1.
Remove both screws at the rear of the rear cover. Grasp the right side of the rear cover and rotate it
counterclockwise to remove the cover. Grasp the left side of the rear cover and rotate it clockwise to remove the
cover. Refer to procedure 7.1.
WARNING
Before continuing with this procedure, review the Warning and Caution statements listed in Section One, Things You
Should Know.
WARNING
If the EFX has been in recent use, the load resistors and mounting bracket may be extremely hot.
2.
Remove the two screws that retain the black plastic shield on the left side of the EFX. Remove the black plastic
shield from the EFX.
3.
Place a 20030-108 or equivalent belt gauge on the input belt as shown in Diagram 8.2.1.
Diagram 8.2.1 - Input Belt Tension Measurement
4.
The belt gauge should read approximately 160 lbs. If the belt tension is significantly high or low the belt tension
may be adjusted using the adjustment bolts shown in Diagram 8.2.1. 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.
