Servicing Castor Wheel And
Bearing
The castor wheel rotates on a high–quality sealed roller
bearing and is supported by a spanner bushing. Even after
many hours of use the bearing wear will be minimal. A
wobbly castor wheel usually indicates a worn bearing.

assembly in castor fork. Grasp castor wheel and slide
capscrew out of fork.
2.
Remove outer bearing from wheel hub and allow
bearing spacer to fall out. Remove outer bearing from
