V-belts
Checking condition
If, in the case of a multiple belt drive ,
wear or differing tensions are found, al-
ways replace the complete set of belts.
D Check V-belts for cracks, oil, overheat-
ing and wear
D Change damaged V-belts
Checking tension
Use V-belt tension tester to check V-belt
tension.
D Lower indicator arm À into the scale
D Apply tester to belt at a point midway
between two pulleys so that edge of
contact surface Á is flush with the
V-belt
D Slowly depress pad  until the spring
can be heard to disengage. This will
cause the indicator to move upwards
If pressure is maintained after the spring
has disengaged a false reading will be ob-
tained!

Reading of tension
D Read of the tensioning force of the belt at the point where the top surface of the indi-
cator arm À intersects with the scale
D Before taking readings make ensure that the indicator arm remains in its position
If the value measured deviates from the setting value specified, the V-belt tension must
be corrected.
