[@jackglossop4859]

@@becyk_du_quebec I remember when GCN did a ‘fix squeaky seatpost’ video and the seat post they used to demonstrate it was some teardrop carbon fibre aero thing. Ridiculous.

[@tenpennyguy]

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.

[@tristanwwsd]

@enriqueamaya3883 I talk to Jesus every time I deal with out of round BB's.

[@ClaudiuB]

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

[@namdarbolour9890]

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.

[@rich8037]

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.

[@stateofdecay2210]

I can’t thank you guys enough for making these videos. I’ve been able to do most bike wrenching myself thanks to you guys! Easily some of the best instructional videos out there

[@centraterasen]

Calvin, you are the man and the instructions that you provide on this any many other topics are pure gold. There are a lot of hacks out there but you are the true diamond. Thank you for sharing of your experience with the masses.

[@erikwiseman1702]

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.

[@claudiustanculescu6743]

I think a hint for the competitor tool would help a lot of people, so many got this problem.

[@carnub]

Fantastic guide. So clearly presented and love the advice for those without a torque wrench and unusual greases!

[@jeffdavis291]

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.

[@codyhughes5520]

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.

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

[@CoryRamirez000]

Got around to doing this today, never removed a bottom bracket before. BB would not come off until I sprayed some WD40 penetrant; came off like nothing after that. If the cranks and whatnot don't fly off after like a month, then I'm guessing I got the torque stuff right. This video surely helped, and easy to follow directions.

[@pbjbagel]

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...

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.

Thanks Calvin! Trying to see if I can upgrade my old cartridge BB with a hollow-tech version of lighter weight.

[@mrenormouscroc]

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.

[@parktool]

A Rockhopper will have a BSA bottom bracket which is reverse threaded on the drive side.

[@topspin6418]

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.

[@RockoDSS]

Thank you!

[@Pogi27]

Sir thank you I learn more to you

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

Only the Italians would make a crazy bottom bracket thread.

[@noahfontaine7832]

actually, the British thread is reverse threaded...

[@thepaincave8272]

The French do the same :( ... Having a cup and cone BB unthread itself on the road and scatter the ball bearings all over the place is a great experience ... Note to self DON'T forget the thread lock!!!

[@saiket1735]

I am learn how to upgrade my bike, one thing I notice that is so confusing and hard to remember is that all youtubers keep saying to turn clock wise, counter clock wise, left side, right side....etc. well, let me use the KISS formula (Keep It Simple Stupid) and make it easy for everyone to remember. Regardless of which side that you're working on, left or right, remember this: Pull Back and Let Go. to tighten the bottom bracket, turn your wrench toward to the Rear Wheel. to loosen, turn your wrench toward the Front Wheel. I'm done here.

[@parktool]

You can pull towards the rear wheel in a clockwise or counter clockwise rotation depending on the wrenches orientation. The clock only spins in one direction.
