Installing External Wheel Spindle - Grizzly T27400 Owner's Manual

Installing External
Wheel Spindle
The external grinding wheel is used to grind the
outside surfaces of a concentric workpiece. To
configure the grinder for this type of operation,
you will need to remove the internal wheel spindle
(if installed), install the external wheel spindle, and
change the spindle belt.
Note: The T27400 is shipped with a factory-
installed external grinding wheel. Steps required
for installing the external wheel are similar to the
steps for installing the internal wheel. Use the
photos in the Internal Wheel subsection begin-
ning on Page 21 for a visual reference when fol-
lowing this procedure.
