Belt Alignment inside Drive Box:
Aligning the belt, so it tracks down in the centre of
the drive roller, is counter-intuitive! It is opposite from
aligning the end rollers.
This time you must loosen the loose side.
This is because the first roller to have contact with
the belt is the pinch roller, but the drive roller (second
in line) is the only one which can be adjusted.
7. Loosen the drive roller bearing housing on the
loose side of the belt.
8. Use the adjustment bolts at the front of the drive
box to move the brackets connected to the drive
roller.
9. The misaligned belt will travel to towards the
loose side of the roller.
- Loosen the loose side, more.
10. Tighten the bearing housing.
11. Run the belt to check it’s alignment.
- Repeat steps if necessary.
12. Replace the housing guard.
Belt Alignment at Discharge Roller:
13. Stop the belt and turn off the engine.
14. If necessary, remove the discharge spout to view
the roller.
Note:
If belt is out of alignment,
it will move to the loose side.
Tighten loose side or loosen tight side.
15. Adjust one side of roller at a time.
- Loosen the bearing housing, then adjust.
16. Tighten the discharge roller bearing housing.
17. Run the belt a couple of revolutions and check
the alignment.
- Repeat steps until the belt runs centred.
18. Replace bearing guard.
