Sieve pan
Installing the 3-D upper sieve frame
1. Lift the upper sieve frame into the combine from
the rear.
CAUTION!
The rubber sealing strips must overlap the sides
of the frame.
2. Press the metal/rubber bearings into the control
arms and connecting rods. The outer metal ring of
the bearing must be flush with the housing.
3. Push studs (3 and 7) into the upper sieve frame
from the outside on both sides of the combine.
4. Secure the four studs with hex. bolts (2).
Tightening torque = 63 Nm
5. Pre-assemble rear control arm (4) and front
control arm (9) with connecting rod (10) on both
sides. Do not tighten bolts (6 and 11) at this stage.
6. On the 3-D version, bolt the control arm to the
upper sieve frame and the metal/rubber bearing.
(Fig. 46, 47, 48)
7. Position the sieve pan exactly in the middle of its
oscillating travel. In this position, secure the metal/
rubber bearings axially by tightening the hex. bolts
and hex. nuts (6 and 11) to the prescribed torque.
Tightening torques:
M 10 – 45 Nm
M 12 – 78 Nm
M 16 – 195 Nm
ATTENTION!
This assembly sequence must absolutely be
followed in order that the rubber bushings of
the metal/rubber bearings are subjected to
the same torsional load on both sides during
the oscillating movement of the sieve pan. If
the sequence is not followed, the rubber
bushings will be subjected to premature
wear.
8. Install the sensor tray.
9. Install the complete tool box assembly and
connect the battery.
10. Install the upper sieves.
11. Adjusting the 3-D sieve pan control system , see
