5. Using a fine tip marker or scribe, place a position reference mark on the right hand drive
roller mounting bolt directly in front of the drive roller shaft. The bolt is being marked so that
the drive roller can be returned to the exact same position. The use of a fine marking line
allows for more accuracy when the replacement drive roller is installed.
6. Remove the drive roller mounting bolt from the roller shaft and remove the drive roller from
the treadmill.
7. Remove the running belt and deck from the treadmill. If both sides of the deck have been
used, discard the deck. If the bottom side of the deck has not been used, flip the deck so
that new deck surface is on the top side.
8. Using a clean, dry cloth, wipe the top surface of the deck clean of any dirt, dust or debris.
9. Place the deck, new surface side up, inside the replacement running belt. Set the running
belt and deck combination in its mounting position on the frame.
10. Slide the drive roller through the running belt and drive belt. Insert the drive roller shaft left
end into the doubler plate hole. Hand start the drive roller mounting bolt.
11. Tighten the right drive roller bolt until the position reference mark aligns with the front edge
of the drive roller shaft. The drive roller should now be positioned to the original position
and square to the treadmill frame.
12. Slowly rotate the drive motor flywheel to walk the drive belt onto the roller pulley. Make
sure that the drive belt is fully seated on the pulleys and that the drive belt is correctly
aligned.
13. Slide the replacement Take-up roller into the running belt and set it in its mounting position.
14. Hand start the left and right Take-up roller mounting bolts.
