Possible Cause
What to Do
Machine produces a grinding
sound from the wheel area when
in use.
Cracked or broken wheel.
Inspect the roller wheels. If cracked or
broken, replace according to the directions
in Section III.
Machine produces a popping or
grinding sound from under the
shrouds when in use.
Broken bearing or magnetic
brake/flywheel assembly.
Inspect the magnetic brake/flywheel by the
pulley. If the bearing is cracked or broken,
it will be popped out on the side opposite
the pulley (Figure 2.37) If so, replace the
brake assembly following the directions in
Section III.
Machine produces “clunking”
noise when in use.
Loose links, pivots, or rocker
arms.
Check the rails, wheels, and wheel covers
to ensure that they are not rubbing against
each other or against the back shroud.
Open the top cover and using the moving
handlebars to slowly move the machine
through the full range of motion. This will
help you determine if there is anything
hitting and/or clunking, such as the wire
harness rubbing against another part.
Check to make sure all pivot joints on
both sides of the machine are tight (Figure
2.36).
Check and tighten the four socket head
screws attaching the stability links to the
frame and the four bolts attaching the
crank shaft plate to the large drive pulley
(Figure 2.36).
Try the machine at slow and fast pace,
forward and backward to see if the noise
is still present.
Check the 2-pivot links and the adjustable
link assembly for looseness and side-to-
side motion. A slight side-to-side motion is
normal at the rocker arm and 2-pivot link
connection. No side-to-side motion should
be seen in the adjustable link assembly.
Section III provides directions for replacing
links if necessary.
If the noise persists, detach the crank arm
from the middle adjustable link bolt on
both right and left sides. Move the drive
pulley; if the noise persists you may need
to replace the pivot shaft and/or crank
shaft assembly. Refer to Section III for
directions.
