    I am working on my freinds 86 Fazer with no manual...
    I am replacing the fork seals but i cannot see how the tubes are being
    kept together.

    I have removed the piston and everything above it and the bottom screw


    Whats left on (Per the parts breakdown list)


    METAL, SIDE
    GUIDE, COVER UPPER
    OIL SEAL, SWOTYPE
    CLIP, OIL SEAL
    SEAL, DUST
    SPINDLE, TAPER


    Is there something i cant see in the tube holding it together?


    Thanks

    I don't know about your bike in particular, but usually there's a
    circlip underneath the dust seal (and if your parts list is in order of
    installation, then it's there) that has to be removed before you can
    disassemble the tubes.

    Maybe these sites will help:

    Google found them for me with "fork tube disassembly"

    I strongly recommend obtaining the manual for bikes that you own, and
    you might want to tell you friend to do that. It's _much_ easier with
    the manual.

    Please note - what I say now may cause damage to components
    that can be expensive or hard to come by.

    If the forks you work on are like some Yamaha (actually Kayaba)
    forks I have worked on, John Johnson is exactly right. What
    you need to do is get at and remove the oil seal circlip. What
    might not be obvious is what you do after that.
    You pull the stanchion out of the lower leg. This requires speed
    and force but then both the bushing and the oil seal will be
    pulled out by the lower bushing that sits at the bottom of the
    stanchion.
    My warning above comes from experience with a Suzuki where
    this did not work. I can't remember exactly how but it was
    different in some way. This is where the manual can save you
    money and frustration.

    Another little thing you might not think about but that is very
    important is to bottom the fork before tightening the piston
    rod screw (the one at the bottom). This is needed to align the
    tapered hydraulic stop with the bottom of the stanchion. If
    it is slightly off centre, you get metallic contact rather than
    hydraulic lock if the forks bottom out.

    I was thinking the clip under the dust seal was holding things together
    but wanted to get confirmation before risking damaging the dust seal.
    Thank you both for the tips, off to the garage now to work on some beer
    (and maybe a fork or 2)
    PS, I have manuals for my bikes, 99 Triumph Sprint, 86 Honda Night Hawk
    & 87 Husqvarna 510. My friend has been advised :)
