IMPELLER:
The impeller is fastened to the motor shaft and should need no
replacement for the life of the dryer, (Page 9-11, Figure 10).
V-BELTS:
The V-belts should have a tension that permits approximately 1/2” of
displacement under a normal thumb pressure exerted at mid span. If too loose,
belts will slip; if too tight, belts will cause undue wear of the bearings.
Misaligned pulleys will cause excessive belt wear. Belts should be periodically
cleaned and treated with a proper conditioner for increased life.
