5.2.3 Mounting the support walls
Replacing the lateral support walls (13) is practically only required if the material of
the crushing plates (18. 22) is replaced by another one (i.e. from tool steel to
stainless steel) and if even the smallest (P.P.M. range) contamination (abrasion)
from the support walls has to be avoided.
First lift out the fixed crusher jaw (17) as described in chapter 5.2.1.
To replace the left support wall (13), unscrew the belt
guard outside (9) (chapter 5.2.2), remove the V-belt and
pull the fly-wheel (25) off its axle. Then remove the now
visible fastening screws of the support wall (13) and lift
this out from inside.
The fastening screws of the other support wall can be
directly reached. After having unscrewed them, the support
wall can also be removed from the inside.
Replacing the support walls is done the opposite way. The
fastening screws must be very firmly tightened.
After the
installation of the pulley, you have to bring the v-belt to it’s
position. Reattach the belt guard (9).
CAUTION Danger of crushing!
Do not forget to put back the belt guard (9) after
having installed the fly-wheel. This is a safety
precaution.
WARNING The fly-wheel (25) is very heavy. At least 2 people are
required for disassembly.
