How To Overhaul A Bike Bottom Bracket - Remove/Clean/Install New Bearings
ฝัง
- เผยแพร่เมื่อ 17 พ.ค. 2013
- This is how to overhaul the bottom bracket on an older style of bike before they started using sealed bearings. I show you how to remove and install new bearings as well as how to clean all the parts. This bike is a 1984 Schwinn LeTour Luxe, but most vintage bikes are similar. They might require slightly different tools. The fixed cup on the chain ring side on this bike has left handed threads. This is the most common. But be aware that Italian and French made bikes might have right hand threaded cups on the drive side.
The spindle on this bike has nuts that press and hold the cranks arm on. Some bottom brackets have bolts. It's a minor difference though. The process is the same.

This “thank you” is long overdue. Over the years I have learned, when I hear or feel something “not right” while biking, to make a mental note to “check with RJ The Bike Guy when I get home.” More often than not, you have “been there, done that,” making my repair job easier and less intimidating. Thanks, RJ.
I like the servicable bottom brackets better than the "upgraded" sealed BB's because instead of replacing the whole thing, you can just replace the bearings.... cheaper, less waste, adjustable.
As someone who used to do this servicing on my bottom bracket years ago and now suffers from ocd, it is a pleasure to just install a sealed cartridge bearing bottom bracket like Philwood. No more doing this every 6 months or so.
Just a heads up when you were removing the fixed cup, if you were to flip the crescent wrench the majority of the torque is delivered to the solid side of the wrench as opposed to being applied onto the threads in the adjuster.
Other than that thanks for the vid, taught me quite alot.
Cheers.
Well Filmed and Edited: Kudos for a clear video (without distracting music) God is good - John 14:6
Explanations and the views are very clear. I have maintained mine with purely the help of this video. I didn't have a crank puller but the cranks came off very easily. Also I couldn't take off the chain side bushing (fixed cup?), so I took of both bearings out from the non-chain side and cleaned everything that way. All in all, it worked! Many thanks!
Great video. The only thing I would add is about loading the caged ball bearings with grease. It's good practice to force grease into the cage by slapping, or pressing the flat side of the cage into a good dab of grease on the palm of your other hand until it comes out of the top side of the cage, working around until the cage is completely loaded with grease.
Agree.
Agree
Thanks for another excellent video RJ. Your uploads are always where I go to first for any queries I have about my bikes. Even the staff at my LBS doesn't know some of the stuff that you cover. Keep up the great work!
Great job on the video. I had put mine back together and wondered why I still had a wobble after replacing, you made me realize I probably have my bearings in backwards. Thanks!
Awesome video. I wish one of the handful of people who vote thumbs down explain their reason. I don't see how anyone came here to learn how to overhaul the bottom bracket but was unable to because of the quality of the video. Once again RJ has helped me with bike issue
I might have some kind of idea cause the the crank puller it specified to use ripped the threads out of my 3 piece crank instead of taking it off pretty well destroyed it
@@joelrandle1972 that's a problem with your messed up crank not the puller. Everybody and their cat uses a crank puller to pull cranks.
You make it look easy! Thank you! This is a project I have been putting off for months. I have 6 bikes and have done all sorts of things to maintain them, but have stayed away from changing bearings. Again thanks, great video.
Thank you for the excellent walk through. Used this video years ago to overhaul my bb. Now years later on another bike found this video again by chance. Saved me the trip to the bike shop and now I’m making sure to save your videos and subscribe! 😄
As the owner of a trusty, rusty 1986 Schwinn World I find this very useful information. Thanks for sharing!
U have the greatest bike channel on TH-cam thank u and keep up the great work. God Bless.
Great video!
Once upon a time we did this to my old mountain bike (cheap one). Your bearing cages look good. Mine were pretty crappy, very thin metal plate, which broke and filed the axle, had to be discarded. So we decided and put new bearings without any bearing cages, which was very smart decision. We put more balls, because of the intentionally missing cage, so that there is a tighter fit. They were held together by the grease. Then put everything back together and it was rock solid, never broke again. Problem is these bearing cages, you can also skip them, by putting more balls, this way the bearing cannot break, much more solid.

By far the best video on maintaining/changing your bottom bracket on the internet. Thanks :)
What a great video! It's easy to follow, thorough, and goes by at a good pace-not too fast for me- I am so grateful!!!
I was looking for a video about how to service the BB on my 1984 Schwinn Le Tour, looks like I found it! Good clear and concise video, thanks.
Schwin are shit
I am clueless when it comes to the mechanics of my bike so these videos are excellent for me :-)
Hey man - thank you for this video! I have been burning through videos looking for a bike like mine to learn from. That fixed whatchamacallit was killin me. Thanks again!
Another good video RJ- you seem like a really nice guy and some of your videos are great- you are really organised and thorough and don't skip little steps like others- don't worry about people who give you any shit on youtube or are sarcastic or smart arses you seem a really nice genuine guy to me. 27 Years riding for me so far still learning mechanical stuff all the time thanks for the videos Boss
Ja. Really good. My giant * worn out bearings also. Good video to explain. I gotta get this to the bike shop guys.
Fourteen year old bike had some very east nuts and bolts coming off
You make very good videos! Not a lot of wasted time, easy to follow, good picture. Clear audio, a lot of posters could learn from you! And yes I am fixing my bike. Thanks for sharing.
Thank you! I've been trying to find a decent video of how to do this properly. With your video, it was explained! God bless 🙏
Just finished a Sugino bottom bracket from an 80's mtb. In this case the adjustable cup required a small pin spanner instead of the hex flats. I got by with a big snap ring pliers and it worked in a pinch. Thanks for all of your tips!
Good vids man! Watching your vids helps me repair my own bike myself! Keep up the good work man!
I want to thank you for making this video. I overhauled mine and it didn't work, you showed me that I put my spindle in the wrong way and installed my bearings the wrong way too. I fixed it and it all came together. Thank you!
Thanks for your video R.J. I wouldn't have been able to get my bike fixed without your video. Thanks again, JCM.
Thanks for the video! Very helpful! You have helped me repair 3 bikes now. My whole family is riding great bikes for the cost of bearings and grease!!
Old vid but very nice. I was able to change my bottom bracket thanks to this. Great quality vid with great explanation.
I learned something new today. And you explained it, step by step, in great detail. Thank you! 👍🏻
What a clear and beautifully explained video! Thank you so much!!!
This is just what I was looking for. I'll make a start on my bracket tomorrow. Thanks!
Such great videos you go into a lot of detail and take your time it really makes a difference to us who arnt novices but still have a lot to learn :-).Thank you and looking forward to more videos .
Excellent step by step explanation. Concise and straight to the point.
Awesome video, my favorite bit... "I'm gonna stick my parts in here" :)
Very clear step by step instructions -- very satisfying - thank you -
Excellent video along with great detailed commentary. A great help. Thanks for taking the time to do this!
Thanks for the video. My bike is getting a little grindy in the bottom bracket but I haven't pulled one apart in well over a decade. Great refresher!
Thanks for the great video helped me get my sons bike going again in no time.
Thanks for taking the time to post this. It's just the info I needed!
Excellent, just what I was looking for! Thank you.
I appreciate this, I'm adopting an abandoned bike to rehab and later commute on so this is really helpful,
Omg thanks so much! I was willing to pay the $50 to fix it. But doing it was so simple. I appreciate the video man.
Thank you for the excellent tutorial. Clear & precise. Much appreciation sir.
this is the kind of thing that makes a great first "mechanic" job. very basic bearings, grease and adjustments, most of us start this stuff at 6 or 8 years old but it is never to late to get started learning.
The only thing I knew how to do was change the tire and inter tube I'm new to everything else I use my bike everyday for transportation to go to work I had to learn how fix my bike when ever something broke down on my bike
Getting ready to do my 1972 Paramount with the Campagnalo 3 piece crank, this video has been helpful, thanks
thank you RJ. Your videos are very helpful.
This is exactly what I was looking for. Very well done. Thanks
Excellent video!!!!!!
This is the perfect step by step instructions & good filming so that it could be followed along. Thank you for this, it has helped a lot!
This looks almost exactly like the bottom bracket on mine. Thanks for the detail.
Thank you - very informative
Great video! Very detailed, thanks for taking the time to make it.

RJ "Imma just go head" The Bike Guy :)
Will definitely be soaking tools in paint thinner from now on. Good tip.
Hello from Scotland, your videos are really good and thanks for the tips how to fix parts on bike !
Excellent video, thank you!
Perfect. Was just doing this on an 87 Schwinn Le Tour - thanks for this...the whole which way to turn wrenches was driving me nuts till I found one of your vids (and I've seen a lot of them before - between you and Bikeman4u. Thanks!
Excellent step by step video
Very helpful, thank you!
This is a square taper bottom bracket. Pretty much standard on older bikes. Yes, you can upgrade to a different style. It gets a little tricky. You will need to figure out the correct length so that the chain line is correct. If you get one that is too long the chain rings will be out farther and the chain will be slightly diagonal in stead of straight. Same if you get one that is too short and the chain rings may hit the frame.
Thanks a lot for your presentation.
Another excellent informative video from RJ. Detailed description and well explained
Nice instructions- thanks!
good stuff man!!!! thank you for sharing.
i m speak spanish but you are the best master mechanic.... very illustrative.. you are the best.. God and bless
Very professional I am building a motorize bike with a centrifugal clutch I have to change the chank axle to keep the pedals from hitting the centrifugal clutch housing this video helped a lot thanks
An excellent video. Thank you!
Thanks a tonne RJ!
Thank You so much. Helped me a lot.
Great video! Loved it, learned from it...Thanks!
Very useful, thank from Chile!
Awesome video mate. :) keep it up!
Great video, thanks for the help.
Hey Shyflirt1 Thank you for all your excellent videos really helpful, You really helped me with my old vintage bike thank you
Excellent!!! You deserve beer from me!
This is a great video! I used to be an electrician, so I am pretty good with my hands, but I am a hands-on learner. I never had anyone to show me and teach me about bikes, so getting it in my head is the hardest part but I am pretty good at executing. I literally watched this video, went and got a crank puller, and completed nearly all of the steps. My bike had a sealed cartridge instead of separable bearings and the plastic part. I had, stupidly, put some grease on it a while before which one guy who fixed the axle in the back of my bike said I should clean off as it would cause problems, but I did not know how to get in there and clean it. Enter your video! It, as I have had it about 5 years without providing it with maintenance nor riding it much, was making a weird sound from the crank, so I took it apart, cleaned it, sprayed it with WD-40 and put it back together. It reminds me of when we had to do shut downs of commercial buildings and we had to turn off all of the switch gear and basically, overhaul it to make sure there was conductivity between terminals et cetera. What I am saying is, thanks!
I want to do my bike now! Don’t even have the tool but who cares! It looks fun!
Thank YOU for superb video well detailed a new learning today, keep it up
thank you for your wisdom sir.
Thanks for your video Homie.
🇺🇸🏁🇺🇸🏁🇺🇸🏁🇺🇸🏁🇺🇸🏁
This video is exactly what I have been looking for, The crank comes off a tad differently (it's a 'cotter pin' crank ) but the BB removes the same way- I have the same problem as stanly manly, in the comments below- I don't have a plastic cylinder, but I'm sure I can either find one or upgrade to a sealed cartridge like in your other video, thank you very much I'm sure your videos are helping many old bikes get restored and back to their former glory :)
Yours might be more similar to this Raleigh. Bottom Bracket Overhaul On Vintage Raleigh Tourist Bike
Good Job, thank you!
perfect, very helpful. not to mention that is my exact bicycle.
soo much easier when You have a crank puller, never had one.☺FanTom
How did you get them off the crank puller I bought ripped the threads out instead of pulling it off
Ive got an old Schwinn World that I need to do this to. It's leaking a bit of what looks like oil and it's making some noises. This didn't look too hard, with the right tools, thank you!
Thanks, I've only seen this done once when I was a kid, so I wasn't sure exactly how to do it. Turned out one of the crank arms on my bike was completely seized on the shaft. I was at least able to get one side off to get enough access to it off to clean it with a pressure washer and re-grease the bearings. Thankfully the side with the seized shaft had less wear, and I had some spare 1/4 bearing balls to replace them on the one side that I could.
I might have been able to get it apart if I had a hydraulic press, I did try a couple other methods including a torch, a hammer/punch and a joint separator, I might have been able to get it apart if I kept at it, but I was at the point where I likely would have damaged the shaft, the bearings or the crank arm so I stopped.
Thanks rj! I didn't have any paint thinner so I used some La's totally awesome cleaner and my 1989 raleigh mountain bike turned out great.
That works too, just slower.
thanks! finally know how to fix it now :)
Thank you very very much sir ...it helped me a lot😍😍✌️✌️
Thanks for share your works
Nice video helps me alot
Thank you so much!
