Servicing the Caster-Arm
Bushings
The caster arms have bushings pressed into the top
and bottom of the tube, and after many hours of
operation, the bushings wear. To check the bushings,
move the caster fork back and forth and from side to
side. If the caster spindle is loose inside the bushings,
the bushings are worn and must be replaced.
Remove the tensioning cap and caster fork

Note:
Record the position of the washers and
spacers before you remove them so that you do not
need to adjust the deck pitch.
