I. V-Belts (See illustrations in section F "Pulleys")

V-belts should have proper tension. If too loose, they will slip, excessive wear on the bearings will result. If the pulleys are not properly aligned, excessive belt wear will result. Proper belt tension will allow 1/2" displacement under normal thumb pressure at mid span of belt.

NOTE: Belts must always be replaced in pairs (matched sets).

1.Discontinue power to dryer.

2.Back off jam nuts on idler adjustment belts.

3.Tighten belts by turning both bolts evenly clockwise. (Turn clockwise to loosen belts.)
