Video Demonstration of a Belt and Deck Replacement on a LifeFitness 95T Treadmill

  • This video demonstrates the steps necessary when performing a belt and deck replacement on a LifeFitness 95T treadmill
  • Tools Necessary:
    • 9/16" Socket Wrench or 9/16" Hand Wrench
    • Long Flathead Screwdriver
    • Phillips Screwdriver
    • 4MM Allen Wrench or Allen Socket
    • 8MM Allen Wrench
    • Plastic Putty Knife
    • Shop Vac or Vacuum
  • Begin by turning off power at the treadmill and unplugging the unit from the wall
  • Remove the upright tube caps from the inside of the uprights
  • Remove the Phillips screw and tilt the cap in at the top
  • Remove the motor shroud by first taking out all four screws in the shroud
  • Then remove the screws at the top of the front panel and loosen the lower screws
    • This will leave enough play to remove the shroud as shown in the video
  • Now with the Phillips screwdriver, remove the finger guards at the end of the treadmill from each side of the rear roller
  • You will need to slightly twist the finger guards to get them out from under the belt
  • Using the 8MM Allen Wrench, loosen the bolts on each side of the rear roller by 10 full turns
    • At this point, you can completely remove the rear roller bolts while keeping count of the number of turns at each side of the roller
  • Do not include the 10 full turns from the previous step, only count the turns for this step and make note of the number of turns for future referenc
  • Carefully remove the rear roller from the treadmill and set it aside
  • At the motor compartment, use the long flathead screwdriver to lift the tensioner arm and remove the drive belt from the drive motor pulley
    • CAUTION – Pinch Point
  • Using the 9/16" socket wrench or hand wrench, remove the bolt from the front roller mount
  • Carefully remove the front roller from the frame and set the roller aside
  • Use the 4mm Allen wrench or socket to remove the 4 deck bolts from the deck
  • Once the 4 deck bolts are removed, you can pull the deck and belt from the frame
  • Be careful to not let the deck drop too far down into the frame during removal
  • Damage to the anti-static tinsel can occur if deck drops too low into the frame (as seen in the video)
  • It is recommended to thoroughly clean the treadmill before completing your belt and deck replacement
    • While the belt, deck and rollers are out of the frame is a great time for cleaning
    • Dirt, debris or other contamination can cause noise, early damage or premature wear on new parts
  • Use a plastic putty knife to scrape away any debris build up from the front and rear rollers
  • Vacuum most of the painted surfaces then wipe clean with a Sportsmith equipment wipe
  • Once you've completed the cleaning of your treadmill, it should now be ready for reassembly
  • It is necessary to install a new deck surface with the new treadmill belt
  • Your unit may have an unused side of the deck that can be flipped into use or the deck may need replaced
  • Before installing the new deck surface, inspect the tinnerman clips
    • The tinnerman clips are what the deck bolts thread into
  • Simplify the installation process by placing the new treadmill belt over the new deck surface
    • Ensuring the belt is installed in the proper direction
      • If marked, use the arrows on the inside of the belt
  • Now place the belt and deck into the treadmill as a unit
  • Install the front two deck bolts (closest to the front roller) about half way
  • Then use a long tool to line up the deck holes by the rear roller while placing your weight onto the deck to allow the bolts to start
    • Install these bolts in about half way
  • Now tighten all four deck bolts
  • Carefully insert the front roller under the treadmill belt and into place
    • Making sure to install the drive belt over the pulley on the front roller
  • Install the pulley end of the roller into the frame and align the other end with its bolt hole
  • Install the bolt and using the 9/16" socket or hand wrench, tighten it
  • Again, use the long flathead screwdriver to lift the tensioner arm and reinstall the drive belt onto the drive motor pulley
    • Practice CAUTION as this is a Pinch Point
  • Install the rear roller under the belt and while pulling back on the roller install the roller bolts on each side
  • Remember to keep count of the number of turns on the rear roller bolts
    • Reinstall the roller bolts using the same number of turns you noted from earlier
  • The belt may still be too lose, but that is ok as it can be fixed in a moment
  • Plug the unit back into the wall outlet and turn the power on
  • Start the unit at a very slow speed and observe the tracking of the belt
    • If the belt is not turning with the front roller, make small equal turns of the rear roller bolts until the belt begins to move
  • If the belt moves quickly to either side of the frame, quickly press the STOP key to keep the belt from being damaged
  • If the belt is moving to the left side of the unit, you can tighten the bolt on the left side of the rear roller
  • If the belt moves to the right side, you can tighten the bolt on the right side of the rear roller
  • Once the belt is tracking straight, move on to the next step
  • Re-install the finger guards over the rear roller with the Phillips screwdriver
  • With the unit stopped, step onto the treadmill and straddle the running belt with a foot placed on each side of the frame
  • Start the unit at a walking speed and begin to walk on the belt
    • If the belt stops on your foot fall or with your weight, make small adjustments such as 1/4 turns on each side of the rear roller until the belt slippage or hesitation is no longer felt
  • Continue this adjustment until no slippage or hesitation is felt at running speed
  • Now reinstall the motor shroud and upright tube caps
  • Log the repair into the Maintenance record of the treadmill display electronics
    • Press STOP then hold the PAUSE key until the display comes on and reads SERVICE MENU
    • Use the UP or DOWN arrow to scroll to MAINTENANCE and press ENTER
    • Display now reads MAINTENANCE MENU
    • Use the UP or DOWN arrow, scroll to REPLACING BELT/DECK and press ENTER
    • Display will read REPAIR LOGGED and will then return to the SERVICE MENU
    • You can press STOP key to exit the SERVICE MENU
  • This completes the belt and deck replacement on the LifeFitness 95T treadmill
