Replacing Belt and/or Adjusting Tension
IMPORTANT: If a belt is to be reused, it should be installed in the same direction of rotation
as before.
NOTE: Belt deflection is to be measured on the belt at the location that has the longest
distance between two pulleys.
1. Loosen the 16 mm (5/8 in.) locking nut on the adjustment stud.
2. Turn the adjustment stud and loosen the belt.
3. If a new serpentine drive belt is required, remove the old belt and install a new belt onto
the pulleys.
4. Put a wrench on the adjustment stud 16 mm (5/8 in.) locking nut.
5. Use a 8 mm (5/16 in.) socket and tighten adjusting the stud to adjust the belt deflection.
6. Using one of the 2 methods following, check for correct deflection.
a. Push down with moderate thumb pressure on the longest stretch of belt. Proper
deflection is 13 mm (1/2 in.).
b. Attach the Kent Moore© Belt Tension Gauge to the belt. The gauge has different
ranges for new and used belts.
