What to Do
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 the 2-pivot/3-pivot joints on
both sides of the machine are tight (Figure 2.23).
Check and tighten the four bolts attaching the crank
shaft plate to the large drive pulley (Figure 2.24).
Check and tighten the clamp bolt securing the crank
arm (Figure 2.24).
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 3-pivot links 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 3-pivot link assembly. Section III provides
directions for replacing links if necessary.
If the noise persists, detach the crank arm from
the middle 3-pivot bolt on both right and left sides.
Move the large wheel; if the noise persists you may
need to replace the pivot shaft and/or crank shaft
assembly. Refer to Section III for directions.
