4.14  Eccentrics adjustment, belt tension

After removing the belt, it is necessary to align the eccentrics.

Put the belt back on, tighten it with the belt tensioner (2), and check that the arrows at the end of the 

shafts (1) are pointing towards each other. See figure below.

If the marks are not aligned like in the figure, it might be necessary to move the belt a notch or two on 

one of the wheels. This is done by loosening the belt tensioner (2) again, and then lift the belt up from 

the big wheel and move it a notch on the wheel. Then tighten the belt.

2

1

Hold away 

from belt

When pushing in by hand,

the distance should be 

approx. 10 - 15 mm.

The belt tension is controlled/adjusted like 

this:

Remove the flexible tensioner from the belt.

Now the fixed tensioner (2) should be adjusted 

so it is possible to press the belt inwards about 

10 - 15 mm. Then adjust the flexible tensioner 

so the belt runs without vibration.
