Servicing The Caster Arms; Servicing The Caster Wheel - Toro 30555 Operator's Manual

Servicing the Caster Arms

The caster arms have bushings pressed into the top and
bottom portion of the tube. Wear can occur over time. Check
the wear of the bushings by moving the castor fork side to
side. Replace both of the bushings if the castor fork has side
to side movement.
1. Raise the mower deck so that the wheels are off the
ground and block it so that it cannot accidentally fall.
2. Remove the caster assembly from the carrier frame
(Figure 11).
3. Use a pin punch or similar tool to remove the bushings
from the tube (Figure
1. Tube
4. Clean the inside of the tube thoroughly.
5. Lightly grease the inside and outside of the replacement
bushings before installing them into the tube.
6. Inspect the castor shaft and replace it if it is worn or
damaged.
7. Install the castor assembly to the carrier frame
11).
Important: When the 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 the new
bushings and mounting tube, ream both bushings
to an inside diameter of 1.126 inches.

Servicing the Caster Wheel

The caster wheel rotates on a roller bearing that is supported
on a spanner bushing. Wear can occur over time. Frequently
lubricate the caster bearing and spanner bushing to minimize
the wear to the assembly.
1. Remove and set aside the lynch pin that secures the
caster assembly to the carrier frame
2. Remove and set aside the bolt and locknut that secure
the caster wheel to the fork.
