Belt Tensioning Procedure Using a Belt Tension Indicator
- Calculate the deflection distance in millimetres on a basis of 16mm per metre of
centre distance.
- Set the lower marker ring at the deflection distance required in millimetres (mm) on
the lower scale.
- Set the upper marker ring against the bottom edge of the tube.
