Reducing Bushings
If reducing bushings are used in a wheel's mounting hole, check that it does not protrude beyond the
surface of the wheel. Bushings that are too thick will not allow the backups to contact the wheel properly.
Do not use wheels that have bushings which are loose in the mounting holes. Do not use shim stock to
tighten or replace bushings.
Wheel Installation
1. Remove the stone guard.
2. Hold the spindle lock pin in while turning the spindle shaft
or stone counter-clockwise (left) until the stops the shaft.
Spindle Lock Pin
3. Holding the pin in, apply enough force to loosen the
retaining nut and remove it (Arrow A).
4. Remove the backup flange and used grinding stone

5. Check that the blotter came off with the stone and did not
stick to the inner backup.
6. Check that the inside backup stayed in place. The square

the backup.
7. Use new blotters between the stone and backups.

The blotters should be supplied with the stones.

They are made from highly compressible material and
should not be more than .025 inches thick.
