LifeFitness Powermill, Replacing All Steps if One Step Broken

Do you have a LifeFitness Powermill with a broke, cracked, or damaged step?

Did this condition occur from normal use? If you answered yes to these questions, you are needing to replace the step. In fact, if 1 step is being replaced, you must replace all 8 steps.

Continue reading to learn how to replace the steps on your LifeFitness Powermill.

It is recommended to have 2 people for this procedure. This part replacement of all 8 steps takes about 1 hour and 15 minutes.

Tools Required:

  • Phillips Screwdriver
  • 8mm Allen Wrench
  • 6mm Allen Wrench
  • Hammer
  • Pliers

Step Replacement Procedure:

Begin by disconnecting power from the machine. Unplug the power cord from the power outlet. Electrical charge can remain in the unit after unplugging. Allow the unit to sit 10 minutes before performing service.


  1. Use the Phillips Screwdriver and remove both the upper and lower side panels from both the left and right sides of the unit.
  2. Pull down on the brake assembly lever and manually release the brake.
  3. Using the Phillips Screwdriver, remove both the left and right inner shroud panels.
  4. Move the stair assembly by hand so that the step needing replaced is halfway down the unit.
  5. Using the pliers, remove the retaining ring on both ends of the bearing shaft that runs through the step.
  6. Take the bearings and washers off the shaft.
  7. Use the hammer to carefully tap the bearing shaft on one end to push the shaft through the step. NOTE: Use an item like the new step shaft to tap the shaft through once it is flush with the chain/step.
  8. Once the bearing shaft is out of the step, the remaining shaft should be removed using the same method.
  9. Install the new step and any new components. Replace any bent or damaged retaining rings.
  10. Put the bearings and washers back on the shaft. If replacing bearings, install the new bearings instead.
  11. Using the pliers, install the retaining ring on both ends of the bearing shaft that runs through the step.
  12. Repeat this process until all 8 steps have been replaced.
  13. Reinstall the left and right inner shroud panels with the Phillips Screwdriver.
  14. Re-engage the brake.
  15. Again, using the Phillips Screwdriver, reinstall the upper and lower side panels to both left and right sides.
  16. Operate the unit at all levels to verify proper operation.
  17. This completes replacing all steps if one is broken on your LifeFitness Powermill.
