How To Replace Worn Treadmill Roller Bearings - Treadmill Repair
Вставка
- Опубліковано 3 кві 2013
- The bearings on my treadmill went bad and were making horrible scary noises. But my treadmill was still under warranty, so they sent me a brand new rear roller. I replaced the old roller with the new one. On the treadmills I had owned, it has always been the rear roller bearings that have gone bad. Looking at my current treadmill, a Sole F85, the front roller is larger and has larger bearings. So I think that is why they don't fail as fast as the rear roller bearings. But since I had the old roller with the worn bearings, I decided to have some fun and make a new video. So in this video, I show you how to replace the bearings on your treadmill. Afterall, when the warranty expires, you are the warranty. I bought the blind hole bearing puller I use in the video at Harbor Freight, but you can rent them cheaper at many places including auto parts stores. The bearings that were on the roller were labelled 6203Z, and the brand name was TMT. I searched for bearings and found many made in China bearings for cheap, but I had also read many poor reviews for bearings made in China. I found some Nachi (made in Japan) bearings on eBay for less than $6 each and ordered those. The model number on these is 6203ZZE. The Nachi bearings had many great reviews and are supposed to be good quality bearings. I am not an expert on bearings, but I think you want to get "deep groove ball bearing" type bearings for a treadmill. And also bearings that are sealed to keep dirt from getting in them.
I hope this video helps you repair your treadmill and keep it going for many years.

You are very easy to understand. I would never had thought that you could replace the bearings and not the entire rear belt roller. You helped me save money on this problem. I am handy but would never had been able to do this without your video. Great comment on buying quality bearings, as many are inferior quality. Thanks!
Great video worked like a charm. I used the axle to remove bearings “pb blaster and rubber mallet” did the trick. Also when I installing new bearing I used a piece of wood between the hammer and bearing as to not damage the bearing. No more noise and saved me $90 dollars thanks again.
An easy alternative to the uncommon tool used to remove bearings is a .5" steel rod longer than your roller from your hardware store. Slip it in one side and tap at the other bearing from the opposite side. Worked great
Great video. This was the last part I needed to keep my 18 yr old True 550ZTX - HRC running. For this model, the rod diameter increases behind the bearing. More effort to knock the rod out, but the bearing comes with it, so purchasing the puller was unnecessary. I used a sledgehammer on the rear, which like other commenters said, caused some mushrooming. A little grinding with a Dremel tool took care of it. I switched to a dead blow hammer for the front, and it worked like a charm. My treadmill took the NACHI Quest 6203ZZE bearings that I got off Amazon. Thanks again!
Thank you! Just replaced mine and I didn't need a puller. I removed both spring clips, tapped the axle through the bearing and used the axle end to knock the bearing back out of the roller. Same for other end.
That's what I was thinking, thanks for confirming its possible.
Very informative video i never opened my treadmill it has gone through lot of hard time. WITH you videos am gona make it good as new again. Thanks you saved me from buying a new treadmill
shyflirt1, I just replaced the bearings, using your instructive video as my knowledge base, in about five minutes. The new ones are now at work on my treadmill's front roller and the machine is as quiet as the day I bought it, new. Not bad for a five year old machine that gets daily use of about an hour per day. The only other thing I've ever replaced on this unit is the circuit board.
Even better than your video on replacing the whole rear roller--thanks so much, tenfold!
Excellent advice! Our treadmill (Sole) sounded horrible and I suspected the bearings. The treadmill was still under warranty, so they sent us a brand new rear roller which we replaced. But after I saw your video, I understand that we probably will get problems again due to poor quality bearings. So next time we will follow your advice and replace the bearings with some that have better quality.
Greetings from Sweden :-)
After I installed some good quality Japanese bearings, I haven't had any issues.
Just completed doing this on the front roller saving a bunch of money. Thanks for the great tutorial. Similar to others I used the back end of the axle to knock out the bad bearings.
Doing this on the front roller is the same as the back, in that the pulley isn't in the way at all? Thanks.
@@rgraz4929 IIRC it is essentially is the same, the motor belt connects to the front roller so I made sure to measure and reposition the roller exactly as before to not have to adjust the tension.
This is a great video. I'm somewhat knowledgeable, but didn't know the first thing about what'd be needed to replace the bearings on a roller. Great alterantive to full roller replacement, assuming I can disassemble. But no matter what you've shown me what's involved.
Great video! Thanks for posting. Was able to replace the bearings too on our F85. Night and day difference.
You can try a little penetrating oil. You can get another rod and tap it down through the first bearing. One you get it through one of the bearings it will probably go through the other one easier. Be careful hitting the end of the rod as you don't want to mushroom the end of it. If it's tight, use a wooden mallet, or cover it with a block of wood and hit that with the hammer.
Very helpful video, thanks. Like others, I was also unable to get the bearings out with a puller. I ended up taking the roller to my local auto shop where they were able to remove the old bearings and install the new ones (Nachi). The noise reduction was quite significant - probably better than new.
They may have been glued in with something like Loctite Red.

Hello sir. You are really good in your explanations with the necessary details. I will be in touch more often. Thank you very much for your videos and keep going with mores.
You Sir, just saved me a couple hundred bucks. THANK YOU VERY MUCH!
Awesome video. Very well done. You need to go to Hollywood. This helped me a lot. Thank you.
I admire people like you with these skills! If I did it myself I'd totally pull a homer simpson and end up saying "why doesn't mine look like that" =(
I did this repair put the thing back together and wonder how a lamp became an integral part of my treadmill ;)
well done here. perfect for my techs to get handle on this process
your videos are very informative and clear. Thanks
you da man RJ, always great instructional vids!
Very cool! Congrats!
Good Video. Just a couple of things.
1 Never use a hammer on the end of a shaft. the shaft will mushroom over. Use a Mallet or wood between the hammer and the shaft.
2. NEVER NEVER EVER use a hammer on a bearing. Again use a mallet or a brass hammer. I've known people to be suspended for that
Blueman, very true!!! Great tip!!!
Thanks!
worn out rollers produce sound and you can hear it clearly by listening closely. The sound is same with or without a person on treadmill
Thanks for the video, looks like this will help me fix up my roller pretty inexpensive. I've had a load of problems this winter. First a new deck (under warranty), now the bearings need replaced, a bolt snapped off from a mystery location, AND three of the shock absorbers broke loose..... Hopefully in a few weeks I'll have one less problem than I have now.
Ouch! What kind of treadmill do you have?
It is a Sole F80, purchased December of 2010, with about 1750 miles. I am a relatively fast runner for 190 lbs., so they have been hard miles!
Sole has good customer service. I have a Sole F85. Currently a little over 2000. Sole sent me a whole new roller which I installed in another video. Then for fun, I took the old roller and installed new (maybe better quality) bearings in it. I actually have the old roller installed in my TM now, and the new roller saved away.
shyflirt1 Do you have the EBay link or part number of the Naichi bearings you installed? I just checked, and I also have the same original bearings, so I figured i'd just get the same replacements you got.
Search eBay for "6203ZZE Nachi Ball Bearing".
And I recommend always having a roll of toilet paper in your tool bag for when you're messing with grease and bearings, it's excellent, very useful
Thx, changing tomorrow my, so this helped a lot to see in practice how to make it.
The best bearings for treadmills are those with a contact seal, suffix LU, XLU I think, one side X, metal and the other side rubber, the LU, the rubber contact seal better isolates the bearing humidity, which is one of the main causes of failures in treadmill bearings
One of the bearings on my roller had snap rings on both sides of it making if much more difficult to do this, and I didn't find this out until I'd gotten it out. I had to use a sledge hammer to whack the axle bar and bearing out together. In doing so it mashed the end of the bar I was whacking, enlarging the diameter at the very end which made it impossible to get the other end of the bar out of the inner bearing. I ended up using a bench grinder to reduce the circumference at the tip of the bar. The extra snap ring on the inside of the bearings I've now removed so I won't have this issue next time.
Great video! But... my treadmill is a Star Trac, and the rear roller (tail roller as they call it) does not have a visible C-ring that can be removed. There's a black cover flush over that area that I cannot figure out how to remove. 3 tiny holes around the diameter of the outer roller probably release the cover or the axle somehow, but I don't know what tool I need to "activate" those either. Ideas?
@RJTheBikeGuy do you have any advise how to get a stubborn rod out? Is there a tool or are you just supposed to hammer with a much larger force I felt comfortable with. I have tapped it quite a bit with a mallet, but it does not move much. The bearings still feel smooth once the roller is out, but after 7 years of really heavy use I thought it was time to take the noise coming from the rollers by replacing the bearings.
thank you so much for sharing
What if I put ceramic grease-free bearings on -- will this put less strain on the AC motor? The bearing removal tool is dope, great to know!
Big thank you
thanks a lot... Your video is great...
I have noise in my life fitnesses 95 ti treadmill I notice some from the idle pulley I been thinking to replace all the bearings any advice
Wow. Great vid. I own a gym but and was getting tired of paying an arm and a leg for my cardio to get fixed. I am going to harbor freight this weekend to get the puller. I took both front and rear rollers out. Any suggestions on how to get the inner rod out if it is very tight in the bearings? I can pound it with a hammerbut once the one end is thru the first bearing how would I get it thru the second if it doesn't slide out? I guess maybe put the inner ring in a vise and pound the roller?
tsaipod Take the C rings off first. Tiny little clamps shaped like a ‘C’. Special tool needed.
Many thanks for the video! I followed all the steps. It was so easy in my F85 that I decided to do the front roller too (I bought extra Nachi bearings). But the bearings in the front roller seems to be completely stucked.
Anybody knows if I should be able to pull them out? I have a puller but I don't know if there's glue or something I miss.
Any tips on how to remove the bearings without that tool? I'm thinking anchor bolts should work, using the roller shaft and a hammer to hit the anchor bolt from the inside after it is in place. But since anchor bolts this size are not that cheap and I would have to use one per each ball bearing removed, I'm trying to come up with another idea.
+Yuri Ramos You could try using the axle as a ram and hit it from the inside out.
hello and thanks for the great informational video.. I have purchased a 12 year old Image 10.0 treadmill and weight limit is 250 and I weigh 250-245 on different days.. Well the tread mill wont turn good when i start to walk on it but if i put it on high incline setting it works good..do you think I should replace all bearings and walking belt? I have not noticed any slipping from the motor belt. I tried justing walking belt and lubed the underside of the belt...any help thanks...
+Duane St John Did you check the drive belt? Either the motor isn't turning. Or the drive belt is slipping, or the walking belt is slipping.
yes i took the cover off. The drive belt isn't slipping but noticed the belt must have been replaced because it is smaller then the pulley.I have also noticed that when i put it on maximum height incline it works good? so idk...
Very good advice about not buying cheap Chinese bearings they are terrible
where did you buy those nice bearings?
eBay. Your TM may use different bearings. Look at the model numbers on the bearings in your TM and then try to find similar bearings. Avoid chinese bearings as the quality will be suspect. I read good things about the Nachi bearings before I bought them.
Would this work with a star Trac treadmill
I am having hard time getting the bearings out. I have the puller from an auto parts store. Im using a great deal of force on the puller but the bearings are not budging. My treadmill is a nordic track a2550 pro. advice? more force? perhaps nordic track roller bearings not removable?
10lb puller or smaller? It's possible they used something like loctite red. www.us.henkel-adhesives-blog.com/post/All-About-Threadlockers/How-to-Remove-Red-Threadlocker/
OEMTOOLS 27128 Blind Hole Puller Set. The listed item weight is 7.5 lbs.
Okay, so it's not a 2lb puller or something. You might trying heating the bearing and then pulling it. Alternatively trying chilling the bearing with dry ice then pulling it.
Ok so i took it to a shop and he put some heat to it and bam they came out. Treadmill back up and running smoothly. Thanks RJ.
Cool!
hi
will bearing sit appropriately if i shorten the roller by cutting it with disc? or there is a special place at the tip that will be lost?
i mean, will bearing sit along any part of the roller or it is different at the tips?
thinking about some diy project.
thanks
Generally, you won't be able to just cut the end off and slap a bearing on. I think many rollers are basically aluminum cylinders with caps on the ends to fit the rollers. Or they might just be machined tubes. You will have to play with one.
@@RJTheBikeGuy many thanks sir
Any tips for finding out what bearings I need? Got a Proform Crosswalk Fit 415. Contacted Proform, but no luck so far.
Pull them out and look for numbers on them. Or measure them and find matching bearings.
Thnx. already figured it out myself. cheers :)
Middle 6th foot belt roller bearings needed to replace except first one, how it can be done
We just got ours and there is a squeak every time your foot hits the deck when running ; notice especially if running a little further back on the deck. It’s like a plastic squeak and I can see a little bounce in the deck. Could this be a bearing or issue with shocks? Maybe I need to put a little shim under the mat on one side?

Where did you but the bearing from? Thanks!
Ebay.
What type of grease do you use when installing the new bearings?
I like marine grease.
@@RJTheBikeGuy do you think a little lithium grease would work as well?
@@davefisher4888 I told you what I use. You can try whatever you want.
Loctite would be better, lubricates when installing and locks the bearing in place afterwards. Grease may allow the outer race of the bearing to turn in the roller.
this was very helpful, thank you. I did a couple of things differently: 1) I bought a cheaper bearing extractor from amazon for $34 www.amazon.com/gp/product/B016W8GSQ8/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1. But, this didn't work for me because the bearings on the roller were super tight (yes, I tried heating it for 2 minutes with a propane torch, still wouldn't budge). So I cut off the head on an old golf iron that I had, leaving me with the golf steel shaft. This fit in the hole of the bearing, so I used this to bang out the bearing. Worked perfectly.
How can I tell if it’s the back or front roller? My treadmill is loud and I think this is what needs to be done
Well the noise comes from the front, or the back.
RJ The Bike Guy ah good point
Please tell me how to disassemble and replace the bearings in the P.MD.C. treadmill engine. motor model A17225M063
Contact the manufacturer.
how i know if the bearings need to be replaced or not?
i bought used treadmill
worn out rollers produce sound and you can hear it clearly by listening closely. The sound is same with or without a person on treadmill
Popping sound as the bearings intermittently lock and are forced to unlock. Or a loud crunchy sound.
can some one help me figure out why the berings instaled keep on braking ? could it just be because of the brand?
Could be cheap bearings. Could be belt is too tight. Could be normal wear and tear. The Nachi bearings I installed are still going and have outlasted the original bearings.
RJ The Bike Guy, do you know someone local to SF Bay Area who would offer their services to replace bearings on my treadmill? Great video but would appreciate professional service.
+phxstar Sorry, no I don't.
You need a rubber mallet lol
Wow! So much better than the mumble mouth guy in the other video. You do a great job of explaining how the procedure is done. I honestly don't understand why the other guy even made his (basically) useless video. Thanks!
What is the size of these bearings?
I don't remember. Unimportant as you need to match the bearings in YOUR treadmill which may no be the same size.
@@RJTheBikeGuy thank you for replying. I see that you already write the necessary informations on your description. I see that your's and mine are the same bearing.
I'm doomed, I will never be able to do all of this to replace my roller bearing on my treadmill. Wow, seems too complicated for me! I'll have to call a professional.
Tanfel Eli crh
ioopi
Bad practice to hit the new bearing with a steel hammer. Use a block of wood like someone else suggested below.
If you tap on the outside part, it doesn't hurt the bearing.
Dude you're breathing way to hard, you need to get to a hospital fast
Dude, the camera is next to my face.
Thanks!!!!
