Handbook 
Method of Belt Tensioning using BeltTension indicator
Calculate the deflection in mm on a basis of 16mm per meter of center distance Centre distance(m)*16=deflection(mm)
Set the lower marker ring at the deflection distance required in mm on the lower scale
Set the upper market ring against the bottom edge of the top tube
Place the belt tension indicator on top of the belt at the centre of span and apply a force at right anles to the belt deflecting it to the point where the lower market ring is levei with the top of the adjacent belt
Read off the force value indicated by the tope edge of the upper market ring
If a Fenner Belt Tension Indicator is not available a spring balance and rule will suffice.
NOTE:For single belt drives a straight edge shoude be placed across the two pulleys to act as a datum for measuring the amount of defection If the measured force falls within the values given,the drive shoule be satisfactory
A measured force below the lower value indicates undertensioning
A new drive should be tensioned to the higher value to allow for the normal drop in tension during the running-in period.
After the drive has been running for 30 minutes, the tension should be checked and re-adjusted to the higher value, if necessary
TROUBLE SHOOTING
Small cracks on v-Belt side and base
Generally caused by shortage of belt tension but excesscive heat and/or chemical fumes can also be given same failure.
V-Belt swelling or softening
Caused by excessives contamination by oil, certain cutting fluids or rubber solvent.
Whipping during running
Usually caused by incorrect tensioning, principally on long centre drives.If a slightly higher(or lower)tension does not cure the problem there may be a critical vibration frequency in the system which requirew.
Calculate ONE SHOT TENSIONING
Belts are built right form the start to ensuer totally precise inherent length, to stay matched during storage and on the drive, Now, after extensive field tests, our claim of genuine "one shot" tensioning has been endorsed by satisfied customers all over the world on all belt sections.
Simply put the belts around the pulleys, set them to the appropriate tension value stated in the "Tensioning Force" table below(using the Belt tension indicator as shown),run the drive under load for 30 minutes, stop the drive, check the tension, resetting to catalogue value if necessary On a properly designed drive for the application there will be no need for any further attention during the life of the drive.
