I serviced my 2007 RS Rev Coil U-Turn fork and have 5mm ish play in direction of travel ie just moves up and down kind of knocking before damping which is annoying to say the least. I spoke to TF and they recon it could be negitive spring missing but I don't know how I could have lost anything like that. Mate of mine recons it could be an o ring that is hard to see missing from the lowers?
Anyway I would really appreciate any advice anybody could give me or maybe let me know where I could get a drawing of all parts in cut away view or some thing like that.
Thanks guys
Try the service manuals on the [url= http://www.sram.com/en/service/rockshox/ ]SRAM site[/url] for drawings etc - I've found their instructions pretty good. I've had mine apart several times and can't recall any o-rings that could be the problem.
thanks rio, I will look again but have already tried there more than once and couldn't find anything for the coil sprung fork
There is no negative spring on a coil Rev. You've somehow managed to put it back together wrongly, that would be my guess....
thanks at least that sorts out what it is not, I gathered I had put it back together wrong but any ideas what it could be anyone?
Cheers
Have you tightened the bolts at the bottom of each leg properly? Also the spring at the top? Did you remove any seals at all? There's not a lot to go wrong in a RS coil fork, TBH... 🙂
Try this one -
- it's for a Tora but the insides for the coil U-turn are the same as a rev (or at least they're the same as my revs!)
Edit - problems with making the link linky, you may have to cut & paste it...
Thanks again
Stuff I have tried so far
Checking for play in headset
Any loose bolts, lowers or 24mm tops on both damping and spring side
No fork oil leaking
All works fine except for this little bit of play indirection of travel
Think I am going to ring SRAM and try to get a decent drawing and of course when I get time take the lowers off and have a look
I am starting to think that it night be a damper problem?
bugger
personally, i'd strip and rebuild - and just double check the lot against the SRAM diagrams.
Nahh, not a damper problem, I doubt that. It might just be play in the u-turn on the spring. Wind the fork all the way in (Or out) and see if it goes away.
ok thanks guys I will try winding it down then take the lowers off again.
unfortunately i don't have a diagram to work from, checked the SRAM website again and they don't have diagrams just air uturn service manual with pics, doh!
Not specific to you, but this might help
Another one for you to try - the full dealer service manual -
- definitely covers coils...
Thanks again guys, i am thinking it might be an oil problem as I only put 5wt oil in the lowers on spring side. we will see, i'll give it a try
