Replacing the Teeth

Service Interval: Before each use or daily—Check
Due to the high amount of wear placed on the teeth,
you need to rotate and replace them periodically
(Figure 27). Before you rotate or replace them,
inspect each tooth holder on the wheel, including the
flat lands that prevent the teeth from rotating. If the
tooth holder is damaged, replace the wheel. Torque
the nuts 68 N∙m (50 ft-lb) for any teeth that you are
not rotating or replacing.
1. Sharp tooth
Each tooth is indexed with 3 positions so you can
rotate it twice, exposing a new sharp edge before
replacing the tooth. To rotate a tooth, loosen the nut
