Castor Wheel and Bearing Service

The castor wheel rotates on a high–quality roller bear­ ing. Even after many hours of use, provided that the bearing was kept well–lubricated, bearing wear will be minimal. However, failure to keep bearing lubricated will cause rapid wear. A wobbly castor wheel usually indi­ cates a worn bearing.

1.Remove locknut from capscrew holding castor wheel assembly between castor fork. Grasp castor wheel and slide capscrew out of fork.

2.Remove bearing from wheel hub and allow spacer to fall out. Remove bearing from opposite side of wheel hub.

3.Check the bearings, spacer and inside of wheel hub for wear. Replace defective parts as required.

4.To assemble the castor wheel, push bearing into wheel hub. Slide spacer into wheel hub. Push other bearing into open end of wheel hub to captivate the spacer inside the wheel hub.

5.Install castor wheel assembly between castor forks and secure in place with capscrew and locknut.
