How To... Replace the Drive Belt - Continued
Special Tools Required: None
5. Index the rear roller on both sides. These marks will be used
to bring the striding belt back to its original tension.
6. Loosen the striding belt by turning the rear roller adjusting
screws counterclockwise.
7. Move the left end of the front roller shaft out from
its elongated mounting hole and into the left side
of the frame. This will allow the right end of the
front roller shaft to clear its mounting hole so that
the drive belt can be removed off the front roller
pulley.
8. With the drive belt off the front roller pulley,
remove the drive belt off the drive motor and
discard.
9. Install the new drive belt in reverse order. Re-
tension the drive belt, at the index mark, at the
tensioning bolt on the motor bracket. When the
drive belt is properly tensioned (1/4" deflection),
tighten the motor bracket bolts.
10. Re-tension the striding belt to the index marks.
Additional adjustment may be required to
achieve proper striding belt tension. Do Not over-tension the striding belt.
