V-Belt Tension & Replacement - Grizzly G0750GV Owner's Manual

V-Belt Tension &
Replacement
After initial break in, the V-belts slightly stretch
and seat into the pulley. It is important to check
and adjust them to compensate for this initial
wear. Check the tension thereafter on a monthly
basis. If the belts become excessively worn or
damaged, replace them as a matched set.

tensioned when there is approximately
deflection when it is pushed with moderate
pressure, as shown in Figure 125.
