    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.

    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.

    Yeah, I admit. I first just tried to remove the drive side - and it wouldn't come loose - just slip. Tried the non-drive side, but my confidence was lower, and it slipped, whatever way I tried. I then set the bike down on the ground, and tried a different, better fitting tool. It slipped once, so I gave up and watched this video. That did it! Did the NON-DRIVE side, normal thread, then the DRIVE SIDE (reverse thread).

  • @rich8037
    @rich8037 Рік тому +5

    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.

  • @namdarbolour9890
    @namdarbolour9890 2 роки тому +39

    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.

    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

    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.

    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.

    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.

    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...

    • @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.

    • @parktool
      @parktool  Рік тому

      You should pick one or the other. The anti seize will prevent the thread locker from doing anything and the thread locker will dilute the anti seize. If you have a bottom bracket that keeps coming loose I would recommend using thread locker. Be sure to torque the driveside and then the non drive side. And if it still continues to happen you may need to have your bottom bracket faced to ensure proper fitment.

    6:22 can you regrease both bearings on that type of bracket? I have something like that but I couldn't get to the bearing covered by that threaded plastic thing :(

      Those bottom brackets are considered non serviceable unfortunately.

    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.

    OK, I have thread locker, anti-seize, and grease. Which should I use?

      There are cases for each. If you have all 3 and no reason to use one over another I would recommend Anti seize.

    Are threaded thru BB spindle interchangeable with cartridges?? I am wondering whether I can swap my shimano cartridge BB-UN300 by a compatible threaded thru BB. Any tips for compatibility? I want to upgrade from the square taped! Thank you!! Very good video btw!!

    • @parktool
      @parktool  2 роки тому +1

      You can very much upgrade to a two piece style thru spindle crank. You will still use threaded bottom bracket cups. The cus will depend on the crank that you choose. Most cranks are compatible with threaded bottom brackets.

    Great and very usefull video! Just a simple question, what is the purpose of those spacers? I took my bike to my local shop to replace the bottom bracket ( replaced mt500 for a mt800) and just noticed that they put the 2 spacers on the right side but none on the left, when I asked they said there was no problem with that but I was still concerned about it, and even in the shimano page they indicate to place one spacer on the left, will that cause any issues?

    • @parktool
      @parktool  3 роки тому +2

      Interesting that they have it setup with 2 on the drive and none on the non drive. Typically there will be one on the drive side to account for what is called an E-Type front derailleur or bash guard. Then, (if a 68mm bottom bracket shell) they will run an additional spacer on both sides for a total of 3 if a 68mm or 1 if a 73mm shell.

      @@parktool Thanks a lot for your answer! They already corrected that because it seems the technician forgot about it and the crank spindle was moving side to side, so the other spacer corrected that problem ( my bottom bracket shell is 68mm), I purchased the Deore M6100 1x12, but the right crank arm slightly touches the chainstay the moment I apply pressure on the left pedal and more when going uphill, does that mean I need a different crankset? Any advise in regards to that? I ride a hardtail by the way.

    Do some thread cups not use the internal spacer?

      Correct, but those are actually sleeves. Some do not use any sleeve between cups.

    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)

    I have a question (GREAT vid by the way!). I am doing the TruVativ conversion kit to go from ABB to BSA. The TruVativ cups and my euro BB are both aluminum. I would lean toward thread locker (options 1 and 2 in your vid) but in a GCN vid on lubes Simon mentions aluminum bolts are prone to seizing. So if the TruVativ adapter and my BB are aluminum should I use ASC-1 instead of thread locker? Same question for snazzy aluminum chainring bolts I bought (where I would have used threadlocker)...PPL-1, threadlocker, or ASC-1 for those as well?

    • @parktool
      @parktool  4 роки тому +1

      Kinda depends. The RC compound/ thread locker is going to give seperation between the bottom bracket material and the frame material. So will the ASC-1. If the fit is a nice pressfit then i would go ASC-1 but if the interface is loose i would suggest going to RC-1. Check out this video. ua-cam.com/video/W9zPkrCtWEM/v-deo.html&t
