Belt and Flywheel Replacement
About
This procedure provides instruction to remove and install the Belt and flywheel.
The Poly V drive belt is the latest generation of drive systems for spinner bikes. The flywheel
axle and front pulley are mounted in a fixed position providing front-rear belt pulley alignment.
Also, after the belt tension is set, the belt tensioner mechanism is designed to not require
adjustment and will not allow belt slip.
Belt replacement requires removal of the flywheel so this procedure provides instructions to
remove/install both the belt and flywheel.
WARNING:Personal injury is possible while removing/installing the flywheel. The
flywheel weighs approximately 43 lbs (19.5 kgs) and can pinch or fall onto fingers or
other extremities causing personal injury.

Torque is a measure of the force that can cause an object to rotate about an axis. Bolt/nut
example: 5 NM torque is equivalent to 5 newton's of force applied one meter from the center of
the bolt, 6 ft-lb is equivalent to 6 lbs of force applied 1 foot away from the center of the bolt.
