Servicing Castor Wheels and Bearings
The castor wheel rotates on a high–quality roller bearing
and is supported by a spanner bushing. Even after many
hours of use, provided that the bearing was kept well–lu-
bricated, bearing wear will be minimal. However, failure
to keep bearing lubricated will cause rapid wear. A
wobbly castor wheel usually indicates 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. 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 castor 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
the wheel hub.
7. Install castor wheel assembly between castor fork
and secure in place with capscrew
, washers and lock-
nut.
8. Lubricate castor wheel bearing through grease fit-
ting, using No. 2 general purpose lithium base grease.
