Using needlenose pliers, carefully release the spring (E1) on the Belt

Tensioner (E).

To remove the hardware from the Flywheel (C), use the 15 mm open

end wrench to hold the nut (F) on one side steady and remove the nut on

the opposite side with the 15 mm socket and wrench. Set the hardware

safely aside.

Remove the Flywheel (C) from the Main Frame brackets (G) and the

Drive Belt (B).

Note:

The Flywheel is heavy.

Remove the old Drive Belt (B) and discard it.

Hold the Flywheel (C) near the Main Frame brackets (G) and put the

new Drive Belt (B) in position on the Flywheel pulley (C1). Put the Drive

Belt in position around the Belt Tensioner (E). Be sure that the upper

portion of the Drive Belt is under the bearings on the Belt Tensioner.

NOTICE:

This step may require two people.

Align the Flywheel axle in the Main Frame brackets (G). Hand tighten

the hardware from step 4 on each end of the Flywheel axle.

Put the Drive Belt (B) onto the Drive Pulley (A). Make sure the Drive

Belt is aligned on the Flywheel pulley (C1), Belt Tensioner (E) and Drive

Pulley.

10.

Before you fully tighten the Flywheel hardware, reattach the Belt

Tensioner spring (E1) with the pliers. Make sure that the belt tension is

correct. Refer to the “Belt Tension Adjustment” section in this manual.

Note:

This step may require two people.

11.

To tighten the Flywheel hardware, use the 15 mm open end wrench

to hold the nut (F) on one side steady and tighten the nut on the opposite

side with the 15 mm socket and wrench.

Note:

Before fully attaching the Shrouds, power up the machine to

verify that the Magnet Arm (D) can move freely, and that the

Brake Magnet and Flywheel (C) do not touch at the maximum

resistance level.

12. Final Inspection

Inspect your machine to ensure that all hardware is tight and components

are properly assembled.

Do not use until the machine has been fully assembled and

inspected for correct performance in accordance with the

Owner’s Manual.
