9.  Set the wrenches aside and carefully remove 

the wheel and hub assembly with the hub 

puller still installed (Figure 27).

12.  To install the grinding wheel and hub, 

complete the preceding steps in the reverse 

order, but skipping the steps regarding hub 

puller usage. After the grinding wheel and 

hub are installed, many machinists still 

choose to dress the grinding wheel. Refer to 

Wheel Dressing on Page 25 for details.

10.  Unthread the hub puller and set it aside. 

11.  Wipe the spindle and hub taper (Figure 28), 

so the tapers are perfectly clean. Wiping the 

threads and tapers with a lightly-oiled rag is 

acceptable to prevent rust and still to allow 

for a tight fit.

Do not assume that a wheel is in sound condition 

just because it is new—damage can often occur 

during shipping, with age, with prolonged 

exposure to moisture, or because of improper 

storage. 

To inspect a wheel for damage: 

1.  Remove the wheel and look for any cracks, 

chips, nicks or dents in the surface of the 

wheel. If you see any of these, DO NOT 

attempt to use the wheel. 

2.  Do a ring test. This test will give you an 

indication of any internal damage that may 

not be obvious during a visual inspection. 

3.  Inspect the paper washers on both sides 

of the grinding wheel (Figure 29). These 

washers are cushions between the spacer 

washer and the grinding wheel seat. Without 

the washers, cracks can be spawned from 

the center of the wheel when the spanner 

nut is tightened. Over time, these cracks can 

radiate outward and the wheel may explode 

during operation, 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. Be sure to 

transfer any RPM limitations and wheel type 

information.
