7.14 CHECKING THE TENSION OF THE TRANSMISSION BELT
The belt tension can be tested with a Frequency tension Tester Optibelt 3 TT or manually by pushing with a force of 4,8 kg or
10,6 lbs at point A. The deflection of the belt must be 5,6 mm or + 0,22 Inch. It is recommended that the tensioning of the belt
be measured with a Frequency tension Tester Optibelt 3 TT. The tension of the belt should read 98 1/s (Hz).
NEVER “OVER” TENSION THE BELT, THE BELT WILL BE DESTROYED AND IT WILL NEVER RECOVER ITS ORIGINAL
TENSION
Loosen the contra nuts (Fig. 7.14.3), loosen slightly the three bolts of the tension device (Fig. 7.14.2), and adjust the tension
with the nut. When the right tension is reached: close the contra nuts and the three bolts of the support. Reassemble in the
same manner.
