  • Flip the frame upside down
  • Verify the chain only goes around the sprocket while feeding it toward the rear of the frame
  • Feed the chain through the traveling pulley from the bottom and around the pulley as shown
  • Make sure the chain is not twisted around itself or the shock cord
  • Feed the chain toward the front of the machine and install it around the pulley bottom side first
  • Make sure it is not twisted around itself or the shock cord
  • Feed the chain back toward the rear of the machine
  • Install the connector pieces as shown to the chain
    • They install in opposite directions
  • Install the chain to the traveling pulley with the nut and bolt removed earlier
  • Connect the two SCAM pieces to the axle as noted earlier
  • Again, Verify that the chain and shock cord routing is correct and not twisted or overlapping
  • Install the return mechanism cover
  • Upright the frame
  • Connect the frame to the monorail
  • Test the rower
  • If the shock cord does not return verify the shock cord path and the chain routing is correct and make sure both are on all the pulleys
