Fig.269: Hexagonal shaft mount
The hexagonal shafts (1) are fixed on both
sides of the conveyor with brackets. When
you dismantle the hexagonal shaft, you only
need to take off one of these brackets.
► Remove the screws (4) fastening the
hexagonal shaft mount (2)
(Allen key 3)
and remove the plastic bearings (3)
on
both sides of the conveyor.
CAUTION
Plastic bearing
Make sure that you do not lose the plastic bearings when dismantling the bracket. When
you dismantle a bracket, always remove all the plastic bearings on this bracket and the op-
posite bracket. These would otherwise obstruct the movement of the hexagonal shafts and
could easily fall out.
► In order to prevent a plastic bearing from falling out and to make subsequent fitting
easier, these can be fixed in place with adhesive tape.

NOTICE!
Many tasks on the conveyor require
you to simply move the hexagonal
shafts instead of removing them. In
these cases, you generally do not
need to dismantle the ball studs on the
ends of the hexagonal shafts.
.
► Unscrew the two ball studs (2) from the
two ends of the hexagonal shaft (1)
(fork wrench size 8 and10). This
shortens the shaft and makes it easier
to handle.
► Unthread the hexagonal shaft.
Installation
Follow the removal instructions in reverse order for installation. Also observe the following instruc-
tions:
► Once you have loosened the ball studs of the hexagonal shafts, tighten these with a torque of
14 Nm.
► Make sure that the hexagonal shafts are not damaged by the tool.
► Do not tighten the screws fastening the hexagonal shaft holder too much yet.
► Check whether the tape drive and the drive unit are aligned correctly to one another.
To do this, push the conveyor sides together until you can still just reach the fastening screws.
Check the conveyor drive for ease of movement by turning the hexagonal shaft. You may
need to loosen the conveyor drive again and then reset it.

Spacer disks, if needed:
:When replacing a clamping plate, we recommend that you also replace the spacer disks at
the same time. However, these can also be replaced independently of the clamping plate:
– Shim for clamping plate [03091791-xx] (8x per clamping plate)
– Disk for clamping plate [03091711-xx] (8x per clamping plate)

Removal
► Use the software to move the conveyor sides into a position which allows you best access. As
an alternative, you can loosen the clamps for the relevant sides in dual conveyors.
7.2 "Loosening the Conveyor Side Clamps" [}162]
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
1.2 "Preparatory work..." [}16]
► Loosen the movable idler pulley.
► Unthread the conveyor belt.
► Remove the top holding bolt on the spring and then remove the spring. Make sure that you do
not lose the springs.
Fig.273: Bushing
► Remove the top retaining screw on the
spring (2)
. Make sure that you do not
lose the spring and the bushing (1)
on
the screw. Repeat this step for the
second clamping plate spring.
