    Yah, I'm stumped. After reading your thread I went out and loosened the lower triples just to make sure I had done mine correctly since it went so easily. I just replaced my top clamp with the scotts damper arrangement, but it really was:

    tighten 27 to good n snug
    check drag with front wheel off ground
    loosen 27 minimally just to make sure its not too tight
    check by pulling fork legs fore-aft, make sure theres no play (there wasn't)
    recheck drag.
    Snug up pinch bolt and triple bolts, done.

    I had no change after loosening and re-torquing the lower triple bolts, and I'm having trouble visualizing what's happening with yours.

    The only thing that makes any sens to me is that you have bushing play in your newly-rebuilt fork legs, but if you're not pulling on the lowers to get the click then that can't be it.

    Stumped.

    The click is (was) independent of the forks.. I totally removed them and grabbed the bottom triple and could cause the click.

    That said.. I think I found my culprit....

    The margin between too loose and clicking and "tight enough" (from a bearing point of view) was causing it to be too tight from a steering point of view. That big rubber o-ring at the top was binding up and causing the rotation to be stiff before the bearings were actually tight.

    The lower oring shown in this photo:

    I removed the big rubber o-ring and then I was able to finely adjust the tension on the bearing stack and remove the bearing play BEFORE the steering became too stiff.

    I need to find some sort of replacement as I'm sure my bearings are now more susceptible to rain/water/rust... but in the meanwhile I was able to get the tension correct.


    I appreciate all the input/feedback everyone :freaky

    I think that big rubber ring #7 goes under the upper sealing cap #6...the other one pictured #10 is the lower seal.
    Is that how they were installed?

    Yes that's the way they were installed.. 7 was the issue.. not sure why it wasn't fitting right/well.

    I might order a fresh one.

    Question if anyone knows:

    Do you put #7 on the steering head and slide it down... or do you put it inside #6 and then mount 6?

    I installed mine over the head and had no problems.
    Looks like it should work either way...:lol3

    I'm sure Jokers right, just put the seal in the groove over the steering head and all should be fine:D. Can't see how it could offer too much resistance with retainer No. 6 pushing down on it (it's only thin sheet metal). Also you need that gap between the top triple clamp because if it was flush you would have no adjustment and would not be able to tighten down the clamp as the bearing wore or you needed to make adjustments.

    The bike 'O' ring is a funny shape (from memory :1drink). Have you got the flat edge seated on the steering head and the narrowed section rubbing on the retainer.

    Geek,

    I've had quite a few issues seating that oring bully and haw had several rebuilds where I caught the oring half cocked ad sticking out from user the dust cap. What I did was grease the oring, and set it on the head tube boss, then slip the dust cover over in a twisting motion, and then press the bottom triple up Ito it alas I held it down.

    That might be what's happening, or perhaps emit spec's something different. Who knows. All I can say is the system is more gimmicky, but seals WAY better than the husky, which appears to have no deal whatsoever. :dunno

    Can someone please confirm whether the blind nut (refer to as 27 in this thread?) is a 27mm socket/ring spanner or a 28mm socket/ring spanner?

    I have neither at home at the moment.

    I've measured the blind nut with a set of calipers, it's registering between 27.4mm to 27.6mm.

    It's 27 mm.

    A ring-spanner is better, as you can get at the nut without removing the handlebars.
