1. Remove the Top Shroud, Left Shroud and Right Shroud
from the Main Unit. Refer to the “Replace the Shrouds”
procedure.
2. To test the Drive Belt tension:
• Push the Drive Belt downward at the midpoint (M)
between the pulleys and measure the distance. The
Drive Belt should have only 0.25” (0.64 cm) of give. See
Figure 1.
Or:
• Hold the edges of the Drive Belt at the midpoint (M) and
twist it (see Figure 2). It should turn only 90 degrees
(1/4 turn, to vertical).
If the tension is correct, go to Step 6.
If the tension is too loose or too tight, adjust the position of the
Flywheel. Continue to Step 3.
3. To loosen the Flywheel hardware (A), use a 15 mm
open end wrench to hold the nut on one side steady and
loosen the nut on the opposite side with a 15 mm socket and
wrench.
4. Move the Flywheel in the Main Frame bracket as
necessary to adjust the tension. Hold it in position and
tighten the hardware.
1RWH This step may require two people.
To tighten the Flywheel hardware, use a 15 mm open
end wrench to hold the nut on one side steady and
tighten the nut on the opposite side with a 15 mm socket
and wrench.
5. Carefully turn the crank arms and check the movement
of the drive belt. The Crank Arms and Flywheel should move
as one.
