How to Replace the Front Roller on LifeFitness Next Gen Treadmills

Tools Required:

• Hex key wrench set
• Socket and ratchet set
• Screwdriver set

Procedure:

1. Turn the unit off at the power switch and unplug from the outlet.
2. Take off the motor shroud.
3. Loosen the belt tension bolts of the rear roller to provide enough slack in the running belt to allow side-to-side movement of the front roller. Count the number of turns taken for the slack in the belt. This makes re-tensioning the belt easier.
4. Lift the idler arm to release pressure on the belt and remove the drive belt from the pulley on the front roller. Do this by placing a flathead screwdriver in the slot on the idler arm and lifting it up. You can place a small hex key in the access hole to hold it in this lifted position.
5. Remove the anti-static brush to avoid damage. Remove the two screws holding the anti-static brush bracket to the frame directly behind the front roller pulley.
6. Remove the mounting bolt and washers holding the front roller in the frame. After removing the hardware, you will slide the left end of the front roller as far into the left side of the frame as possible. This allows the opposite side enough room to let the roller clear the access hole in the right side of the frame. Remove the drive motor belt from the pulley. Remove the front roller from the right side of the machine.
7. Place the new front roller in the position of the old roller. Secure it with the bolt and washer removed earlier.
8. Place the drive belt back onto the pulley ensuring it is fitted properly into the grooves.
9. Release the idler arm by removing the hex key and lowering it back onto the drive belt.
10. Be sure to set proper tracking and tension on the walking belt.

This completes how to replace a front roller on a Life Fitness Next Gen treadmill.
