9. Reinstallation is the reverse of
removal. Before tightening the
tension in the poly-v belt, make
sure that it is centered correctly.
If misaligned, wedge a
screwdriver blade between the
face of the brake and the belt
while turning assembly to align
belt to center of idler pulley.
10. After brake assembly has been
aligned and tension set, attach
speed sensor tape (Item 71) to
the left edge of the brake
armature. First peel off tape
backing on the end with the wide
silver band and stick on the brake
surface hanging down. The tape
should be on center with the
speed sensor. Slowly rotate the
brake upward and wrap tape
around the circumference of the
brake.
11. Temporarily install the crank
hub/bar assembly. Perform the
following steps 12 through 16 and
perform the alignment,
(Procedure 3), if indicated results
are not attainable.
12. Plug in and turn on machine but
don’t press any buttons. The
display will be scrolling the
message, “SCIFIT…” Slowly
rotate the crank arm assembly
and the message will change to a
programming prompt. The
following values will be displayed:
[20.00] in TIME, [0] in RPM, and
[4] in LEVEL. If the display
doesn’t default to these values,
perform Procedure 3.
13. Press the START/STOP button
once and press the SCAN/HOLD
button to hold the RPM function.
Press and hold the DOWN
ADJUST arrow until 0.0 is
displayed in the LEVEL window.
14. Rotate the crank arms at one
revolution per second and ensure
display accurately reads about 60
RPM.
15. Press and hold the UP ADJUST
arrow button to the maximum,
level 22. Rotate the crank arms
as rapidly as possible. Brake
resistance should become
increasingly difficult momentarily.
Procedure 5 – Tightening the
Poly-V Belt
1. Loosen the ½-20 nut that fastens
the brake drive pulley shaft (Item
57) to the main frame.
2. With the nut still on the shaft, use
a hammer to knock the entire
brake drive pulley assembly away
from the brake assembly (Item
68).
3. After knocking the brake drive
pulley shaft a few millimeters
away from the brake assembly,
tighten the set screw (Item 67) so
that it butts up to the brake drive
pulley shaft.
4. Tighten the ½-20 nut that holds
the pulley shaft.
5. Check that job is complete by
rotating crank handles. If there is
no noise due to belt slippage, the
job is complete. If noise persists,
return to step 1.
