Sieve pan
Tightening torques of axial mountings for the
upper and lower sieves
(up to serial no. ...)
Upper sieves = 45 Nm (M 12 hex. bolts)
Lower sieve = 23 Nm (M 10 hex. bolts)
Sieves – Basic setting
(electric sieve adjustment – up to serial no. ...)
If the rods have been adjusted, the basic setting of the
sieves has changed and must be reset.
This is done as follows:
1. Unhinge the ball joints of the Bowden cables from
the sieve adjusting levers.
2. Using the rotary switch and +/– keys, move the
sieve adjusting linkage to the “0” position.
3. Fully close the sieve openings.
4. Adjust den cables so that the can be installed
without stress and refit the Bowden cables.
The Bowden cables can be adjusted at the hex.
nuts (A and B at the electric motors) and / or at the
Bowden cable retarders (behind the sieves).
5. Checking the identical positions of frogmouth
sieves:
Open sieves, e.g. to position “15”.
Openings of the left-hand frogmouth sieve must
be identical with the openings of the right-hand
frogmouth sieve.
To check the frogmouth sieve openings use a
gauge (CLAAS special tool, part no. 181 625.0) if
necessary.
With this gauge the lower sieves can be checked
too. But the upper sieves must then be in the fully
open position.
If necessary, set the frogmouth sieves by
adjusting the rods. Make sure sieve openings are
not set too narrow.
To adjust the finishing sieves for identical
openings, one of the upper sieves has to be
removed.
