c. For flat-pulley drive systems, verify allowable
distance of belt from edge of pulley. Refer to
Table 2 below.
d. For variable-speed models only, verify that
V-belts are properly tensioned by applying a
set force to the belts and measuring the
deflection to determine the belt tension. Refer
to Table 3 for the acceptable belt’s tension
ranges. Belt tension measurements should be
taken as close to the center of the belt span as
possible. Refer to Figure 16.
