Note: Your machine may not match the image. For reference only.
1. To test the Drive Belt tension, sit on the bike and use the pedals and
handlebar arms at approximately 20 RPM. Then accelerate quickly (speed
burst) to your maximum ability and feel whether the Drive Belt slips. If
the pedals and arms move normally with no skipping (slip), the tension is
correct.
If the tension is correct—go to Step 19.
If the tension is too loose or too tight—continue to Step 2.
2. Using a 19mm open end wrench, loosen the Fan spindle lock nuts
(A) on both sides of the machine.
3. Using a 10mm open end wrench, adjust the Tension Adjustment
Nuts (B) on the Threaded Tensioner (C) on both sides of the machine.
Gradually turn the Adjustment Nut a 1/4 turn on each side. Tighten
(clockwise) the Adjustment Nuts to increase the belt tension, loosen
(counter-clockwise) to decrease.
NOTICE: Make sure to adjust the tension evenly on both sides of the
machine.
4. Make sure the Fan’s center plane is aligned with the center of the
bike. (See Figures 1 and 2.) If the Fan is not aligned, adjust the Tension
Adjustment Nuts (B). Carefully turn the Crank Arms and check the
movement of the Drive Belt. The Crank Arms and Fan Assembly should
move as one.
!Be sure to keep ngers clear of all pinch hazards when you
turn the Crank Arms.
Repeat Step 1. Adjust the belt tension again if necessary.
5. Retighten the 19mm Fan spindle lock nuts (A). Make sure not to
rotate the shaft as this could damage the RPM Sensor.
6. Test ride the machine to as high a speed as possible, and listen for
unusual noises.
If the machine operates with no popping noises—go to Step 19.
If the Drive Belt or Fan makes noises—continue to Step 7.
NOTICE: It may be necessary to remove the Shrouds for this procedure. Refer to the “Replace the Shrouds” procedure
