Grinder Maintenance
Replacing the Teeth
Service Interval: Before each use or daily—Check the
condition of the teeth; rotate or replace
any that are worn or damaged and torque
the nuts for all teeth.
Due to the high amount of wear placed on the teeth, you
will need to rotate and replace them periodically
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 securing the tooth
(Figure
23). Push the tooth forward and rotate it 1/3 of a
turn, bringing an unused edge to the outside. Torque the nut
securing the tooth to 68 N∙m (50 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
23). Torque the nut securing the tooth to 68 N∙m
(50 ft-lb).
