Belt Tensioning
5.
Tighten the adjusting bolt two full turns to attain 50 to 70 pounds belt tension. One
full turn of the adjusting bolt yields approximately 10 pounds change in belt tension.
CAUTION: Do not over tension the drive belt.
6.
Torque the adjusting bolt jam nut and idler sheave screw per Appendix B of this
manual.
7.
Confirm that belt tension is 50-70 pounds by one of the following methods:
a.
Use a direct reading Belt Tension Gauge such as Borroughs Tool Number
BT-33-73F or equivalent.
b.
Apply a five pound load at the center of the longest belt span. Measure belt
deflection at the center of the load point. Correct deflection should not exceed
0.30- 0.40 inches.
8.
If the belt tension is not within the specified tolerance, loosen the jam nut and slide
nut and repeat steps 6-9.
9.
After approximately 5 hours of operation with the new belt, check the belt tension
and adjust as required to maintain 50 to 70 pounds of belt tension.
