Another quality video clearly explaining the process. Calvin is a legend!
This video really helped me with replacement of two old square taper spindles by cartridges. The comments on care to avoid crossthread, use of threadlocker & grease, & torque were especially valuable. One lesson learned - The BB shell of older and cheaper bikes may be out of round, complicating the process of installing the cartridge.

You should get an Oscar for the best instruction videos on the internet. The world would be a better place if all companies would so clear + concise about their products and how to use them!
Thank you very much for this concise, yet thoroughly informative video! I was able to tune up all the bikes at my house with basic tools. You’ve saved me a bunch of money and the bikes are better than ever!
This video makes me want to personally thank the people who made it. Not many videos do that.
Thanks guys for all the help. I've decided I needed something to stay busy bought an gt avalanche needed some love with the help of you guys and Bermpeak I've been able to learn something different buy kinda the same. Cheers.
High Quality Video. Many thanks for the good work. This is why I always try to buy ParkTool products.
Wow, thanks about the turning directions. I was struggling to turn counterclockwise on chain side in order to disassemble it and before making any mistake I said: let’s check youtube
This channel, and Calvin in particular, has been an amazing resource. I have learned to do virtually all the basic maintenance on my entire family's bi,es and install a new group set on mine. However, the Park Tool threaded bottom bracket tool (BBT-32) was a fail, mainly because the Shimano bottom bracket drive side was poorly cast and the tool wouldn't stay on - a competitor's product had a piece to hold their tool on and it and finished the job in less than a minute. The existence of said tool and recommendations across the internet imply that this is a common problem.

My crankset broke and I'm learning how to replace the bottom bracket with it as well. Thanks for having so much information online. I disabled add blocker to try and support the channel somehow. Keep up the great content!:)
this helped me fix my E-bike bottom bracket, incredibly useful.
To prevent cross-threading the cartridge, one nice trick is to install the hollow cup (left side) first hand-tight. Then install the cartridge from the right side, so it will automatically center when it goes through the hollow cup on far side of BB, thus preventing cross-threading. Then back out the hollow cup, tighten the cartridge, then the hollow cup. This tip from Sam Tracy's "Bicycle: A Repair and Maintenance Manifesto, 2nd Ed, page 159.
Here's a tip for when the old cup is really stuck, on a bike with cartridge bearings and square taper crank fitting: put the Park Tool in place and put a bolt (M8 *fine* x 40mm) through it and into the thread for the crank retaining bolt. Tighten this hand tight and then put a 32mm deep socket on a breaker bar over the Park Tool. You will be able to crack the cup unstuck and once it's moving a bit you can slacken off the retaining bolt as the tool will now be in much less danger of slipping out and damaging something. This has worked for me in the past, though if the cups are *really* badly stuck you may have to resort to the heavy brigade - angle grinder and drill.
These videos fill me with alot of confidence thank you
Clarifying, as always. Thank you!
Excellent instructions
I saved this great video for future reference. THANKS for all the help. Now maybe, I'll remember to pick up some tools from ur website.
Thanks - Really Helpful And Clearly And Simply Explained :D

Best BB explainer vid 👍
These Park guys keep taking my money ...
Very usefull video like many others in this channel. 👍
Thanks Calvin! Trying to see if I can upgrade my old cartridge BB with a hollow-tech version of lighter weight.
Thank you for the detailed explanation
Good video. Thanks for pointing out all the variables (length, dia, threading) of the components I need to replace. Now I just wish I'd watched the video *BEFORE* disassembling the BB. When I was cleaning the spindle I noticed that one side was longer than the other. Now i don't know where the longer side goes. I'm guessing I'll notice a difference in the clearance between the crank arms and chainstays when I re-assemble.
Excellent reference 👌
Thank you, I have a Steel Frame that came with aluminum Bottom Bracket Cups, after 6,000 miles all year riding in Michigan, the cups were eaten away on both sides, I put them back together with Anti-Seize compound, electrolysis is a big problem not mentioned, With Alum/Steel electrolysis a probem, grease works ok, but I have more faith in anti-seize, I owned semi trucks for many yrs with alum wheels and steel lug nuts, if you didn't anti-seize them you payed for it when it was time to remove the wheels. its not a lube, its water soluable, it can stand temps up to 1800 degrees, great for automotive/big truck exhaust. lubes don't do that, bikes don't get that hot, but they do seize. Happy Trails
Thanks for mentioning the 'Cup and Cone' bottom brackets straight off the bat buddy. I didn't even know what that type is called. That's the type I'm trying to learn about. Nice one fella.
Really useful thanks!

Great instructions. To may different tools, Industry needs standardization for the components and frames. Just like the auto industry.
I could not get my Shimano BBUN 26 bottom bracket loose using the Park Tool BBT-32 tool. I tried a14" adjustable wrench. But the splines on the bracket are very shallow and the BBT-32 kept slipping off. Then I tried putting the BBT-32 in a 32mm shallow socket on top of some washers to get the tool's splines above the top of the socket and used a1/2" ratchet, then a 1/2" x18" breaker bar. It still kept slipping off. Finally I used my Milwaukee 1/4" driver and that worked like a charm. It beat on it for a couple of seconds and then spun it right off. i don't know if this is an approved method but it does allow you to keep pressing the BBT-32 into the splines and not allowing it to slip off.
And thanks for vids... very helpful
Sir thank you I learn more to you
Have a strange noise in my brand new Riff BB, probably gravel, now I know how to take it out and clean it.
I'm tearing down an old hybrid bike of mine and made the mistake of just looking at one of the sides before ordering the tool I needed. The non-drive side bracket has three notches and the drive-side has two flats. I was shocked to see this after I got the non-drive side off first. Luckily, I had just bought a wrench that just barely fit onto those two flats. But, I'm not sure if I did something wrong again because a bunch of bearings came pouring out when I removed the drive side bracket...
4:54 "But if you have nothing else, at least use some grease..." - would somebody please tell bicycle manufacturers about this!

Nice video, I've got a 7 year old Apollo Feud Mountain bike the bearings in the crankcase have worn out making the pedals wobbly so I need to replace the bearings where the pedal cranks go, But I don't know What Type of bearings set up would I need for it? Might it be a new bottom end bracket cartridge type or one of the other types of ball bearings crankcase/bottom end bracket types, and what tools would I need to get the job done.
HI I doing a couplet bike build. So how do I know if I need spacers on the BB?
thanks bro.

Park tool I have a square taper bottom bracket. Question is is it possible to get a 1 inch longer bb axle. So I can fit a mid drive motor between my crank arms. I need it wider to be able to pedal when battery dies?
Thanks
I luv dis guy
Would it be better to get the outside sealed ones I feel like dirt will clog the outside threads
quality education
i got a new bottom bracket for my fixed gear.(Integrated crankset Single speed) but reallized that it had shortened the botton bracket length after install;;
I came here to make sure the way to turn the bottom bracket and of course I got one bike which got an opposite threads on BB. I broke in the frame... but it is sorted I just didn't expected
Is Copper Grease suitable for this application?
Bought a walmart bike.....just trying to tighten the bottom up. It has knocking sounds and some wiggle to it. I doubt the bearings are shot. Its brand new. I did get to buy some new tools. Thats always fun.
the hardest part is knowing what you have and then getting the right tools.
Do you lubricate the crank when reassembling?
Hey Park Tool, how do i find out if a have a Shimano octalink V1 or V2? Trek Road bike.
At 3.28m you say turn counterclockwise for Italian threadings. My Specialized Rockhopper has no indication numbering on ring and drive side is REVERSE threaded, which I understand is more common. Tried normal for a while until figured CAN"T BE! then reversed it off. The curse of Proprietary parts. No damage done All good in the end.

Check also his video for stuck bb 😉. Really helpful !!!
okay, just wanted to make sure I was turning the right way to remove my external threaded bottom bracket. I was, the thing is just on there really tight, even though I used anti-seize. Gonna have to bust out the rubber mallet I guess.
I have a VP cartridge style BB. Can you repair them? 10,000 miles on mine.
Calvin Jones just got cooler.. (the background music tho)

The BB shell on my bicycle measures 77mm, tho I didn't use a caliper for the measurement but it's definitely nowhere near 68 or 73. How/where do I get one that fits.
Hey, excellent content as always but I have a question. Shimano’s notice says don’t use grease on the tread when the cup is made of plastic, do you recommend that and most importantly why ? Thanks !
@AnotherMrLizard

Grease is to form a barrier between dissimilar metals such as aluminium and steel but if your bb is plastic then there’s no reaction going on so it isn’t needed.

I have an old bike that i wanted to renew, but when disassembling it i noticed the brackets on the drive side of the shell go counter-clockwise to remove (and clockwise to tighten) so conventional parts as cartridge bottom bracket (i had bought one with integrated spindle) do not fit, do you guys happen to know if there are available some integrated cartridges that are compatible with my bike? (The model is a Rabasa Panther Mach II, is a bikecross/bmx like bicycle from 80-90s)
