Assembly note
Cell discs and spacers are assembled with
shims to keep the roller assembly tight, thus
ensuring that no seed will enter between cell
discs and spacers.
Roller for fine seeds
The spacers are equipped with bearings.
Depending on the manufacturing tolerance
shims are added to avoid any friction between
cell discs and spacers.
After the assembly of all parts the remaining gap
to the lock washer is filled up with shims.
Finally assemble the lock washer.
With the roller correctly assembled the cell discs
between the spacers can just be freely turned.
The parts should not rub against one another,
but the clearance should be as small as possible.
When checking against a light source the gap
should just be visible.
On machines with double Venturi area
and 2 seed boxes you may only use
rotors with 2 cell discs.
Otherwise the seed is unevenly distrib-
uted to the two halves.
Installation
The anti-rotation locks must be turned towards
the recess in the housing in order to remove and
assemble the rollers.
Assembly of roller for fine seeds
Maintenance
The function and operability of fine seed rollers
must be checked every day.
¾
There should be no gap between the cell
discs. If the gap is too big, additional shims
must be added.
¾
The cell discs must be light turning. Dressing
or similar materials must not block cell discs
or bearings.
¾
The safety clips must be in place and correctly
assembled to avoid the formation of a gap.
