6. Installation is the reverse procedure. Installation does not
require the use of the crank puller.
To reinstall the Pedals, carefully align the threads and hand tighten
to prevent cross-threading. Then tighten fully with pedal wrench.
Note: The Left Pedal is reverse-threaded. Be sure to attach
Pedals on the correct side of the Bike. Orientation is
based from a seated position on the bike. The Left Pedal
has an "L", the Right Pedal an "R".
7. 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.
