How to prevent BB tool from slipping

[weisan]

Trying to remove my bottom bracket using this tool, but it keeps slipping off its tracks...any special trick?

piece of all thread, some nuts, washers, and a wood block or two. big wrench, since you won't have access to the socket receiver.

And I know you know this, but make sure you know what kind of threads your BB has so you're going the right direction. Don't ask me why I emphasize this.

Depends on if the spindle is still going through the cups. If the spindle is still there use a long bolt through the tool and into the spindle while breaking the cup loose.

If there is no spindle in the way feed a long bolt through the tool and BB and use washers on each end and just snug down the nut on the bolt. Break it loose and then remove the bolt.

Make sense?

In a pinch I've laid the bike on the floor so I can put pressure downward to keep from slipping off while turning it. In desperation I've used a large wood clamp to keep it fixed then a nice solid tap from a rubber mallet to free it up.

Oops...left out one important detail....but first off, thanks to my pals coming to my rescue immediately, I won't forget you....

The picture I posted is not exactly the one I have.
I forgot to mention that the cheapo BB tool that I have does not come with the taper sides. It's rounded all around...so I couldn't bolt it down and then use a wrench.

I've done this but instead used a rear quick release skewer and some washers. Works great.

Do you have a workbench vice that could hold down the socket wrench?
I usually put my BB tool in my vice for the stuck ones and turn my frame. Just gotta know the right direction to turn.

Above on the right side of the photo is the tool I use, from J.A. Stein.
Holds most of the smaller splined tools, screws into the bottom bracket spindle, and gives you much leverage.

It's a two-way tool that I use for both removal and installation.
Not cheap -- I see it's $110 (http://www.biketoolsetc.com/index.cgi?id=70586927695&d=single&c=Tools&sc=Bottom-Bracket&tc=Cartridge-BB-Tools&item_id=SN-CBBH) -- but if you do that kind of bottom bracket work enough, really makes it so much easier.

Dave, who loves a good bicycle-tool thread like the other one going about JIS screwdrivers

if you don't have wrench flats you can use a pipe wrench after clamping it together.

Bing Bing Bing we have a winner!!!

Take a carriage bolt with the head a little bigger than the inner diameter of the tool.
Put it in a drill press and reduce the head with an old file at at high speed so it is SLIGHTLY bigger than the inner diameter of the tool.
Cut off the thread right below the square part of the bolt.
Drill a hole through the center of the bolt head and cut a M5 thread.
Press the gizmo inside the tool (press fit like) and you're good to go.
Now you can use a QR skewer and some nuts and washers as spacers to clamp the tool to the BB cup.

You can still use the it with a 19mm wrench/nut or with a 1/2" ratchet since the bolt head won't interfere.

Works like a charm...

I used a cheap Icetoolz one for ST BBs and Campagnolo cassette lockrings but the same concept should work for the tool you are using.
Might require some modifications, i.e. different bolt with a bigger head etc.

I use something similar to what Mr Sinill is picturing.

I want to express my appreciation to the pals who have shared their grandmother secret recipe..er...I mean, Shaolin Temple BB removal Buddha Palm Technique...those who inserted pictures, even more impressive, Black Belt Grandmaster 8th Degree.

I hope this serves as a resource for others who encountered the same problem.

For me...after like 4 hours of foreplay, and not having the right tool, I finally gave up and just went ahead to ship the bike out with the BB cup intact. Fortunately for me, my superstar painter was kind enough to suggest that I leave it as is and he will remove it on his end when he gets it. Whew...! ;)

Honestly, I still don't know what this is....sorry...it's Friday, hit my quota...time to vegetate for the rest of the weekend.

That screws into the spindle (tapered one side/octalink or isis the other). You thread the large washer part down against the BB tool which goes onto the BB splines, & you can put a socket on it and the tool won't slip. It's basically a fancy bolt to hold the tool in place.

for outboard Hollowtech-type bearings. Yea!

I remember using a quick release in a situation like this before. Kinda like this...

This! Plus a 24mm deep socket (for my bb tool) and a 1/2" breaker bar has always worked for me.

Put the bb tool in place. Thread the above tool into the bb spindle and snug up the threaded knurled bit against the bb tool holding it in place. After you break it free don't forget to unthread the knurled bit or else you'll just stretch and eventually break the tool

I've got a pivoting head ratchet here in the shop that works wonders. Get a little inward pressure and keep the handle slightly pointed in towards the bike and things don't slip.

I have to get some *seriously* stubborn BBs out, so I'll add a 3' pipe to the end of that ratchet and use leverage to my advantage.

Just remember which direction you need to turn the BB cup to get it off. AMHIK

Did this once in a shop I worked in the late 90s. It had soaked for days with penetrating oil, impact wrench failed, heat had no effect, 2 foot breaker bar failed. Laid the frame on the floor to push against it with feet while pulling the cheater pipe... BIG cracking pop and it was out. It was a French threaded BB, that I remember. It turned out the customer was amused with how he abused the 20 year old 27" wheel bike so after we finished converting it to 700c and updating the parts he bought a new Merlin.

These with great, they're cheap, and easy to find.
