Possible Cause
Drive belt tension is too high.
Belt tracking is off center.
Speed sensor/magnet are
improperly spaced or aligned.
What to Do
 Twist the drive belt with your fingers; it
should twist approximately 90º.
 Locate the double nut on the adjuster rod
(Figure 2.7). Loosen the first one, back off
the other one full turn, then re-tighten
the first. Recheck the drive belt tension
as above, making sure that slippage does
not occur between the belt and the pulley
while pedaling the unit and when changing
direction while pedaling.
 The drive belt should ride in the center, not
shifted to the right or left (Figure 2.8). If
it is off center, you may feel some added
resistance and will hear a rubbing or
swishing noise.
 Inspect the belt tensioner (Figure 2.8). If it
is bent, causing the belt to be off center,
replace it following the directions in Section
III.
 The speed sensor and magnet must be
properly aligned and separated by the
proper distance, as shown in Figure 2.9.
 To adjust the position of the speed sensor,
loosen the set screw and gently slide the
speed sensor wire harness so that it is
approximately 1/8-inch from the magnet,
and level, then re-tighten the screw.
