Replacing the brush
1. Loosen the two split pins and remove the roller
brush’s end ring, see figure 12.
2. Pull off the brush and spacer rings. This is most easily
done by hanging up the roller vertically in an
overhead crane or suchlike.
3. Check the core for damage.
4. Lift up the brush core with the bearing shaft facing
downwards on a pair of wooden blocks or suchlike.
This is to prevent damaging the shaft and slewing
brackets.
5. Fit a brush ring so that the “pins” are supported by the
flange on the brush core.
6. Fit a spacer ring.
7. Fit alternating brush rings and spacer rings. Note that
the “carrier pins” on the brush rings must be placed
on opposite sides of the two stops. This is to ensure
the load is distributed evenly over the brush core.
8. To “cover” the entire core it may be necessary to use
double brushes without spacer ring on the end so that
the right length will be obtained.
9. Refit the end ring using the two split pins. See figure
12.
