Front Caster Wheel Bearing Service (Fig. 28)
The front 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
a
nd (2) washers between caster fork.
2. Pull spanner bushing out of wheel hub.
3. Remove bushing from wheel hub and allow bearing
to fa
ll out. Remove bushing from opposite side of wheel
hub.
4. Check the bearing, spanner and inside of wheel hub

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
wh
eel hub.

tween caster fork, and secure all parts in place with
capscrew and locknut.
