7. Remove the grinding wheel, as shown in
Figure 17.
Figure 17. Removing wheel.
8. Wipe the grinding wheel seat shown in
Figure 18 so no paper is stuck to the seat.
The seat must be clean and free of debris.
Note: Wiping the threads, grinding wheel seat,
and hub with a lightly-oiled rag is acceptable
to prevent rust.
9. Inspect the paper washers for missing pieces
on both sides of the grinding wheel (Figure
19). The paper washers are cushions
between the spacer washer and the grinding
wheel seat. Without the washers, cracks can
spawn from the center of the wheel when the
spanner nut is tightened. Over time, these
cracks can radiate outward and the wheel
may explode possibly causing injury.

Note: If you need to replace or install new paper
washers, replacements can be cut out of
any thick construction paper or card stock.
Regular notebook paper or paper from a copy
machine is not acceptable, as it is too thin to
provide the required cushion. Don't forget to
record the wheel type and RPM rating on the
new paper washer.
10. Ring test the grinding wheel, even if it is
new, then if the wheel is free of cracks, slide
the wheel onto the hub. Refer to Ring Test
on
Page 25 for details.
11. Complete the preceding steps in the reverse
order to install the grinding wheel.
s
After the grinding wheel is installed, you
will have to use the dressing tool to true-
up the wheel. Refer to Wheel Dressing
on Page 25 for details.
s
When the wheel runs true, the hub and
grinding wheel must then be removed
and balanced as an assembly since
grinding wheels can have different
densities at various points of the
wheel. The wheel will only deliver
superior results if it is properly trued-
up and balanced. Refer to Removing
& Installing Wheel & Hub on Page
22 to remove the assembly; and refer
to Wheel Balancing on Page 26 for
specific procedures on balancing.
