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 push the lock washer into place.
With the rotor correctly assembled the cell discs
between the spacers can just be freely turned.
The parts must not rub against each other. The
clearance should therefore be as little as possible.
When checking against a light source the gap
should just be visible.
Function test
After installing a new rotor its function and con-
centricity must be checked.
For this purpose switch on the rotor as described
in the section “Calibration test”.
¾
The drive motor must run “smoothly”. No stiff
points should be recognizable.
¾
Check the motor for smooth running. Untrue
running causes inaccurate metering and may
overload the motor.
¾
If possible locate the stiff point.
¾
Rework damaged parts (by machining ...) or
replace.
¾
Loosen the screws on the side covers for drive
motor and rotor bearing and realign the side
covers to release tension.
¾
If the drive shaft has been bent, realign or
replace it.
¾
Remove any foreign bodies that may have
been jammed between rotor and housing.
¾
If dust or dressing in the rotor has entered
between cell discs and spacers dismantle
and clean the rotor.
Rape brushes
The rape brushes clean the cell discs in the ro-
tors for fine seeds.
Before sowing fine seeds the rape brushes must
be installed in the side cover and their function
must be checked.
Rape brushes assembled
¾
Check concentricity and fastening.
¾
Check condition and cleaning effect of
brushes.
¾
Install the side cover with the brushes into the
metering unit.
¾
The brushes must firmly rest against the cell
discs and should rotate with the rotor.
NOTE
The function and cleaning effect of the rape
brushes must be checked before starting sowing
and at regular intervals during work.
Sticking cell discs cause metering errors during
sowing. Less seed is placed.
The side cover with the rape brushes can be
removed even when the seed hopper is full.
Sticking cell discs can then also be cleaned in
assembled condition.
The rape brushes should be disassembled when
sowing normal seeds. The housing holes must
be closed.
