img/help/page1-wx57i1/IMG_6704.jpg


img/help/page1-wx57i1/IMG_6705-m.jpg

Step 19

Make sure that the check shim (the shim under the piston assembly) can move freely as isn't pinched between the piston and the end of the damper shaft. Once sure that the check shim is not pinched, torque the piston bolt to 55 in-lb (6.2 Nm).

img/help/page1-wx57i1/IMG_6705.jpg
img/help/page1-wx57i1/IMG_6706.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_028-m.jpg

Step 20

Replace the piston glide ring.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_028.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_029-m.jpg

Step 21

Remove the retaining ring and bladder retainer to free the bladder ring, being careful not to scratch the cartridge body.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_031.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_032-m.jpg

Step 22

Push the bladder ring towards the topcap, as indicated below.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_032.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_033-m.jpg

Step 23

Be sure NOT to clamp the smooth portion of the body. Always clamp below this section to prevent damage to the bladder sealing surface.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_033.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_034-m.jpg

Step 24

Internally support the coupler with a 5 mm hex inserted through the body from the bottom. Remove the topcap from the bladder and cartridge body assembly with a 6-point chamfer-less 26 mm socket (28 mm socket for 2013 34 mm forks).

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_034.jpg


Note: At this point the cartridge can disassemble in two different ways. Pay close attention to the instructions for your specific scenario.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_035-m.jpg

Scenario A: Piston Inside Topcap

If your compression piston remains inside the topcap, use the inner Fox piston removal tool (398-00-348) and a 6-point chamfer-less 26mm (28mm for 2013 34mm forks) to remove the piston from the topcap.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_035.jpg

img/help/page1-wx57i1/Topcap_alt_004.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_036-m.jpg

Step 25

Inspect the compression shim stack and set aside in order. Replace any damaged parts as necessary. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_036.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_042-m.jpg

Step 26

Using a blunt tool iniserted through the bleed port, press the flow divider out through the bottom of the topcap. Use your forefinger for support, keeping it square with the topcap as you push it out.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_042.jpg

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_043.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_044-m.jpg

Step 27

Replace the o-ring on the compression adjuster rod. Make sure the flow plate remains flush with the flow divider as you set this assembly aside for now.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_044.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_045.jpg


img/help/page1-wx57i1/FIT_CTD_w-outTrail-Adj_052-m.jpg

Step 28

The only two points of potential oil leakage through the topcap are shown below. Be sure to replace both of these o-rings!

img/help/page1-wx57i1/FIT_CTD_w-outTrail-Adj_052.jpg


Reassembly

img/help/page1-wx57i1/FIT_CTD_w-outTrail-Adj_056-m.jpg

Step 1

Install the flow divider assembly squarely into the topcap, making sure to align and insert the dowel pin into the hole indicated below. 

img/help/page1-wx57i1/FIT_CTD_w-outTrail-Adj_056.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_057-m.jpg

Step 2

The flow divider is completely installed and squarely seated only when you are able to see an even smooth band of unthreaded wall between the flow divider and topcap threading, as indicated below. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_057.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_058-m.jpg

Step 3

To replace the bladder, first separate the bladder from the threaded coupler at the top of the cartridge body and slide the bladder and ring assembly off the cartridge body, as shown. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_058.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_059.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_060-m.jpg

Step 4

Remove the bladder ring from the original bladder. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_060.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_061-m.jpg

Step 5

Grease the inside and outside of the bladder at both ends and install the bladder ring as shown.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_061.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_062.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_063-m.jpg

Step 6

Slide the new bladder with bladder ring over the cartridge body and onto the coupler. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_063.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_065-m.jpg

Step 7

Clamp the cartridge body so the coupler is facing up. Reinstall the shim stack in its original configuration.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_065.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_064b.jpg


Installing the compression piston backwards will require a new topcap assembly in addition to various other small cartridge parts. Make sure you install the compression piston as shown (with the bevel facing up toward the topcap).

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_067a-m.jpg

Step 8

Be sure to place the compression piston in its correct orientation (the beveled end oriented towards the topcap). Apply a liberal coating of slick honey on the outside of the bladder before installing the topcap assembly. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_067a.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_067-m.jpg

Step 9

As you thread the topcap onto the compression piston, apply gentle upward pressure on the bladder and bladder ring. This pressure helps to force the bladder up into the topcap as you are threading it down. If necesarry, the bladder installation tool (PN: 398-00-321) can be used to help tuck the bladder into the topcap. Allow the bottom end of the bladder to rotate around the cartridge body as you thread to prevent the bladder from twisting.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_067.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_068-m.jpg

Step 10

When the topcap is threaded on, make sure the bladder is seated evenly into the topcap assembly with no distortions. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_068.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_069-m.jpg

Step 11

Tighten the topcap onto the bladder and cartridge body assembly to 75 in-lb (8.5 Nm) torque. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_069.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_070-m.jpg

Step 12

Place the bladder and cartridge body assembly into the second largest hole in the #2 clamps as shown; loosely resting the bladder ring on the clamps, no clamping pressure applied to the bladder ring. While gently tugging the topcap from below, you will seat the bladder in the bladder ring deep enough to install the bladder retainer and retaining ring.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_070.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_071.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_071b.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_072-m.jpg

Step 13

Install the damper shaft assembly into the cartridge body assembly. With a 13 mm crows foot, tighten the seal head into the cartridge body to 75 in-lb (8.5 Nm) torque. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_072.jpg


Hand Bleeding the Cartridge

This section can be skipped by those that have access to a vacuum/fill machine (Andreani).

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_073-m.jpg

Step 1

With the cartridge fully compressed, thread the bleed adapter tool (PN 803-00-809) into the bleed hole in the topcap. Place the rubber tip of the Fox FIT bleeder tool (PN 803-00-276) into the adapter. Fill the bleeder tool with Fox red oil until full.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_073.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_074.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_075.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_076-m.jpg

Step 2

Repeatedly squeeze and release the bladder to force out any air. Next, cycle the shaft slowly down to full extension, drawing oil into the cartridge. If bubbles are present in the syringe oil, wait until the bubbles have risen to the top before drawing clear oil down into the cartridge.

Repeat the squeeze, cycle, and wait process described above, until air bubbles stop appearing in the syringe as you squeeze and cycle the cartridge. 

Do not let the oil level in your syringe drop to the point where you can ingest air into the cartridge. Add oil to the syring as necesarry.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_076.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_077-m.jpg

Step 3

The bleed process is complete when air bubbles are no longer produced as you squeeze the bladder and cycle the cartridge. Once complete, remove the bleed adapter tool and top off the bleed hole with 10wt. red oil.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_077.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_078.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_079-m.jpg

Step 4

Insert the blowoff piston and spring into the bleed hole. Fill the recess in the underside of the bleed screw with a small amount of Slick Honey and install it using the 2.5 mm hex driver. This completes the hand bleeding section. At this point, you should cycle the damper and verify that there is no sound of trapped air inside the cartridge. Repeat the bleed process if necessary to remove any trapped air from the cartridge.

Final Topcap Reassembly

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_083-m.jpg

Step 1

Thread the set screw for the blue CTD lever a few turns into the compression adjustor rod. This enables you to pull the rod upwards for optimal installation of the detent ball with spring that follows. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_083.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_084-m.jpg

Step 2

The bleed adapter tool (or a small socket) is handy for holding the compression rod detent ball in place as you install its spring. 

Compress the detent spring with a pick tool or flat driver while pushing the compressed spring down into the slot with a blunt tool.

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_084.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_085.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_089-m.jpg

Step 3

Install the detent spring retainer plate followed by the tolerance spring onto the compression adjuster rod. 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_089.jpg


img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_090-m.jpg

Step 4

Install the cartridge into the fork, tightening to 220 in-lb torque with a 6-point 26 mm chamfer-less torque socket for 32mm forks (28mm for 2013 34mm forks). 

img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_090.jpg
img/help/page1-wx57i1/FIT_CTD_wTrail-Adj_091.jpg


img/help/page1-wx57i1/CTD_pickupix_001a-m.jpg

Step 5

Use the compression selector lever to find the middle detent setting (trail mode). Remove the compression lever and reinstall it, with the lever pointing to the three o'clock position from the rider's perspective. Hold the lever as shown when tightening the set screw with a 2.5 mm hex driver to 11 in-lb (1.2 Nm) torque.

img/help/page1-wx57i1/CTD_pickupix_001a.jpg


img/help/page1-wx57i1/v20-m.jpg

Step 6
