Once the belt tension is correct, check and adjust final wheel alignment as follows:
NOTICE
To minimize change in belt tension, use LEFT SIDE adjuster only to make final adjustments to belt alignment.
  1. Rotate the wheel BACKWARD. Tighten LEFT SIDE adjuster until belt comes off inside sprocket flange during backward wheel rotation.
    IMPORTANT

    The belt should track to the center of the sprocket tooth surface when properly aligned . Sprocket teeth should be visible on both sides of the drive belt.

  2. Rotate the wheel in the FORWARD direction and verify that sprocket teeth are still visible on both sides of the drive belt .Image
  3. If necessary, loosen the axle nut and LEFT SIDE adjuster until belt just moves off the right flange and begins to track down the center of the driven sprocket flange during forward wheel rotation.
    NOTICE

    It may be necessary to loosen the axle nut and tap the left end of the axle to ensure it moves forward when the adjuster is loosened. The axle nut must be retightened to the ADJUSTMENT SPECIFICATION before proceeding.

  4. Rear wheel alignment is satisfactory when the drive belt remains centered on driven sprocket during forward and backward wheel rotation. Sprocket teeth should be visible from both sides of the drive belt.
  5. Verify that drive belt tension is still within specification.
  6. Tighten rear axle nut to specification.
