V-belts

Checking condition

D

Check V-belts for cracks, oil, overheat-
ing and wear

D

Change demaged 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 

Â

 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 indicator 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.
