How To Fix A Slipping Treadmill Belt

Videos like this are part of why I love YouTube. This is a clear, concise, and extremely helpful video. After just a few minutes online now I can fix my treadmill competently. Thanks!

Someone just trashed a 3k Treadmill because of slipping and I just fixed it!!! Thanks

My treadmill is different than yours. You tightened your belt using an Allen wrench. I tightened mine using a socket wrench. Heck, I didn't even know those spots existed on the treadmill. Thank you so much, RJ! I nearly worried myself to death for 3 hours wondering what I was gonna do. Thanks again and thanks to the founders of YouTube! With YouTube, I've repaired a washing machine, a lawn mower, a headlight/taillight in the car and now a treadmill. I feel unstoppable.

NOTE: This product works exactly as described. youtube.com/post/UgkxguEIMc_Qwab-3QMTpF6jaRL80hiOO… It originally earned a four-star review due to a minor defect (see below). However, the manufacturer's customer service rep (Lita) went above and beyond the call of duty and deserves five stars now. I wish I could give even more!I purchased this item which arrived quickly. Assembly instructions were easy to follow. There was only one problem: One bolt did not screw into the hole properly. I called the company. Their customer service rep (Lita) was terrific! She took all my information and submitted a request to replace the defective part. I'm hoping to finish assembly and start using this treadmill soon. (Fingers crossed...)FOLLOW UP: Lita called back to inform me that the company will send a replacement part AND a technician(!!) to install it properly. AMAZING CUSTOMER SERVICE!! Thank you!!

I thought i was too heavy😂

Cheers. Had a new treadmill delivered yesterday, and was slipping right from the getgo. Whoever installed it didn't tighten it up from the box, and I had to give it like 3 full turns to stop it from slipping. It's perfect now.

YOU ARE AWESOME!!! I was ready to buy a new treadmill.  I thought the belt was worn out, causing my slipping. SOOO glad I came across this video.

Wow, I had bought a used treadmill, used it for a week straight everyday for 4 miles, the walking belt started ripping in the dead center. Needless to say I spent $80 on a new walking belt, lost 2 weeks of walking (which I was/am ADDICTED to) finally got the belt shipped and begged two guy friends to help and we didn't have the right ratchet bit, after taking out most all other bolts and screws. Long story short, an hour a day for 3 days (as a girl mostly by myself) got the belt on and was so excited. Turned it on, it worked and finally lined it up and it started slipping. Your video was the first that popped up and wow, WHAT A SAINT YOU ARE!!!! Thank you very much for making this video, I am now a subscriber!!! THANK YOU THANK YOU THANK YOU!!

Man, you saved me big time! I was loosing it when this started happening and considering the quarantine situation it didn't make it easier.

Lifesaver! We purchased a new treadmill about 10 days ago and this started happening from the beginning. As someone in comments mentioned, I thought I was too heavy so that's why that's happening. I looked at the menu that came with the treadmill, zero info on slipping and how to fix it. I thought we will have to return the damn thing and then I decided to look up "treadmill slipping" on youtube. THANK YOU!

Thanks for the vid. I just got a treadmill from a friend and it was slipping. I had no clue what was going on and felt my excitement slipping as well. When you did the arm test and then tightened yours with an allen wrench it blew my mind. I tried putting my arm under the belt and I was able to poke my fingers through the other side! After a couple quarter turns it was perfect. Thank you.

I really appreciate you posting this video! I was about to give up on my treadmill and I love it. So thanks for sharing your wisdom!

Omg, this video was a lifesaver. My wife and I could not figure out why our belt was drifting to one side of the frame. Thanks to this video, problem solved! Thanks!

Thank you! You saved me tons of money with this video. I've had my treadmill for about 5 years and it just started slipping recently. I never even knew you could tighten the belt. Everyone I asked about it told me the only remedy was buying a new one. I tightened the bolts and BAM that did the trick!

I haven't ran on my treadmill yet after tightening it with an allen wrench, but I'm pretty sure this will fix my issue. Saved me an hour wait time on the phone with Nordic Track. Thank You, Great Video!

All this time I thought my treadmill was history....thank you so much for sharing! Fixed it easily and am ready to run again...thank you!!!

Thank you so much. Your videos answered my questions on lubricating, stopping slipping and fixed my squeak. Great!!

Excellent video, we bought the same treadmill shown in your video and from the beginning the belt slipped…and then I happened across your vid and had no idea that it could be adjusted or tightened…now it works beautifully.  Thanks so much!

Sincerely helpful. Much appreciated. Fixed the slip that was giving me knee pain.

Thank you very much for this! It's been driving me insane for ages, this is really useful <3
