2. INTRODUCTION
Ensures accurate measurement of belt tension. Clear increment and dual scale for ease of use. Tension chart guide is included.
Suitable for belts of varying thickness.
3. INSTRUCTIONS
The Belt Tension Gauge is suitable for use on camshaft drive
belts, and serpentine drive belts. It is designed for ease of use
and can be used to check the tension on a variety of belts where
the movement of the belt is measured by load. There is a clear
increment and a dual scale for accurate measurement of the belt
tension.
NOTE: Always follow the manufacturer’s data for the belt tension
requirements and the correct position of where the belt tension
should be measured. The Belt Tension Gauge is set for 5mm thick
belts but can measure various belt thickness.
3.1. CHECKING THE BELT TENSION
3.1.1. Fit the Belt Tension Gauge on the belt at the correct location as
Detailed by the manufacturer for load testing.
3.1.2. Obtain the manufacturer’s data for belt deection (mm) and load.
(daN).
3.1.3. Using the table supplied, nd the correct tension setting.
3.1.4. Turn the knurled knob until the bevelled edge is on the required tension setting, the increments shown are for precise setting.
3.1.5. The belt tension can now be read from the internal slide. This reading can now be compared to the optimum tension readings on the
table overleaf.
3.1.6. Adjust the belt to the correct tension as required.
3.1.7. If the belt to be tightened is thicker that 5mm, simply add the difference to the tension setting and to the optimum tension.
For example; (Example shown in the shaded area on the table).
Belt thickness = 6mm
Belt load = 4.5 daN
Belt deection = 3.5mm
The tension setting = 16mm + 1mm = 17mm
Optimum Tension = 13mm + 1mm = 14mm
