They simply unscrew.
Are you trying to remove the front or the back ones ?
The front you need to lower the suspension to the bottom.
The back ones you need to start the unscrew movement with the suspension at highest setting. For this you will need a chain wrench, when it starts to move, lower the suspension to bottom and unscrew.
WARNING. NEVER WORK UNDER THE CAR UNLESS IT IS SUPPORTED ON STANDS OF SOME KIND. THE SUSPENSION CAN DROP QUICKLY WITHOUT WARNING.

Dont forget to de pressurise the system by unscrewing the 13mm(?) screw that is on the Pressure regualtor (beside the front green bomb). Only need to twist the screw 1/4 turn until you hear the hiss of air running out the system.
IF YOU DO NOT!!!!
Then it is A, Harder to undo them green bombs and B, They will explode like a Bomb.

Never changed the rears, but with the fronts i've never touched the pressure release screw, i just pop it on low & then they've been fine to get off. I do normally leave it a few mins before unscrewing them & only get a bit of lhm spillage.

The pressure release screw has a 12mm head.

Back on two wheels and pedal power for the moment.

The advice have always been given in over 20 years of BX ownership is ALWAYS release the pressure when dealing with high pressure componants. Applies to anything thats pressurised.
How many front spheres have you replaced mulley?

I've changed the fronts a few times on more than one car, never had a problem as surely when the car has been put on its lowest setting its effectively de-pressurised enough to enable removal of the spheres. I understand that there is some residual pressure still in the system, but presumed that this was low enough not to cause any issue. Must admit i've never changed the rears, so would have asked for advice regarding the safe removal of them.

The only sphere you *must* depressurise the system to remove is the accumulater sphere.
As said above, the front's can be done by just dropping the car to low.
The rears will be almost impossible to remove if you depressurise the system since to get them started you put the car on high to lock the cylinder in the subframe, if you don't then the chances are the HP pipes to the cylinders will break.
Once the rears are cracked off (ie undone about 1/4 turn) then drop the car to low and undo by hand.

Smokes lots, because enough's enough already!
Far too many BX's, a bus, an ambulance a few trucks, not enough time and never enough cash...

I agree, I've never released this screw to change front or rear suspension spheres as putting the car in low releases the pressure. The screw is only necessary when changing the accumulator sphere as that pressure will still be held when the car goes to low otherwise. This must be what Kiwi is getting confused with.ken newbold wrote:I think you'll find that if you undo the PR screw with the car sat at normal height, it will stay where it is.
Likewise if you have a flat sphere that is holding a back pressure, undoing the PR screw doesn't help there either. You either have to wait for hours or just get LHM everywhere

I guess that if you're worried about any pressure remaining in the system, then there's no harm in releasing the pressure via the screw, just means extra hassle having to re-pressurise, each to their own i guess.
I had heard that was the way to do the rears Doc, i'm sure sooner rather than later i'll be changing some.

my personal prefrance is to do it as i dont want to have a LHM shower again and am happy to wait till the presure builds up as it doesnt take to long
whats an extra 2 to 3 minutes to sit and reflect on a job well done
I look at it like this
If your over cautious and take some extra measures that may or may not be worthwhile. You cant say you were not advised!
Bit like telling someone saying you can jump off a cliff and survive. Someone will say they have and you dont need to worry about death! Such is the intenet advice thats given.
Better safe than sorry if it works for you then thats fine as well.
