Servicing the Front Wheel
Castor Bearing
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 the bearings lubricated will cause rapid
wear. A wobbly caster wheel usually indicates a worn
bearing.
1. Remove the capscrew and locknut holding the castor
wheel and 2 washers between the caster fork (Fig. 31).
2. Pull the spanner bushing out of the wheel hub (Fig. 31).
