Knocking Totem Fork

edited April 2008 in MTB workshop & tech
I was cleaning my bike today when i noticed a slight knocking noise when i depressed the fork. Thinking it may just be a loose headset i tightened it up and also gave it a good clean. Once back together i tried again and again the same knocking noise. I turned the bike upside down and can hear the noise when depressing the fork. I also noticed a small amount of oil on one of the sliders after repeatedly depressing it.

Does anyone have any idea what this may be and how to fix it. It is a Rockshox Totem Coil not sure of the age of it as i bought it second hand in december 2007.

    Its ok the bloke at TF tuned knew exactly what the problem was and told me how to fix it. I was surprised when he didnt try to get me to send them to him and asked him why. His reply was " i hate to rip people off and always do a good job"

    TF Tuned - Top Blokes, you get my vote, recommendation, and my custom when i need it. Thanks

    Before you ask - no i dont work for them i just like honest people.

    What was the prob? Often the coil rubbing the stanchion, or not seated properly.

    TF tuned said it was the spring knocking against the side of the stanchion as you guessed which create a flat spot in the fork. Also the seals are on the way out but he said they are waiting on a new type of seal they had prototypes of recently and they were so good recommended waiting until they were in if i wanted them changing. They are going to do a newsletter when they come in. He also said that the forks can be used as they are and told me how to do an oil change. Pretty good advice.

    I did an oil change on mine the other day. I used a 2.5wt oil in the damper instead of the usual 5wt. You wouldn't believe the difference in the performance, small bump absorbtion is awesome now. Had to wind the Rebound adjuster in a little more than usual to get decent control though.

    Best mod I've done to the bike. :D

    My spring knocks at the very bottom of the stroke also, how do you cure it?

    If you take the spring out you will see a wrap of rubbery stuff around it. This is what stops it rubbing (and is colour coded for the weight). Sometimes they slip, should be in the middle (ish), or you can make your own to make it bigger.

    How do you make your own? What material do you use ?

    Very thin rubber! I'm sure you'll find something ;-)

    Narrow roadie tube cut into sections can work.
