Grain elevator
Installing the clean grain auger
1. Turn the grain tank auger in through the assembly
slot on the left-hand side of the combine. At the
same time slide on the sprocket (4) and the set
collars (2).
(Fig. 34, 35)
2. Install the flange ball bearings on both sides of the
machine and tighten. Align the grain auger so that
the shaft shoulder makes contact with the inner
race of the lock collar bearing on the left-hand
side.
3. Secure the flange ball bearing with the lock collar,
then secure the lock collar. Check the auger for
free and easy rotation.
4. Align the V-belt pulley and insert the key. Install
and tension the V-belt (15). To retension, preten-
sion the compression spring (D) with the nut (E) to
the gauge rod length. Lock the nuts (K and E) and
tighten clamping bolt (A) on the jockey pulley.
(Fig. 36)
5. Align sprocket (4) so that it is centred to the
elevator, then secure the sprocket with the set
collars (2).
(Fig. 35)
6. Insert the cap. Connect the two ends of the chain
with the chain connector at the bottom.
7. Tension the chain using the hex. nut (M) so far that
the paddles do not scrape the elevator housing. It
must be possible to push the conveyor chain to
the side manually at the bottom chain wheel.
Secure the adjustment with the lock nut (G).
