Removing old BB cups

I'm having difficulty removing the BB cups from my ancient swinnerton beater. I don't have the correct tool and have tried searching for it online, no luck. I imagine the tool would be similar to a cone spanner as the cups have a raised rectangular section through the middle. Anybody know of the tool needed?!! Cheers!

Hammer and chisel.

If as I imagine its the old school cups with two flats on them they can be hard to get out even with the right spanner.There is a workshop tool that some shops will have that goes through from the adjustable cup side (assuming this has been removed)with a piece that tightens against the fixed cup from the outside as this is tightened it will undo the cup which is threaded the opposite way

Does that make sense?

Get a bolt that just fits through the BB cup and tighten a nut on to it in the direction of undoing the cup so that you can tighten on the bolt until it grips the cup and undoes it.

A little gentle heat with a decorators heat gun around the frame BB helps too.

From your description Its sounds like a fixed cup remover, (but there again what the hell do I know)

You will need to remove the adjustable cup and lockring before this can be utilised

Hacked2 I know what it is but its not the most common tool around so I thought I would try and explain it to a guy with a problem

So the picture link should be helpful then
the bolt and nut idea sounds promising

sounds like a cheaper option!!

reckon you need a hcw-11

Park stopped making them for a while but now do again :)

mine had rusted themselves into the frame and had to be sawed off

Those Park type tools are crap on seized cups the flats just aren't wide enough to get any purchase the bolt through the bottom bracket sort are much better and you dont shag the paint up either.

I've never seen a bolt through BB remover that fits the flats on an adjustable cup that I think is being described here, any links to one?

Sheldon Brown's DIY fixed cup removal tool instructions are worth a look though I've never actually made it work...

The problem is usually removing the fixed cup the Park tool fits one with large flats machined onto it.The even harder to remove fixed cup has a very small flat edge that is barely lower than the bottom bracket shell.Th spanner slips off these easily if the cup is tight and hard to move.The adjustable cup is usually easier to move with a spanner with two pegs on to fit in the hole on the shell of the cup.I have used a bolt through remover to shift the cups on a 20 year old mtb bottom bracket and even then needed extra leverage but they do work

So, to summarise. The park hcw-11 is a perfectly good tool to deal with the adjustable cup described in the original question?

And to remove the (often more troublesome) fixed cup you can use either a "bolt through" remover (link to follow edric64?) or you can make your own DIY remover Sheldon Brown stylee or you could try the park hcw 4 if the fixed cup needs a 36mm box end spanner.

p.s. some park tools are crap, some are serviceable, some are great. I love the hcw-11. Don't know what the weird pins at the other end are for though. Anyone?

Is it this type? If it is then I wouldn't bother buying a new tool, why not use a vice and turn the frame?

A vice would work equally well if it's one like this:

the first pic is the type of cup i'm having trouble with. Unfortunately I don't have access to a vice. I don't suppose anybody has the tool?

Bugger. Sure someone's bound to have that tool though. Good luck

The pins are for adjusting the adjustable cup as shown in the post above where the cup has holes in A vice will not always grip those flats very well as they do not protrude much and its easy to shag paint or hit lumps out of the bottom bracket shell if the cup slips in the vice

Hacked2 has the link above for the tool I think I am on abouthttp://www.wiggle.co.uk/p/cycle/7/Cyclus_Workshop_Fixed_Cup_Tool/5360041218/

don't forget it's a reverse thread to unscrew plus that raised section is normally 16mm so an open ended spanner bolted tight with a large washer should do the trick

Don't think so, these wouldn't fit in an adjustable cup that needs a pin spanner to work with.

See:

The Park site usefully says: "The opposite end has two ears that are 23mm wide and approximately 5mm wide." No info on what it's for tho.

Anyone?
