Belt Tension - Schwinn AC Power Service Manual

Belt Tension

1. Use a 9/16" socket to loosen the axle nuts on both sides of
the flywheel.
2. Remove the tension bolt covers from the front of the bike
3. Use a 10mm deep socket to tension/loosen the left and
right tension nuts by turning clockwise to tighten and
counter-clockwise to loosen. Be sure to adjust the bolts
evenly so that the flywheel is not angled between the forks.
4. Check belt tension using a sonic tension meter in the cen-
ter of the belt span. The belt should measure ~100 Hz.
5. If you do not have a sonic tension meter, you can use a
tensioning app to measure the frequency.
NOTE: App settings are provided for convenience. Core
does not support third-party apps.
6. Lower the brake down and ensure that none of the brake
magnets are touching the flywheel.
7. Once the belt has been tensioned so that the correct Hz is
measured and the flywheel has been checked for align-
ment then tighten the axle bolts that were loosened in Step
4.
NOTE: Part of the frame has been moved for clarity
