A. Slide the new drive belt around the front roller.
B. Using a 9/16” socket wrench with a 3” extension, insert the two screws that fasten the
front roller to the frame.
NOTE: Tighten each of the two screws evenly, making sure
not to tighten one screw too many turns before moving to the other screw. See Figure 8.

A. Using a 3/4” socket wrench, tighten each rear roller bolt evenly, making sure not to
tighten either bolt too many turns before moving to the other bolt.
NOTE: Do not
overtighten the belt. You will tension and center the belt in step 23C.

remove the flywheel, screw,
washers and motor (ansi
square) key from the old motor.
See Figure 14.
B. Place the flywheel in position on
the new motor and slide the
motor key into the slot on the
flywheel. See Figure 14.
C. Using a 7/16” socket wrench,
install the flat washer, split
washer and screw that hold the
flywheel on the motor and then
tighten securely (80 in-lbs). See
Figure 14.
Motor Brushes
NOTE: Motor brushes are wear items that will periodically need to be replaced. Both drive
motor brushes must be replaced as a pair. This will ensure even commutator contact
and brush wear. However, the one brush may wear faster than the other brush.
Therefore, always measure both brush lengths to determine whether you should
replace the pair. Check both brushes for cracks or chips.
NOTE: When “ Err9 ” appears on screen it indicates motor brush wear. The treadmill will run
100 miles (161 kilometers) longer and then be inoperable until brushes are replaced.
