1. Turn the energy wheel clockwise (as viewed from the
pulley side) by hand to verify that the wheel turns
freely through a full rotation.
2. Confirm that all wheel segments are fully engaged inthe wheel frame and that the segment retainers are
completely fastened. See Figure106, p. 156.
3. Manually rotate the energy wheel clockwise through several
 rotations to confirm the seal adjustment and
proper belt tracking on the wheel rim. Correct belt

Note:Pile seal brackets are fixed with a single screw to
the cassette frame near the ends of the wheel
bearing beam. Because the height of the belt link is
slightly higher than that of the urethane belt, a rare
interference may occur when it passes the seal
bracket. If this occurs, remove the interfering
bracket(s). No measurable change of performance
will occur.
