Procedure 5.2 - Checking Drive Belt Tension
1. Remove the left hand, right hand and rear cover sections per Procedure 7.1
2. Place the belt tension gauge on the primary (wide) drive belt as shown in Diagram 5.2. The
gauge should read approximately 100 pounds.

3. If necessary, adjust the primary drive belt tension using the two tension adjusters (one on
each side of the secondary sheave) until the tension gauge reads approximately 100
pounds. There are locking tabs on the tension adjusters that must be straightened in order
to turn the adjuster bolts. See Diagram 7.7. Bend the tabs back into the locking position
when the belt tension adjustments are complete.
4. Changing the tension of the primary drive belt will affect the generator belt tension. If the
tension was primary drive belt tension was changed in step 3, continue with step 5.
5. Place the belt tension gauge on the generator (narrow) belt as shown in Diagram 5.3. The
belt gauge should read approximately 80 pounds.
6. Loosen but do not remove the four generator mounting bolts. Using the slots in the frame
and a flat metal bar as a lever, move the generator forward or backward as required to set
the belt tension at 80 pounds and torque the four generator mounting bolts to 40 inch
pounds.
7. Replace the left hand, right hand and rear cover sections per Procedure 7.1.
