    I’ve been rebuilding the forks to my xj900 and it seems there is a dispute between manuals regarding the correct orientation of the damper spindle. The first pic is from the factory manual I found off of www.xjcd.org. The second pic is from a gentleman in Canada but I’m not sure of the manual he is using. He has a video on YouTube showing how to put these forks back together with the damper spindle going on differently then the factory manual. I contacted him and he sent me the pic. What do you guys think?

    I guess the real question is why is the spindle shaped the way it is? The three washers actually fit perfectly inside the lip of the spindle but if it doesn't go that way then what's that lip for? Also, the arrangement of the washers are also different on each of the manuals. Which is correct?

    Update: After looking at the factory manual more both of the above pictures are included in the factory manual so the manual is contradicting itself.

    That's because it's just a copy of the factory manual...........and Haynes has this curious habit of renaming (and renumbering) the items in their manuals from how they are named and numbered in the factory manuals...

    Also, and I'm going by memory here, but I don't think the taper spindle has a "lip" on it on the XJ900 models........

    Definitely agree with him.
    I had the exact same issue and installing as per the service manual picture was incorrect.

    Xj900 service manual.

    Pull
    Which picture are you referring to as incorrect? The exploded diagram or the photo?

    Since I’m getting a lot of conflicting information from other forums and such I went ahead and took pictures of the two examples show in the factory service manual using my stuff. The top example is how it is shown in the exploded diagram where the washers are arranged wave,flat,wave and the “brim” or “lip” of the spindle is orientated downwards toward the wheel.
    The second example follows the PHOTO that also appears in the factory service manual and the washers are arranged flat, wave, wave and the spindle is now turned around so that the lip is facing upwards towards the handlebars. Which way is correct?

    Crap.
    I see what you mean.
    I had the exact same issue and eventually worked it out, years ago.
    Now looking at the damn service manual I can't rightly remember which one was wrong.
    Yes... I suck. Sorry.

    Inner Fork Tube Oil Lock Valve Parts:

    HCP19355 Aftermarket inner fork tube oil lock valve SPRING WASHER, fits either side. Used on all XJ750RL, XJ750P (37H model), and XJ900RK and RL models. Use 2 per tube.

    HCP19356 Aftermarket inner fork tube oil lock valve FLAT WASHER, fits either side. Used on all XJ750RL, XJ750P (37H model), and XJ900RK and RL models. Use 1 per tube.

    NOTE: the order of installation for the above washers is as follows (and only applies to bikes with anti-dive front fork systems, i.e. the XJ750RL, XJ750P (37H model), and XJ900RK and RL models):

    - after the damper rod is dropped thru the bottom of the inner fork tube,
    - a wave washer HCP19355 goes onto the damper rod shaft first
    - followed by the flat washer HCP19356
    - and then the other wave washer HCP19355
    - and finally the HCP3085 taper spindle goes on last.

    Thanks Chacal but this doesn't tell the orientation of the taper spindle itself. If you look at the two pics that I originally included from the factory manual regarding the spindle they're both different. THAT's what I'm trying to figure out.

    I would guess the taper goes down and fits snugly into the outer leg.
    Does it even fit into the outer leg the other way around?
