    2013 RS Revelation Service Questions

    Fork details:

    2013 Rockshox Revelation RC3 from 2013 Stumpjumper FSR Comp EVO.

    -150mm
    -Air sprung w/ Motion Control damper

    Documentation:

    -2011 Revelation Technical Manual: http://cdn.sram.com/cdn/farfuture/AI...cal-manual.pdf

    -2014 Fork Oil Charts: http://cdn.sram.com/cdn/farfuture/4z...art_2014_0.pdf

    Question 1:

    I have been experiencing a top out clunk under the first cm or so of travel. From what I understand this is caused by lack of oil in the motion control damper. After a bit of research, I discovered that RS specifies different quantities of oil in both the 2011 tech manual (under the regular motion control damper spec - 123mm) and the 2014 fork oil charts (134mm). Could this lack of oil be from whoever assembled the fork using the 2011 manual and not the 2014? Which manual should I use if I service my fork?

    Note - The 2011 fork oil charts not supplied state the same quantity as the 2011 technical manual.

    Question 2:

    In the assembly procedure for the lower legs in the 2011 tech manual, it states that if I have "hollow bottom fork legs" the process is done differently. I was wondering how I tell if my fork legs are "hollow" as they say, besides the obvious looking into them lol. I suspect this is some kind of technology which I wasn't able to find on the RS website under specifications.

    Question 3:

    Has anyone used 15wt oil in the fork lowers where it is specified to use 5wt? Would be a cost saver if people have done this without any issues.

    Note - The damper takes 15wt.

    Thanks in advance! -Mike

    - Open the damper and make sure the oil level is above the compression piston.

    - The Revelation does not have hollow legs.

    - Yes. The oil is only there for lubrication. In fact, it's pretty common to run Mobil1 motor oil or ATF since it lubricates better.

    I just realized in my 3rd question I stated the manuals specifies 5wt when in fact it says 15wt. That being said is it possible to use 5wt instead? By the sounds of your answer that would be fine also.

    Also for opening the damper; can I do so without removing the lowers? Which part of the compression damper is the compression piston? Is it possible to simply top it off with the legs still on?

    The SID and some 29er forks have hollow bottom fork legs. The Rev does not.
