Account for (2) thrust washers.
2. Tip the wheel to the side and allow the spanner bushing to fall
out.
3. Remove one bushing from the wheel hub and allow the bearing
to fall out. Remove the bushing from opposite side of the
wheel hub.
4. Inspect the bearing, spanner bushing and the wheel for wear.
Replace worn, damaged parts.
5. To assemble parts, slide the spanner bushing through the hub
assembly.
6. Mount the castor wheel assembly and washers between the
fork, insert the capscrew and locknut. Tighten the capscrew and
locknut until the spanner bushing and washers bottom against
the inside of the castor fork.
7. Pump grease through the grease fitting on the wheel until the
bearing is greased thoroughly.
CHECKING FOR A BENT BLADE
1. Position the machine on a level surface, raise the cutting unit,
engage the parking brake, be sure the traction pedal is in the
neutral position, the PTO lever in the OFF position, shut off the
engine, remove the key from the switch and disconnect the
