Caster Wheel Bearing Service - Toro Groundsmaster 300 Series Service Manual

Caster Wheel Bearing Service (Fig. 13)
The rear caster 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 bearings lubricated will cause
rapid wear. A wobbly caster wheel usually indicates a
worn bearing.
1. Remove capscrew and locknut holding caster wheel
between caster fork.
2. Pull spanner bushing out of wheel hub.
3. Remove bushing from wheel hub and allow bearing
to fall out. Remove bushing from opposite side of wheel
hub.
4. Check the bearing, spanner and inside of wheel hub
for wear. Replace defective parts.
5. To assemble the caster wheel, push bushing into
wheel hub. Slide bearing into wheel hub. Push other
bushing into open end of wheel hub to captivate the
bearing inside the wheel hub.
6. Carefully slide spanner through the bushings and
wheel hub.
7. Install caster wheel assembly between caster fork,
and secure all parts in place with capscrew and locknut.
8. Lubricate caster wheel bearing through grease fitting,
using No. 2 general purpose lithium grease.
