4. The belt gauge should read 100 lbs. If the belt tension is significantly high or low the belt
tension may be adjusted using the adjustment bolts shown in Diagram 5.2. To adjust the
belt tension first straighten the locking tabs on both bolts. When adjusting the tension, turn
both bolts equal amounts. When the adjustment is complete the step up pulley shaft must
remain perpendicular to the frame and drive belt. Turning the adjustment bolts clockwise will
increase belt tension, turning the adjustment bolts counter-clockwise will decrease belt
tension.
5. Changing the tension of the input drive belt will also affect the tension of the generator belt.
If the input belt tension has been changed, continue with step 7.
6. Place a 20030-108 or equivalent belt gauge on the generator belt as shown in Diagram 5.4.

7. The belt gauge should read 60 lbs. If the generator belt tension is significantly high or low, it
may be adjusted using the adjustment bolt shown in Diagram 5.3. First loosen, but do not
remove the four generator mounting bolts and the jam nut. Hold the adjustment bolt head
with one wrench and turn the adjustment nut to change the belt tension. When the tension is
correct, tighten the jam nut. Tighten and torque the four generator mounting bolts to 150
inch pounds.
