How To Fix A Slipping Treadmill Belt

I show how to repair a treadmill walking belt that slips or stops sometimes when your foot comes down as you are running or walking. The most common reasons for this are a loose walking belt, or friction between the deck and the belt. It is also possible that the drive belt is damaged or worn out. Or if could be the walking belt itself is worn out. This treadmill is my Sole F85 with over 2200 miles on it.

I just pulled my old treadmill out of the garage and it slips, I will walk for 30 seconds, belt will stop, I get off and the belt runs again. I never lubed it too. Thanks for your videos, I will be following your trouble shooting steps with this video and the lubricating video.

Did u fix it?

[@slipnorris5882]

@@crazyworld3129 I lubed it and the belt ran like normal. It was running for 2 months, I was happy until it broke down again, not a belt issue (something else)

Hi I jus cleaned up my treadmill cuz it was all dusty and put away for years, it's working still but as soon as the belt starts running it immediately stops after like 3 seconds. Idk what the problem is, if u know plz lmk what's the problem so I can fix it thx

Contact the manufacturer.

Wooo just got a free treadmill cuz people can’t google shit! :)

[@rey11able]

NOTE: This product works exactly as described. kzbin.infoUgkxguEIMc_Qwab-3QMTpF6jaRL80hiOOsIN 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’m here for the same exact reason! I’m trying to resolve this so im not paying a treadmill tech to come turn two screws 3 times lol

[@georgemoore528]

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 KZbin! With KZbin, I've repaired a washing machine, a lawn mower, a headlight/taillight in the car and now a treadmill. I feel unstoppable.

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.

[@MrJohnpfisher]

We had a treadmill from Sears for almost 30 years. Of course, it was rarely used. Not once in those 30 years was it adjusted or lubed, but it worked perfectly when ever someone removed the hanging clothes to use it. I retired 6 years ago and starting using it daily. Finally, after 2 years of heavy use by me, the motor burned out. We got a new cheap "AFG" treadmill from Dick's Sporting Goods in Boston. From day one it turned out to be a LEMON. -Constantly pulling to the right and speeding up/slowing down. I did all the adjustments the manual said to do, and it would work for a few days, until the whole process would start over and over again. No one in my family would use it, which was a blow to my ego because I was constantly telling them, "I fixed it." This went on over a year -again because of my ego, so the warranty was voided. Finally, I decided, that THIS ENDS NOW!!! So I took over 2 hours vacuuming it out, applying belt dressing to the motor drive belt, adjusting the motor drive belt, recalibrating the speed, lubing the running belt and convincing myself that it'd work better if I wiped the whole thing down with those alcohol wipes -hee hee-(not kidding). So, I get on it thinking I've done all I can, and IT LITERALLY TRIES TO KILL ME. It immediately starting speeding/slowing and I had to FIGHT LIKE HELL to stay on!!! This was the first time I had to pull the "Safety" plug to stay alive!! I was LIVID!! I was at my wits end, so I decided to find a repairman. The only guy we found wanted $125 just to show up!!! I know he would've just done the same things I did and tell me "it's fixed." It'd work for a few days until it became "possessed" again and I'd even be MORE upset thinking the next step would be to call a Priest. That's when I decided to examine the motor which always seemed fine. I removed it from the chassis......and get this......IT WAS MISSING ONE OF THE 2 SCREWS underneath that holds it to the frame!!!!! So that means all the tightening of the motor belt I was doing was only causing it to pull harder on the left side of the front rolling belt which made it act like a fulcrum and pull the running belt hard to the right over time!!!! And to add insult to injury, there was a SIGNED inspection sticker RIGHT NEXT TO THE MISSING SCREW!!! UGH!!! So now to find a properly threaded screw to make up for the missing one. This was harder than it sounds because it had to be very short so as not to puncture the interior of the motor casing. I got lucky with a hacksaw, but it took a few tries. Sooooo now, everything works great!! The running pad still pulls to the left/right, but I think that's because of all the "rage" tightening I was doing over the years, so I might have warped it. Now I've found if it pulls to the right, just run on that side and it'll go back to the middle quickly.....(pause).....(deep breath).....thanks for listening......

[@jackthetron]

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.

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!

[@more-jays5530]

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!!

Way beyond this video. Probably controller board or sensor. Contact the manufacturer.

[@skypilot177]

Thanks so much for the prompt reply!

[@ГОДРА]

Dont tighten while the motor is running! You can see when he did it, it raised one side of the roller higher and made the belt move to the side with less tension. Turn off, tighten evenly and turn on after.

[@yvetteg6863]

Enjoyed the video and I know this was done some time ago but what do you do if you put to much lubricant and now you belt is slipping?

[@RJTheBikeGuy]

You would have had to put A LOT too much. Wipe some out I guess. That might not be the reason it is slipping. Check everything else.

Belt fraying?!? Thanks for this video. After lubing and tightening and centering the belt, I was feeling quite proud of myself. NOW, I’m noticing the outer edges of the belt seems to be slightly fraying. What is causing this frizzing? I’ve adjusted it as instructed (hand halfway under belt with some effort). Please advise…

Thank you for taking the time to produce your excellent videos on maintaining a treadmill. I need your assistance. I have a Sole F80 and while I’m running (7MPH) or walking (4MPH) every now and then the treadmill will stop then speed up rapidly (Fast) and it will give me an Error Code 5 message on the screen. I’ve been thrown off the treadmill twice and I’m lucky it hasn’t caused me a serious injury. Do you have any idea what could be causing this happen? Thank you.

I flew off my walking pad today😂😂😂. I thought i put too much lubricant.

[@midaslin1475]

My treadmill had this slipping walking pad symptom, tightening walking pads didn’t help, so I opened the motor cover to see how it happen, and noticed when I stop the pad the motor still turning, the driving belt slipping totally. Then I noticed the driving belt seem greasy which causes the slipping, so cleaned up the driving belt (under side), and the problem solved. Not sure how the grease caught by the driving belt, I guess that I might excessively lube my walking pads, and the oil “fly” over during the run. Anyway, in case any one had similar issue.

[@deannaanzevino]

Ugh. I have a used treadmill. Worked fine but it started making a squeezing noise then got a bump in the belt. So I tried messing with the screws like he said. Flattened it out but now it’s slipping.☹️ I really need to figure this out 🙏

[@ivy4559]

Hello! I uploaded a video of my treadmill and the problem I’m having. If you would, please, check it out and let me know what you think. I don’t see any place for me to move the front roller. Every time I tighten the belt the belt pulls to the top left corner near the drive belt. I have spent hours, days, WEEKS trying to fix my treadmill and nothing seems to work. Someone mentioned a “sleeve” to me but I’m not sure what that means. Any help you could give me would be so appreciated.

[@-Rubatosis-]

I can’t seem to fix mine😢 got it 2 months ago, I losed the belt to supply that liquid stuff, but since than I can’t center it anymore. My brother helped me too, but it keeps going left or right, or when it’s in the middle (finally) it went to one of the sides again when walking on it or it slips🫠 I’m so helpless right now, I want to be able to walk on it again. And we have to look out we don’t over tight it and it’s SOOOO frustrating that it just won’t center.

[@anygivenday1]

Thanks so much for this information. I thought we had to get rid of our treadmill.

[@SIRSIG]

Hi RJ. My treadmill would stop intermittently, i know it's not the belt because i just lubed that, i changed the motherboard it improves a bit but still making the same problem. What gives??? You think it's the motor? The belts on the motor are tight. Thanks in advance

[@JanacMeena]

Summary: Tighten using an allen key. If that doesn't work, lubricate the deck.

[@romank2428]

How far would I be able to get my hand under the belt if it is too tight? Seems to be ok at speeds above 4.0. At speeds of 1.0 to 3.0, the belt faintly stops when planting the forward foot.

I don't understand how if you use the 2 bolts to move it left or right that you can then use the same bolts to tighten it... doesnt it just shift the belt...? im trying to get the belt straight and then turn it off and turn both bolts to the right, however it is just slipping again after one use. Advice appreciated!

[@1885ty]

Thank you so much! Such a simple fix.

[@coreadude]

The information in this video gave me the idea for how to fix my slipping treadmill. After I opened up the motor compartment to look at the small motor belt, I noticed that the whole belt and connecting gears were covered in mat lubricant. I assume they got covered with the lubricant when the treadmill was stored in its standing position over a long period of time. After several wipedowns with dry paper towels, the slippage is completely gone.

[@brianzepeda5505]

I just bought mine two days ago and its doing this already wtf. Walmart false advertised aswell super small treadmill cant even run properly

[@salvadorgodinez3830]

My treadmill didn’t come lubricated and it was making my motor work too hard and I thought my fatass was the problem

[@dalesmith7777]

I had a problem with mine slipping and I checked the belt was the first thing I did alignment and tightened it the (walking belt) It turned out it was the drive belt from the motor It was just loose so you break the bolts loose on the motor push it down to tighten the belt snug it back up and it's been fine since.

[@ffaams51]

[@andydowse1234]

Thank you for this video. You might be interested in another source of belt slipping which I have just fixed. I found that both little bolts which connect the drive belt wheel casing to the running belt roller had both come out. Not sure why, constant pounding I guess. Anyway, thanks again. Videos like this restore faith in the usefulness of the internet.

[@tariqahmad4016]

Wouldn’t hand insertion test may differ with thickness of an individual hand ??

I tightened mine as tight as it would turn and is still slipping. This occurred after I lubricated it. Mine is slipping to the right and this treadmill is less than a year old. Not a cheap treadmill either.

[@victoriareese9620]

Hi Thank you for posting this video! I have a Nordic Track C2000 and I did what you stated with the belt tightening, however, I can not get the belt to stay aligned. I can get it aligned for the moment but then once I get on it to run it goes back out of alignment. Do you have any advice? Thank you very much.

Make sure the treadmill is level side to side.

[@victoriareese9620]

RJ The Bike Guy okay...I will try that once we move and see if that works! Thanks for responding so fast!

[@RJTheBikeGuy]

What happens is that the belt runs centered with no weight on it. But when weight is on it, it tends to move towards the downhill side.

[@hiraahmed2270]

My treadmill have same problem and was about to buy a new one. Another problem I am having is the belt (when it wasn't even slipping) goes upwards Instead of downward, if you know how to fix that too please share video.

[@RJTheBikeGuy]

I don't know when the belt would go in reverse. That sounds like a much more serious issue. Maybe control board or something installed wrong. Probably need a service tech.
