DISCHARGE CONVEYOR BELT - REMOVAL OF
BELT AND BELT TENSION
(
Figure 21)
1. Turn off the tractor engine, remove the keys and put them in your pocket.
2. Remove motor M, by unscrewing screws B. BE CAREFUL not to lose the key on the drive shaft.
3. Remove the 4 screws C from the body sides. N.B. Given the weight of the frame, it is recommended that
this procedure be carried out by 2 persons.
4. Place the unit on the ground in a vertical position, on the side of the motor housing.
5. Remove tension springs A by unscrewing screws D.
6. Take the roller to the internal limit stop.
7. Extract the belt by pulling upwards. At this point it is possible to see whether there is dirt in the unit. Blow
away using compressed air and clean. Check the position of the scrapers, which must be close to the roller
(around ½ mm clearance). N.B. If the scraper touches the roller there is a risk of causing a high level of
wear and irritating squeaking. The scrapers are fixed to the frame using screws, to adjust them loosen the
screws and move them into the appropriate position.
8. Reassemble everything by reversing the sequence of the last 7 steps.
9. The unloading belt is kept in tension by the springs (Detail A) positioned in the front part of the belt. The
tension of these must be adjusted with the belt at a standstill, checking that the space between the coils is
between 0.5 mm and 1 mm.
10. If the belt has shifted over to one side, adjust one of the 2 spring tension screws, tightening or unscrewing
until the belt is centred. N.B. For trouble free operation of the unloading conveyor, check that the inside of
the belt and also the rollers are clean and that the scrapers are in the correct position.
