    Default New BX Spheres

    Hi All

    I thought I might give my BX a christmas present.

    Now that Mel is gone, any ideas where I can get spheres for a bx in melb or outside of melb with not ridiculous postage?

    Thanks
    G

    I got some from EAI, but I think they only had the fronts for my 16V so YMMV.

    If your a member of the CCCV you can get the spheres regassed for a modest fee.

    If you must have new ... try the usuals. ie: Dave Cavanagh, AEI... etc... The melbourne based guys. You can collect that way and not pay postage.

    It sounds like a lot of places are out of stock. If you can't find stock locally, next step is ebay uk ( support the local guys if you can though, if no-one buys from them, they'll dissappear and we'll have no-one then).

    G,

    If you want to give it a long lasting present, get some Xantia SX front spheres for the front and a Xantia front centre hydractive sphere for the accumulator. The original spheres from Citroen are double membrane spheres and they don't lose any pressure for 10 -20 years so don't need regassing every 2-3 years.

    My BX TZi loved this combo until the lack of ABS, poor driving attentiveness and the back of a Hilux brought it to a premature end.

    Cheers,

    Ken W

    Hi Ken

    Thanks for that info. Mum has been searching for that for years. Full spheres were down to bottom third of the range, and it had been exactly 2 yrs since last TLC, so go me.

    By the way for those wondering what had happened to Hekas, he is still in the same old spot.

    Ken, bugger about that Hilux!

    How does the valving in the Xantia spheres compare to the BX valving though? I have a BX estate with "standard" BX spheres and these a very different to the BX16v spheres on the BX16v. This is not solely due to the different pressures.

    Although I can't find the table I usually refer to, this will give you an idea:

    400/55/1.8 = sphere volume/pressure in bar/damper orifice size

    The volume of the spheres has a significant effect - the 500cc spheres give a very plush ride compared to the 400cc ones.

    The higher the pressure the softer the springing.

    The orifice size indicates the low speed damping effect (a smaller orifice gives a stiffer ride), but no information is given about the shims comprising the high speed damping effect.
