While FOX recommends using the Specialized FLOAT Genie specific damper and air spring rebuild kit (PN: 803-04-014) when servicing the FLOAT Genie shock, the standard FLOAT rebuild kit (PN: 803-01-992) may be used to perform a complete damper service. The standard FLOAT air sleeve kit (PN: 803-01-993) may be used to service the air spring, but it will not contain all of the FLOAT Genie specific bearing housing assembly and air sleeve seals needed to perform a full factory level service.

WARNING: Always wear safety glasses and protective gloves during service to prevent potential injury. Failure to wear protective equipment during service may lead to SERIOUS INJURY OR DEATH.

WARNING: FOX products should be serviced by a qualified bicycle service technician, in accordance with FOX specifications. If you have any doubt whether or not you can properly service your FOX product, then DO NOT attempt it. Improperly serviced products can fail, causing the rider to lose control resulting in SERIOUS INJURY OR DEATH.

WARNING: Modification, improper service, or use of aftermarket replacement parts with FOX forks and shocks may cause the product to malfunction, resulting in SERIOUS INJURY OR DEATH. DO NOT modify any part of a fork or shock, including the fork brace (lower leg cross brace), crown, steerer, upper and lower leg tubes, or internal parts, except as instructed herein. Any unauthorized modification may void the warranty, and may cause failure or the fork or shock, resulting in SERIOUS INJURY OR DEATH.

WARNING: FOX suspension products contain pressurized nitrogen, air, oil, or all 3. Suspension misuse can cause property damage, SERIOUS INJURY OR DEATH. DO NOT puncture, incinerate or crush any portion of a FOX suspension product. DO NOT attempt to disassemble any portion of a FOX suspension product, unless expressly instructed to do so by the applicable FOX technical documentation, and then ONLY while strictly adhering to all FOX insturctions and warnings in that instance.

WARNING: Never attempt to pull apart, open, disassemble, or service a FOX shock that is in a "stuck down" condition. A "stuck down" condition results from a failure of the dynamic air seal (located between the positive and negative air chambers within the non-EVOL shock air sleeve), resulting with the negative chamber retaining a higher pressure than the positive chamber. To test whether the shock is in fact "stuck down":

  1. Remove the air cap and depress the Schrader valve, to completely release air pressure from the positive chamber of the shock.
  2. If the shock body retracts into the air sleeve near bottom-out after the air is released from the positive chamber, attach a FOX high pressure pump and pressurize the shock to 250psi (17 bar).
  3. If the shock does not fully extend, it is in a "stuck down" condition.

Any attempt to service FOX air shocks in the "stuck down" condition can lead to SERIOUS INJURY OR DEATH. Contact FOX or an Authorized Service Center for repair.

Disassembly

img/help/page2913-0UXW/IMG_8093-m.jpg

Step 1

Clamp your shock in a soft-jawed vice. Remove the black air cap and thread on your FOX shock pump. Slowly release all air from the main air chamber with your pump, then remove the pump.

img/help/page2913-0UXW/IMG_8097 copy.jpg
img/help/page2913-0UXW/IMG_8149-m.jpg

Step 6

Using a Torx T8, unthread the air fill cap counter-clockwise to access the air valve. Release the IFP pressure by depressing the valve core inside the body.

img/help/page2913-0UXW/IMG_8158-m.jpg

Step 7

Remove the glide band from the bearing housing to access the bleed screw. Use a 2mm hex wrench to slowly remove the bleed screw by turning it counter-clockwise. Use a magnet to remove the ball from under the bleed screw. Remove any Travel Spacers (if present) by unthreading counter-clockwise and removing the two screws with a 2mm hex wrench. Unthread the bearing assembly from the shock body with custom spanner tool ( PN: 398-01-114) by turning it counter-clockwise.

img/help/page2913-0UXW/IMG_8168-m.jpg

Step 8

Remove the shaft assembly from the body and pour out the damper oil. Remove the IFP by threading the air fill adaptor (PN: 803-01-985) clockwise into the body. Carefully apply air pressure with your pump to remove the IFP. Inspect the body for damage or excessive wear. Remove your shock pump, leaving the air fill adaptor threaded into the shock body.

img/help/page2913-0UXW/IMG_8174-m.jpg

Step 9

Remove the IFP o-ring and inspect the gland on the piston for any damage or contamination. Apply Slick Honey grease to the new IFP o-ring from the replacement seal kit, and install it on the piston.

img/help/page2913-0UXW/IMG_8176.jpg
img/help/page2913-0UXW/IMG_8178-m.jpg

Step 10

Apply a very thin film of Slick Honey to the inside of the shock body, then insert the IFP with it's slot facing up. Adjust your calipers to the correct IFP depth for your shock. The FLOAT PSA shock uses an IFP depth of 2.530 in (64.26mm) +/- 0.020in. Use your caliper to push the IFP down to it's appropriate depth. Remove the air fill adaptor.

Eyelet Rebuild

img/help/page2913-0UXW/IMG_8225-m.jpg

Step 1

Use a 1.5 mm hex wrench to remove the set screw from the top of the eyelet assembly. Remove the Float lever assembly by pulling it out of the eyelet. Be careful not to lose the detent ball from behind the lever assembly. Remove the detent bearing and spring with a magnet. Clean the bare eyelet and set aside

img/help/page2913-0UXW/IMG_7744-m.jpg

Step 2

Use a 1.5mm hex wrench to unthread the rebound knob set screw counter-clockwise. Remove the red rebound knob by pulling it away from the lever assembly. Remove the cam by pulling it out of the lever assembly from the back. Use 1.5mm hex wrench to remove the rebound set screw from eyelet by turning it counter-clockwise. Be carefull not to lose the detent ball and spring. Remove the rebound gear from the inside of the eyelet using a magnet. Use a thin shim to remove the small retaining ring that holds the black adjuster to the blue compression selector lever.

img/help/page2913-0UXW/IMG_7753 copy-m.jpg

Step 3

Insert the black adjuster into the blue compression selector lever followed by the spring, spring retainer, and retaining ring. Compress the spring against the blue compression selector lever to make room to install the retaining ring. Reinstall the red rebound knob and tighten the 1.5mm set screw clockwise to 5 in-lb (0.6 Nm) torque. Coat the cam and spring with a film of waterproof grease such as Sta-Lube SL3125 or Ultraplex LT2.

img/help/page2913-0UXW/IMG_8234-m.jpg

Step 4

Insert the rebound gear into the eyelet then insert the greased detent spring into the small hole in the face of the eyelet, followed by the detent ball. Carefully insert the lever assembly into the eyelet without dislodging the detent ball and spring. Compress the detent spring by pushing the lever assembly into the eyelet, then install and gently tighten the set screw in the top of the eyelet fully, then back it out 1/4 turn.  Insert the rebound detent ball and spring on the side of the eyelet, then install and gently tighten the set screw.

NOTE: Test out all functions of the shock on a hand dyno to verify correct assembly. 

When adding air to the air chamber, it is important to equalize the positive and negative air chambers by slowly compressing the shock through 25% of its travel 10-20 times after every 50psi addition.

  • Adding air to the shock without periodically equalizing the air chambers can lead to a condition in which the shock has more pressure in the positive chamber than the negative. In this condition the shock will be very stiff and can top-out. You can equalize the air chambers by slowly compressing the shock until you feel and hear a transfer of air. Hold the shock at this point for a few seconds to allow the air to transfer from the positive to the negative chamber.
