How to Repair a Panasonic Massage Chair, Part 3

Unfortunately, my rubber hose hack from Part 2 worked only for a few weeks. The belt again stretched, and became loose:

One thing you can also see in the photo above is that I’ve slid the motor as far to the left as the adjusters allow (the slotted holes for the two brass screws). I couldn’t bend the motor mounts any more to tighten up the belt, so in addition to the rubber hose shim from Part 2, I wrapped 4 layers of electrical tape around each of the two pulleys:

Amazingly, this increased the diameter of the pulleys enough that the belt became taut. I have tested the chair for a few hours, and this fix seems to be working well. Let’s see how long this hack holds up…

    Bummer. Are we certain the belts are unavailable? Because if YOU can’t find replacement belts, the rest of us are SOL, too.

    You should try lawn mower belts

  • Doug in Oakland, CA says:

    You might see if you can 3D print a replacement belt. Come to think of it, being able to 3D print rubber parts seems to be a lot more helpful than the junk that they typically make.

      This is the most promising source of belts that I’ve found: https://www.encompassparts.com/modelbrowse/MSC/12/3
      They only list the newer models of chairs.. it’s quite possible that the belts are compatible, but I didn’t do any research. The other sites I’ve seen that actually list my chair, show NLA status on all the parts.

      As for 3D printing.. that would be nice if it were possible, but not with the FDM and SLA printers that I have.

        Here’s the part in the black and white movie where someone says,

        “Why not load it up with 10,000 rubber bands?”

        Then someone says,

        “HEY! That’s just crazy enough it just might work!”

    I have a EP 1011 chair and has worked awesome but now as it goes thru the programs it will stop the rollers unless I lean forward enough to let them go again do you think its a belt problem or motor?

    • lincomatic says:

      If it squeaks when it stops working and/or you can still feel the motor spinning, then it’s the belts. If it goes completely silent, it’s the motors. Most likely, it’s a slipping belt.

    Thx for the instruction. Works like a charm now.

  • Sherry says:

    I was going to throw my EP1000 massage lounger to the trash can, when I stumbled over this posts! THANK YOU SO VERY MUCH for the info. I cannot find the belts anywhere though. I guess Ill try the rubber band trick mentioned above to see if that works! Thank you again for the info. Extremely helpful

    Try a sewing machine/vacuums repair place. If you don,t have one locally try a sparge Print from the hardware store they make great vacuum roller belts.
