Grinder Maintenance

Replacing the Teeth

Service Interval: Before each use or daily—Check the
condition of the teeth and rotate or
replace any that are worn or damaged.
Due to the high amount of wear placed on the teeth, you will
need to rotate and replace them periodically.

Each tooth is indexed with three 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 62). Push the tooth forward and rotate it one third
of a turn, bringing an unused edge to the outside. Torque the
nut securing the tooth to 37 to 45 N-m (27 to 33 ft-lb).
To replace a tooth, remove the nut securing the tooth to
remove it, then install a new tooth and nut in the same
position (Figure 62). Torque the nut securing the tooth to
37 to 45 N-m (27 to 33 ft-lb).
