Rotating or Replacing a Tooth
Due to the high amount of wear placed on the teeth, you will need to rotate and replace them periodically (Figure 1). 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 60 to 76 N∙m (44 to 56 ft-lb) for any teeth that you are not rotating or replacing.
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 securing the tooth (Figure 2). Push the tooth forward and rotate it 1/3 turn, bringing an unused edge to the outside. Torque the
nut securing the tooth to 60 to 76 N∙m (44 to 56 ft-lb).
To replace a tooth, remove the nut securing the tooth, then install a new tooth, washer, and nut in the same position (Figure 2). Torque the nut
securing the tooth to 60 to 76 N∙m (44 to 56 ft-lb).
