31. Clamp fork back into bicycle stand. Insert rebound damper back into right side
upper tube, shaft first (fig 31a). 31a 31b
Guide rebound damper shaft through damper seal head at bottom of upper tube,
and pull through (fig 31b).
32. Insert shaft bolt into seal head and thread into rebound
32b 32c
damper shaft end (fig 32a). 32a
Pull shaft bolt down to pull rebound damper shaft
through seal head (figs 32b/32c).
33. With rebound damper shaft in the fully-extended position, measure and pour or inject
33
130cc/ml (+/- 5cc/ml) 5wt suspension oil into upper tube (through crown) (fig 33).
IMPORTANT! OIL VOLUME IS CRITICAL. TOO LITTLE OIL DECREASES DAMPING PERFORMANCE. TOO
MUCH OIL REDUCES AVAILABLE FORK COMPRESSION/TRAVEL, AS WELL AS POSSIBLE DAMAGE TO FORK
FROM COMPRESSION BOTTOM-OUT.
34. Coat the new compression damper u-cup seal with
34a 34b
34c
suspension oil.
REMOTE: SLIDE REMOTE CABLE-STOP CLAMP OVER
REMOTE COMPRESSION DAMPER BODY BEFORE
INSTALLATION INTO FORK. POSITION CABLE-STOP TO
THE 10 O CLOCK POSITION (FROM RIDER S
PERSPECTIVE). SEE (FIG 27d).
Insert compression damper into upper tube, through
34f
34d 34e
crown (fig 34a). Push down and twist slowly on
compression damper, rocking side to side, as it passes
upper tube threads (figs 34b/34c). As soon as the u-cup
seal passes upper tube threads, pull up slightly, then push
back down (figs 34d/34e).
Compression damper should slide easily up and down.
This step ensures the u-cup seal is not folded over, and is
in the correct position inside upper tube. Repeat until compression damper moves with little resistance.
Press the damper down until the upper damper o-ring contacts the upper tube threads. Turn the damper clockwise and thread into
upper tube (fig 34f).. This will protect the upper damper o-ring as it passes the upper tube threads. Do not push straight down; this
will damage the compression damper o-ring seal. Hand-thread top cap into upper tube (fig 34f) and tighten to 60 in-lb with a 24mm
socket wrench (fig 27a).

35. Insert compression damper top cap seal (o-ring or plastic) over top cap (figs 26d/26e).
Place compression knob or remote spool onto compression damper top cap, with knob dial or cable set screw at 3 o'clock position
(figs 26b/26c).
Using external snap ring pliers, secure compression knob or remote spool with external retaining ring (fig 26a).
36. Motion Control Remote Forks: Cable Installation
1) Thread remote cable through cable-stop clamp on crown.
2) Thread cable around compression spool, under cable set-screw, and tighten with 2mm hex wrench. Knob should be positioned
in 3 o'clock position in full-open position.
3) Test PopLoc remote lever function for proper lockout/compression adjust.
4) Adjust cable tension as needed.
LOWER LEG I NSTALLATI ON
37. Pour or inject 15wt suspension oil onto new or clean foam rings, just under dust seal, inside lower leg; each
37a
side (fig 37).
38. Invert fork in bicycle stand to 45-degree angle, upper tubes facing up. Spray upper
38a 38b
tubes with isopropyl alcohol and wipe with a clean rag.
Slide lower leg assembly over and onto the ends of each upper tube. Make sure
both dust seals slide onto the tubes correctly and do not fold under (fig 38a).
Continue sliding lower leg assembly onto upper tubes until you feel the lower
bushings touch the end of the upper tubes. Stop (fig 38b).
39. Measure and pour (or inject...an oil syringe works best) 15cc/ml of 5, 10 or 15wt RockShox suspension oil
39
into lower legs (left and right sides), through both shaft bolt holes (fig 39).
Wipe all excess oil from lower legs.
40. Inspect and clean both damper and air spring shaft bolts and black nylon crush
40a
40a
washers. Replace crush washers and crush washer retainers if damaged. Damaged
or dirty crush washers can cause oil to leak.
Insert rebound damper and air spring shaft bolts into threaded shaft ends, through
lower leg shaft holes, and tighten with a 5mm hex wrench to 60 in-lb (fig 40a).
Insert external rebound damper knob into rebound damper shaft bolt. Push in to
secure (fig 40b). Adjust as desired.

AIR LOSS
" Inspect air piston o-rings. Replace if necessary.
" To avoid air loss, remove DualAir top cap and check oil level inside air chamber, every 25 to 50 riding hours. If there is little or
no oil on top of air piston o-ring, pour 3 to 5cc RockShox 15wt suspension oil into air spring chamber. Oil will keep air seal
lubricated.
" Inspect schrader valve assembly. Replace if damaged or malfunctioning. Clean if clogged.
LOSS OF, OR VARIANCE IN DAMPING
" Inspect all damper o-rings. Replace and lubricate.
" Inspect damper oil volume. Remove damper top cap/compression damper assembly. Add or remove oil as needed.
" Remote: Inspect remote cable tension. Cable may stretch, or become loose. Loosen cable screw, tension cable and tighten.
Test. Adjust as needed.
BUSHING PLAY
" Inspect and replace worn bushings. Bushings are a wear and tear item, and need to be replaced after approximately 100 to 200
riding hours, depending your riding style, condition, riding time and body weight. If you ride a lot, check those bushings!
" See the 'Bushing Installation' guide at www.rockshox.com for procedures.
OIL LOSS
" Inspect the air piston o-ring for air bypass. If there is a repeated loss of air pressure, air may be the cause of oil loss at the left
dust seal.
" Inspect your shaft bolt crush washers. Replace if worn or damaged.
" Inspect your top cap o-rings. Replace if torn or knicked.
