Control of the belt tightness
Control of the V-belt washers and the spindles
Before mounting the V-belts it is necessary to ensure that
the V-belt washers are in alignment and the spindles are
parallel.
Normally, sufficiently precise control can be done by putting
a straight-edge or a cord across the sides of the V-belt
washers.
After mounting and tightening the control is repeated.
Mounting the V-belts
The V-belts should never be forced onto the belt washers
since the transmission cords can be damaged and the life
of the belts will be reduced significantly.
Therefore, the distance between the spindles should be
reduced so that the V-belts can be mounted loosely in the
track of the V-belt washers.
When the set of V-belts has been mounted, the tightness of
the belts can be controlled as simple as follows, giving
sufficient safety that the tightness is correct:
Deflection:

The deflection can be measured by putting a straight-
edge across the belt washers as shown on the drawing
at the right below.
The deflection is = 5,20 mm
When the belt tightening has been done appropriately:
Start the transmission. Let it run for 5 minutes.
The tightness of the belt is controlled and perhaps
adjusted.
After 24 hours in function the tightness is to be controlled again. Hereafter, the tightness should be checked
regularly and kept in the recommended level.
