LazyLab Posted April 30, 2014 Posted April 30, 2014 Need to service my fork, but oil volumes changed between the two years. Anyone know how to tell the difference between the two models? There was a change in the damper design and stantion length. Guy at Cape Cycles explained how to use the manufacturing code, but the linebwas not great.
droo Posted April 30, 2014 Posted April 30, 2014 Measure the length of the damper from the bottom of the flange on the topcap to the middle of the o-ring on the damper foot, then fill the damper tube to 10mm above that level - the oil level on most current RS dampers is 90mm. Make sure you cycle the damper a few times before measuring to get any air trapped below the rebound piston out. LazyLab 1
ThePubSA Posted April 30, 2014 Posted April 30, 2014 Look in the back of the fork arch, ... in the little grooves on the top left,.. it will have a 11 or 12 ,.. but that is on the lowers,..so unless your uppers have been changed thats the year model
ThePubSA Posted May 5, 2014 Posted May 5, 2014 Thanks for the advice. It was 2012!Ya and sure its just a tad easier then droo's method

I have a fork that I don't know if it is a SID or Reba...says Sid on the outside but when you open it, it looks like a Reba on the inside.....

Too low and there's no damping in the initial part of the stroke, too much and there's nowhere for the displaced oil to go and you get hydraulic lock. RS dampers need 10mm of oil above the damper foot. Hope this explains it a bit better, my teaching skills aren't the finest.
