i just want to throw it out there that your videos have consistently given me exactly the information I required each time I had a question. At this point I go directly to your channel with my repair inquiries.

I appreciate the lack of standard snobbery. Cup and cone gets the same treatment as ceramic bearings.

These Park tool vids with master mechanic Calvin, are clear, concise, and thorough. No cussing, no juvenile antics, no lousy music, no drama. Good lighting, close ups and a stable camera. Bike mechanic vids just don't get any better than these from Park tool. Thanks Calvin and Park tool!

A major reason is that these cup and cone bearings don't have internal seals and if they even have external seals they are very loose seals, so extra grease is needed to help keep water out. Sealed cartridge bearings range from 30% to 70% packed depending on the rider's use case.

I was complaining about some noise my bottom bracket was doing for almost a year. I respected the takeout so much, i didnt even try to do anything. This Video was an awesome guide and after just deinstalling, good cleaning and installing, the noise was gone!!! Im so proud of myself having this experience and was able to learn how to adjust bearings... was real fun! Big thank you :)

This man need to be presserved....His knowledge is a treasury....

"Cover with more grease," is my new catch phrase.

I always insert park tool in the search bar if ever they had a service video about certain bike parts. Very well explained.🙌🏼

Very useful and detailed video, without superflous commentary, to show how to install and adjust cup type bottom bracket bearings

As a beginner mechanic owe so much to Park and Calvin.

Calvin and Truman are very knowledgable. AWESOME videos!!!!!! Thank you!

This video is just what I needed! I knew my bottom bracket had developed a lot of play and needed rebuilding. I especially appreciated the advice on when to replace the parts.

Completely demystified the process. Fantastic.

very clearly explained, well done, you have saved me a lot of hassle.

Fantastic video. Professional quality. I'll always buy Park Tools as a thank you for these videos.

Thanks for the tip about using the headset press to hold the wrench in place. I'd heard that one a while ago but forgot until I saw this video yesterday, and it came in handy today when I had to remove an approximately 45-year old fixed cup.

I'm thinking of doing a scratch build from a bare frame(custom beach cruiser) so this has been very informative. Both the bottom bracket and the star nut in the head stock(steering column) I've been the most concerned about installing myself.

Thank you very much for this video. I will buy tools from Park Tool.

I love what I am watching This information is very useful to me here in Dubai because i repair my bicycle myself Thank you very much

Perfect. Just what I wanted. Keep up the good work :-) .

Nice explanation Calvin! I'm ordering mine today!

3:30 The HCW-4 tool is quite expensive (£38) but I managed to unscrew the bearing with a large pipe wrench, gripping the two flats. I also had to heat the whole thing with a blow torch and even then it was very stiff, tightening up each time it cooled. It can be done though if all you want to do is bin the old bearing and fit a modern sealed cartridge. Great video, particularly the details of it being a left hand thread.

Thanks man you are a genius this video was inspiaring it helpt me alot. Im ridning a Haro Zimsala Cooper and this was the video that helpt me using the right tools to remove the bottom bracket and more You are än expert

Brilliant video, thankyou.

I typically use a small paint brush to apply grease to parts. And you can spin the shaft on the bearing while holding the cup vertical, to see if the surfaces are pitted. Thanks for the video!

Calvin Jones is my hero

Super wonderful .thank you for your pro job

thank you - very helpful - I still think that a cup and cone bearing which is in good condition feels better to ride than any of the modern stuff - probably because of the 1/4" ball bearings - I prefer loose balls as you can get 11 in - the cages normally have 9 or sometimes even 7 which puts more load on them - of course they do need regular maintenance especially in wet and dirty condition but if you do strip, clean and regrease often they are fantastic!!

8:22 just a very important note. Ive recently gotten into vintage bikes and most appear like in the video but I've done BBs that sometimes have the bearings flipped. To keep yourself from guessing, just take some pics when you disassemble it

Gr8! now I have to find another bike so that I can use the tools which I thought was obsolete lol

I like to replace with a BBUN26 square taper from shimano.

Amazing that I've done all my repairs and parts swap using nothing but a set of Allen wrenches, a flat head screwdriver, a hammer, a spoon and a set of vice grips.

if im planning to completely replace the spindle and crank, what do i have to look out for

Very helpfull. I want to replace my cup and cone with a cartridge, and still use the same crack set. How do I know if it is jis or iso? Maybe am i missing something. I was looking at the shimano un300. Is a 1984 trek 450 series with Sakae Cx cranks. I understand measuring the housing and the spindle length.

Great presentation. Who catered this film?

2:25 are there any Dura-Ace Octalink non-cartridge bearings anywhere in the world that aren't completely toast? Even the pros swapped these out for Ultegra cartridge units. I know, I did plenty. 2:40 addendum: the cups are probably seized into the frame, so get out a punch, a grinder, a 1/2" airgun with sacrificial sockets, a welder and a hefty length of angle iron to try and shift them.

Which lock ring will I have to use with Torue wrench for tightening the BBSet 68 -122.5 MM?

What's the latest kind of system that this system can be upgraded to? I'm in the process of converting a 7 speed mountain bike to a single speed and I have to replace the whole drive system and rear wheel because the rear wheel is bent and I can't change the three chain rings to one chain ring because the rings are all riveted on and even if I drilled them out it still won't work.

A word of warning I had a mountain bike years back unfortunately the 6 pin bottom bracket was starting to get loose from knackered bearings however i couldn't undo it as it was totally seized up tight the 6pins of the bottom bracket tool just sheared off i ended up giving it to the scrap metal guy once their seized its over you will never get it off if you do use plenty of grease when screwing it back on.

My Panasonic Mountain Cat 6500 has this style

Newbie here. I only realized that there are two different sides when I reinstalled the bb. One side is about 5 mm longer. There are no markings on the axle itself. Is there a way to tell which sides goes where?

Can I change this cup and cone buttom bracket with a hallowtech cranckset?

My BB is cup and cone. Non drive side has 26mm bolt, trying to turn it with adjustable wrench, its always slipping cuz the head surface is too thin. The drive side is 36mm round-flat head. My adjustable wrench jaw isnt wide enough, need to buy bigger wrench? Or i have to use tge specific 36mm one?

I did this a few weeks ago, and had a lot of difficulty screwing/unscrewing the cups (had to use a mallet almost all the way). Is it really possible to had grease on the treads? Doesn't it prevent "locking" the screw?

@parktool

4 жыл бұрын

The pre-load or tension in the threads from tightening holds the part secure. Grease permits proper tightening to keep it from loosening. It also helps prevent it from seizing or corroding in place.

I want to convert from cup&cone to a cartridge spindle. 68mm with 127mm and Italian thread. Am I looking at a straight swap when it comes to dimensions? And also the Italian thread thing is problematic as it is more difficult to find the part, so can you recommend me a part or two I can try to find online?

Are these types of brackets most common on budget bikes?

With the frame hanging like that non-caged bearings will drop down into the down tube, better to have the frame hanging from the top tube with the bottom bracket at the bottom.

If the ball bearings are loose, what stops them falling into the frame tubes as you extract the spindle? Is that what the plastic guard is for?

@parktool

7 ай бұрын

That certainly can happen. Rotate the bike so the bb is the lowest. Then they will not travel down the tubes. The sleeve inside is to keep grit from entering through the tubes into the bearings.

How do you know which way to put the spindle in if one side is longer? I didn't manage to note it when removing.

@parktool

Head or Tails. Guess and install. Do not adjust yet. Put on crank and check chainline. If it is rubbing frame, flip the spindle. If the spindle makes the rings stick out too far out, again flip. The middle of the rings should align just to the outside of the middle of the rear sprockets.

The drive is is the "fixed" side, it is not used for a bearing adjustment. If you did use a threadlocker for the non-drive....HURRY! You will need to get it adjusted before it sets up. Then if you wanted to adjust it again any time later, it may prove difficult.

@@parktool Thanks for the reply! I learn a lot from your channel. I ended up getting it (before seeing your reply). Penetrating oil on exposed threads, positioned SPA-1 in notches, slid a cylinder over BB spindle such that it kept the SPA-1 pins from retracting out of the notches, then a clamp holding the cylinder in place using the far end of BB spindle. Once I got it to break free, it unthreaded easily with the SPA-1 tool alone. I like RaceFace products, but that was a poorly designed BB imo.

My knockoff return Schwinn from Wal-Mart did not have a sleeve. Noticed a hole that went from the bottom bracket imto the seat post. So after reassembly. I took the seat post out, stuck my grease gun hose down the tube. Pumped as much grease down there as I could. Eventually I'll get around to making a plunger. That way I can just push the grease down. The bike is mostly used around where I work. So I'm not bothered by this hackery.

There are two parts to the adjustment on that bottom bracket. The cup is threaded in or out to contact or press on the bearings. The lockring is tightened to keep it from moving. Only check the adjustment when the ring is tight. The concept is be right on the edge of play, but still feel no knocking as you check a full rotation of the spindle. It is normal to have the cup slightly press against the bearings, which then press against the spindle. This is called "preload" and is needed in machinery. It might feel like drag to your fingers, but to the crank and you pedals it feels like nothing. We need another video just on adjustment only.
