Sphere Removal Tool- Co Durham

Post by McNasty »

Just spent 2 hours[:(!] breaking 2 chain wrenches and a strap wrench trying to remove the accumulator sphere on my Xantia 1.9 TD SX[:(]. I've got the new sphere and want to fit it as my "tick interval" is short and when i turn the wheel the pump seems to work overtime.. The big question is..Has any one near to Darlington got a sphere removal tool ( and a ramp- just kidding) that I can borrow[?]

You could always try a sphere removal tool like mine (see picture in post above).... nothing more than a clip to hold pipes onto the ceilings. At least, you've got plenty of space around the accumulator to use it (i think... never saw the engine compartment of a Xantia TD).

For an accumulator sphere (on BXs) I have succesfully improvised with the "large jubilee clip, cycle inner tube & hammer " method detailed on the BX DIY site. Suitable-sized clips are available in B&Q - or at least they were when I did this. They were sold as accessories for air-ducting used for tumbledryers and extractor fans.

I've always used a decent, sharp chisel. The old sphere is dead anyway. Then screw the replacement on only hand tight.

Thanks for all the advice guys. I called a man who was advertising in the local paper as a recharging specialist. and he gave me the hammer and chisel solution. I jacked it up put it on axle stands and chiseled to success. The tick time on the regulator is normal but the pump still seems to work hard when the steering is operated. Im happier though; cheers for the replies.

Just a quick one, which MAY be related...
The tick interval on my BX isn't perfect. but it's not bad. When using the power steering (at standstill - naughty boy), it seemed to be a bit "heavy", but OK when revving the engine a bit. Noticed by looking at the pump when the reg cut in that it actually slowed down, even though the engine didn't...Might be worth checking your belt. Mine doesn't squeak, just slips...Time to adjust it, me thinks!

Hello McNasty
I broke 2 chain wrenches and a heavy duty commercial vehicle strap wrench trying to get the accumulator off my XM. Took it to a Citroen specialist (only time I admitted defeat and paid a garage to work on my car) where after the job was done I asked the technician how they did it. "We used a hammer and chisel"
I know Citroen use a special tool to remove spheres but I'm not sure what they look like.
Just glad it wasn't my head under the bonnet when they shifted it!!

I read in 'Car Mechanics' magazine some years ago that on no account should the hammer and chisel method be used to remove a sphere - even 'dead ones' The article, (concerning a 2.1 XM) stated that even a flat sphere could be retaining pressure that could cause the sphere to rupture with potentially nasty results for anyone working on it. Has anyone out there actually seen this happen or know of any incident where a hammer and chisel was used to loosen a sphere?

Try this on a C5 spheres and with luck, you can hit the programmed rupture point on the sphere (just so the sphere won't blow into smillerines[?] with excessive pressure - a "safety" add-on).

I cut up a good sphere a few weeks ago at work, to see what they looked like, I used a large industrial bandsaw and hid behind a guard expecting a loud pop, but thats not what happens, in this circumstance just loud hissing for a couple of seconds.
Bit dissapointed really[:D]

If there's any doubt about retained pressure in a sphere, just screw the small cap off the end usin stilsons or multi grips; that's where they charge them from.
You don't have to take it fully out unless you want to, just slacken it off as it sits on an "O" ring and after about 2 turns if nothing's come out, it isn't going to.
Probably a good safety tip as these things can have 45 bar in them when fully charged & I've seen apparently "flat" ones still holding say 50 - 100 psi that will realy go off with a bang when the charging nipple is removed.
Going on the thickness of the metal, I feel the only thing it would do is assist in rather fast bodily functions with the noise it might make as the nitro escapes, rather than go off like a balloon and blow your head off.

I have followed this topic a number of times and always wonder why you dont just invest in a purpose made tool ?
They are readily available, cheap and durable enough to last a lifetime (for home maintenance use).
The hassle avoided, danger avoided and time saved on the first use gives a total ROI, in my opinion.
While innovative solutions are definately a requirement for DIY Cit maintenance they should only be applied in the absence of reasonable cost off the shelf solutions.

Since the issue here is DIY - why not make yourself a tool that never lets you down, would cost you nothing if you're the type of home DIY'er that stock about every bit usable at a later time. The tool is so simple to make in an hour or 2, if you suddenly realise you need one here and now :

How do I get hold of the official sphere removal tool? I have tried the usual tool suppliers and Halfords staff just looked at me with a 'What's a hydropneumatic sphere' expression on their faces. (knew that would happen- I just wanted a laugh)

Pleiades sell them (google for it) but why not just do as Anders suggests and make one?
I made one from scrap like the Pleiades design; took about half an hour, and it never fails to remove a sphere. I would never use a hammer and chisel
