Fan Belt Adjustment
The supply fan belts must be inspected periodically to
assure proper unit operation.
Replacement is necessary if the belts appear frayed or
worn. Units with dual belts require a matched set of
belts to ensure equal belt length. When installing new
belts, do not stretch them over the sheaves; instead,
loosen the adjustable motor-mounting base.
Once the new belts are installed, adjust the belt tension
using a Browning or Gates tension gauge (or
equivalent) illustrated in
Figure 109, p. 137 .
