Removing a Very STUCK Bottom Bracket (Square Taper)

Тәжірибелік нұсқаулар және стиль

Bottom brackets can be seized or stubborn over time, especially when water gets into the frame or rusting in bottom bracket area.
Remove both the crank arms with the crank puller.
The square taper bottom bracket contains the cup and unit and taking the cup out first is preferable.
1994 Trek 930 SHX Singletrack - Shimano BB-LP30 / 73mm / 118mm Axle
1996 Specialized Ground Control - Shimano BB-LP26 / 73mm / 107mm Axle
The plastic or metal cups can be on either sides, so keep that in mind and identify your bottom bracket first. Like the Trek 930, the cup is on the drive side. On the other hand, the Specialized Ground Control has its cup on the non-drive side.
Turn it counter clockwise to remove.
The cup is removed, but not the unit on the other side.
Heating up the bottom bracket could help to break it loose.
Bring out a headset cap and crank arm fixing bolt.
Insert the bottom bracket tool, headset cap and crank arm fixing bolt to secure the tool in place.
The headset cap is from a quill stem converter.
If the crank bolt is too short, you’ll then need to find a M7 bolt in your local utility store but it could be hard to find.
Turn it clockwise with the wrench.
The adjustable wrench didn’t work out, so next step is to use the breaker bar with 32mm socket.
Clean the bottom bracket shell and then lubricate the threads and area.
A Hollowtech II bottom bracket will be installed.

    I want to thank you so so so much. I had been trying to use a socket wrench on the removal tool to loosen the non-drive side. No matter how hard I tried, nothing. Then I saw you use a big wrench, which allowed you to hold everything tightly in place with your free hand. I tried that, and it broke free. Blessings to you!

    This is the gift that keeps on giving. Wouldn't have occurred to me to put a bolt on there! I put a bolt on, hit it with my heat gun, and stomped on it. BOOM! Finally got it loose. Thanks for saving me a lot of frustration!

    well mine was a lot more stuck. what worked for me was flap wheeling the face of the thing until all tool fittings were gone and it was flush with the bottom bracket shell. then using a die grinder with a burr bit i carved through the race in 2 places on opposite sides. a hack saw would be great here in theory but the race is so hard, all the teeth on your hacksaw just wear down in seconds. so after turning the threaded race into 2 parts, you are able to pry it away from the threads. this leaves damage in 2 places in the bottom bracket threads but its better than throwing the bike in the garbage.

    Mostly headset caps are gonna fit with M5 screw, just get a big washer that fits your crank bolt instead of the headset cap, I removed mine firstly on the non drive side ( the cup ) to flood it with WD-40 or oil to make the drive side ( unit ) easier to unscrew, and I broken loose the drive side with the adjustable wrench with a long pipe

    @@DanyoSports Interesting. I thought the crank bolts would be universal in diameter and pitch. I think it's also worth pointing out that if both sides are tight, take the cup side off first otherwise you won't have a spindle to screw onto and make sure to loosen the bolt a little on cup side as you untighten so you have space to allow the tool to back out.

    Not all bottom bracket bolts are M7, I ordered M7 x 40mm to do what you said only to discover that the bolts on my Carrera Karkinos are M8, so I got M8 x 40mm, bottom bracket still wouldn't budge, then we clamped the adjustable spanner to a scaffolding pole with a flattened end, still wouldn't move, heated the bottom bracket up and tried again, this time two of us were pushing down on the scaffolding pry bar extension when the pressure became too much and the jaws of my heavy duty stanley adjustable snapped. I don't believe that your video is very truthful, that bottom bracket that you showed, the one that was allegedly rusted on, was definitely removed and then replaced for the making of your video, because there's not a chance in hell that a bottom bracket that was rusted on, released as easily as you portrayed in this video, no chance!
