Replacing the brush
1. Release the three tension springs and remove the
roller brush’s end ring, see figure 19.
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. Insert a brush using the brush ring's "pins" in the
space between the three square sections.
6. Fit a spacer ring.
7. Fit alternating brush rings and spacer rings. Please
note that the brush rings' “carrier pins” must be more
or less evenly divided between the three square
sections. This is so that no single section will be
exposed to all the strain from the brushes.
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 three tension springs.
See figure 19.
Fitting the roller brush
1. Roll in the roller
2. Push the brush in towards the motor package in the
chassis.
3. Lift up the loose slewing bracket, figure 20 and fit it,
see B in figure 17 on page 18.
4. Lower the machine.
5. Re-attach the slewing bracket top, see A in figure 17
on page 18.
Always use Loctite on the screws.
