Anyone?

I don't have one, but there are other ways of removing a cup and cone BB. Which bit of it do you still have to get out of the frame?
-
• #4
I have the main section of bottom bracket out, just this side to get out.

I have tried mole grips, spanners, locking tools and no luck so far.

it might well be seized, (I assume you are undoing it, it is reverse threaded to the other side, i.e. it is a left hand thread)
A large adjustable spanner will work if it isn't seized, if it is seized it will be a bitch without the tools!
I don't think even the Park tool will do it if it is seized, that lug on the BB shell doesn't offer much purchase. A trip to you local bike shop might be on the cards. -

actually, thinking about it
a) is that definitely the r/h side (i.e. the picture is the right way round isn't it!)
(because that looks like and adjustable (l/h) cup
and
b) what frame is it? it isn't an italian or french threaded bb is it? -

Looks like the fixed cup on an old Raleigh. You didn't by any chance used to have cottered cranks? Mark Stonich at Bike Smith Designs has a natty tool for just that application. It is a bugger. You can also use a hammer and an old flat head screwdriver if you can work out which of the flats to apply the persuasion to to make it turn the correct way. Or if you have access to a heavy duty bench vise, with some careful balancing, you can grip the flats and use the frame for leverage. A suitable soaking with WD40 will also help.

That's the right side. Forks are to the right of picture. The frame is an ammaco Monte Carlo frame. Not sure on what thread it is. It's a shame as I just can't get a good grip on it with a large adjustable spanner. It wants to just keep slipping off or rounding so need the tool really.

The bottom bracket was a square taper, but the type with the thread attached to the end so the crank would have to be bolted on, if you know what I mean.
Got the frame for free the other day so am trying to build it up as a runabout for a while. -

Got the frame for free the other day so am trying to build it up as a runabout for a while.That's very similar to an older Raleigh then. I would try the WD40 then hammer and screwdriver method. Best bet being it unscrews Clockwise (opposite to the left cup). Don't worry about damaging the cup, it should go in the bin anyway. Replace it with a £18 Shimano cartridge unit.

I have a nice shimano cartridge unit ready to go on so should be all good once this bugger is off.
It's really frustrating, would love to try the hammer method now but with the kids asleep it's best to keep quiet or all hell will break loose! -

Grand. I've had to take apart many shit heaps in the past due to mine and my friends' unwillingness to buy new easy to work with bikes. There's usually always a way. Often involving swear words and hubris but the job get's done, eventually.
Case in point, making the below fucker last for 150 miles every year on our annual Rugby Club bike ride.

• #13
Ha, fantastic, bet that's great fun!
Yeah swear words are always on the tip of my tongue, and fingers and hands are nice and sore from slipping spanners!

angle grind the edges for more purchase, if still no luck, maybe make a small hole in in (with angle grinder again) so you can stick something in it and you can hit it properly, all else fails, weld a bolt onto it, stick bolt in vice and turn, also blow torch might help. having a friend help you can help a lot, i.e. two people, 2 spanners

Thanks for the help guys.
Will give it a good go tomorrow and maybe take it to work with me to gain access to some power tools. -

Have a read of Sheldon

see his nut / bolt / washer method -
• #17
Ummm. That could well work. Might give it a go now if I have the right bits.
Cheers. -
• #18
It's quite tricky (read: never worked for me or anyone else I know who's tried it). It's difficult to torque the whole assembly enough to grip the cup enough if it's properly stuck.
-
• #19
It only ever worked for me once. Worth go though.
-
• #20
Need to find a bolt and some washers at work tomorrow then will give it a blast. Cheaper than the tool anyways.
-
• #21
Tried it, no good! Going to have to swallow it and buy the tool.

I had the same problem once and that tool did not do the job as it was slipping of the edges of the cup, and it's short so you will not have much leverage to unscrew a seized cup. Even though I've put loads of penetrating oil and blowtorched through the BB shell to see if the cup expanded.
I did cut a slot across the cup (not all the way, like a screw head) with a Dremel (quicker with a bigger tool) and I've tapped in the flat end of a mini pry which is about £3 from an ironmonger. Like this one
https://www.tomboytools.com/shop/HAND-TOOLS/!Mini-Pry-Bar
Put the other end on a vice and used the frame (on its side now) as leverage making I've rotate it the right way (clockwise or anticlockwise depending on the BB thread you've got).
Mine gave in the end. -

Hopefully it isn't seized, I just can't get a good grip with any spanners. I have ordered the park tool now so hopefully that will sort it, if not then will have to take it to work and try the hammer and chisel technique!
Hi all, I'm trying to get the remainder of the old bottom bracket off my current build and am in need of the park hcw-11 tool.
I have tried numerous attempts to get it off but am struggling somewhat!
Does anyone have one I can pick up tomorrow or send me?
Cheers, jack
