a. Hand rotate the pedals and verify that the drive belt does not track either the left
or right so that it rubs against the flywheel pulley left (inner) or right (outer) rims.
If the drive belt rubs against the pulley inner or outer rims, adjust the tracking
alignment to correct the issue:
i. If the belt is tracking to the left causing the belt to rub against the inner
rim of the pulley, adjust the belt to track to the right and remain centered
on the pulley. While rotating the pedals, loosen the LEFT adjustment nut
in 1/8 counter-clockwise increments until the belt moves towards the cen-
ter and no longer rubs against the pulley inner rim.
If the belt moves past the pulley center, slightly tighten (turn clockwise)
the LEFT adjustment nut to recenter the belt.
Continue this process until the belt no longer rubs against either the inner
or outer pulley rims.
ii. If the belt is tracking to the right causing the belt to rub against the outer
rim of the pulley, adjust the belt to track to the left and remain centered on
the pulley. While rotating the pedals, tighten the LEFT adjustment nut in
1/8 clockwise increments until the belt moves towards the center and no
longer rubs against the sprocket outer rim.
If the belt moves past the sprocket center, slightly loosen (turn counter-
clockwise) the LEFT adjustment nut to recenter the belt.
Continue this process until the belt no longer rubs against either the inner
or outer sprocket rim.
