VANILLA R

Note:  Some of these photos, while adequately serving to demonstrate service procedure, may not accurately show the fork model.

Disassembly

It's not necessary to remove the R Topcap to disassemble the topcap assembly. If you do not wish to remove the rebound knob, skip to step #3.

Before removing the R Topcap, you must first remove the retaining nut at the bottom of the fork leg. The retaining nut will be removed in the next step.

Remove the R Topcap

1. With a hex key wrench, remove the hex key on top of the red rebound knob.
   
   
2. Remove the rebound knob by lifting it.
   
   
3. Unscrew—but do not remove—the damper topcap with a 26 mm 6-point socket. Be careful not to slip and damage the wrench flats. You may need to grind down the socket so that it properly grips the wrench flats on the topcap.
   
    
4. Leave the topcap assembly on. Secure your fork so that the fluid inside of the fork does not spill out.
   • After loosening the R Topcap assembly, you are now ready to remove the bottom nut on the damper, which will allow you to fully remove the R Damper assembly from the lower leg assembly.
   • Place an oil pan underneath the fork before loosening the bottom nut.
   • Make sure the topcap assembly is screwed in a few turns since you will need to turn the fork upside-down to access the bottom nut. You will not want suspension fluid spilling all over your new Hush Puppies.

Remove the R Damper

1. Using a 10 mm socket, remove the bottom nut.
   
   
2. Screw the bottom nut back on two full turns. Using a plastic faced hammer, gently strike the bottom nut to release the damper assembly.
   
   
3. Holding the fork over an oil pan, remove the bottom nut and crush washer. If the crush washer isn't attached to the nut, check the bottom of the lower leg; it might be stuck there. Suspension fluid should flow out.
   
   
4. Making sure the fork is right-side up, remove the topcap.
   
   
5. Pull up on the topcap and remove the R Damper assembly.
   
   

Remove the Preload Topcap

1. Before removing the Preload Topcap, turn the preload knob (shown below) fully counterclockwise. This releases the load on the coil spring.
   
   

   CAUTION:  There is a small amount of suspension fluid in the left leg. Screw in the topcap at least 2 full turns before turning the fork upside-down, to prevent the fluid from spilling out.

2. Unscrew the preload topcap with a 26 mm 6-point socket. Be careful not to slip and damage the wrench flats. You may need to grind down the socket so that it properly grips the wrench flats on the topcap.
   
    

Remove the 32 mm Vanilla Spring

1. The Preload Topcap was loosened in the previous step. You can now fully unthread the topcap to expose the coil spring.
   
   
2. Pull out the coil spring.

   Note:  The 2007 VANILLA 140 does not have a shorter travel option. Therefore, you should not find any travel spacers on top of the coil spring.

   
   
3. Sometimes the plunger shaft will come out when the coil spring is pulled out. If that is not the case, turn the fork upside-down and allow the plunger shaft to drop out.
   
   

Remove the Crown Steerer Assembly

1. Both the damper shaft and air spring shaft should be dislodged from the lower legs, allowing you to remove the lower leg assembly. Drain the lower leg assembly into an oil pan before putting it aside.
   
   
2. Clean the crown/steerer/upper tube assembly with parts cleaner.
3. Inspect the assembly for any nicks, cuts, scrapes, scratches or gouges, and replace if necessary.
   • The assemblies that normally prevent the removal of the lower legs should already have been removed.
   • Removal of the lower legs should be done with the fork secured in a bike stand and over an oil pan.

Remove the 32 mm Lower Assembly

1. Making sure the fork is secured in a bike stand or soft-jawed vise and over an oil pan, turn the fork upside-down.
2. Remove the topcap assemblies from both sides of the fork, and let the oil drain out.
   
   
3. If not already done, remove all base valve bolts and/or knobs.
4. Gently pull up on the lower legs to fully disengage them from the upper tubes.
   
   
5. Drain any remaining fluid from the lower legs into an oil pan.
   • After removal of the lower legs, it is a good idea to replace the dust wipers and foam rings
   • When possible, the bicycle/fork should be stored upside-down to keep the dust wipers and foam rings lubricated.

Remove the Dust Wipers from the Lower Assembly

1. Using an 18 mm open-end wrench, pry up the dust wipers. Be careful not to scratch the ID of the lower legs.
   
   
2. After the dust wipers are removed, the foam rings will be visible. Lift them out of the lower legs. If they cannot be located, check under the dust wipers; they might be stuck underneath them.
   
   

   You can get a general sense of the condition of the fork by examining the foam rings. Dry foam rings indicate a lack of fluids or, possibly, a leak. Dirty foam rings may indicate a faulty dust wiper. In either condition, the anodizing on the upper tubes should be examined. If the anodizing has worn off due to insufficient lubrication, replacement of the crown/steerer/upper tube assembly might be necessary.

   After examining the dust wipers and foam rings, they can be discarded and replaced using the following replacement kits:

   FOX 32 mm Dust Wiper Kit (FOX P/N: 803-00-079)

   Lower Leg Bushings:

   FOX Racing Shox recommends that you have your bushings serviced at a Factory Authorized Service Center. Refer to http://www.foxracingshox.com/fox_tech_center/service.htm.

   Bottom-out Bumpers:

   • Bottom-out bumpers are technically not a serviceable item, so they rarely need to be replaced.

   Dropouts:

   • Over time the knurled surfaces of the front wheel hub and quick-release skewer wear out the dropout region of the lower leg (see Dropout photo below).
   • Inspect and measure the thickness of the dropouts every 6 months or 100 hours. Ensure that any point on the surface is above the minimum specification of 6.20 mm (see Measure Dropout photo below).
   • Replace the lower leg assembly if the dropout thickness is at the minimum specification or less.

Replacing the Dust Wipers

Discard the original dust wipers and foam rings, and install new ones from the FOX 32 mm dust wiper kit (PN 803-00-079).

1. Presoak the new foam rings in 10 wt. damper oil.
   
2. Place the oil-soaked foam rings in the lower legs as shown.
   
3. Install the new dust wipers over the foam rings and seat them fully into place using thumb pressure, as shown. You can apply a thin coat of oil to the sides of the dust wipers, to ease their installation.
   

   Note:  be sure to seat the dust wipers into the lower assembly completely and evenly.

4. While tilting and gently pressing the upper tubes into the lower leg assembly, push past the newly installed dust wipers and foam rings, sliding the lower leg assembly onto the crown steerer assembly part way.
   

   Tip:   slightly stretching the outer lip of the dust wipers during this step won't risk causing damage to them.

Damper Cartridge Service

For specific service instructions for internal assemblies, see service procedures for the 2007 32 mm R cartridge.

Note:  Before proceeding with any cartridge service procedures, be sure that you have drained all oil from the damper cartridge.

Go to Damper Cartridge Oil Removal for more information about this procedure.

Install the 32 mm Vanilla Spring

1. Drop the spring plunger shaft into the left upper tube.
   
   
2. The bottom of the plunger shaft should protrude from the bottom of the lower leg. Place a new crush washer on the shaft, then screw the bottom nut on.
   
    
3. Torque the bottom nut to 50 in-lb (5.65 N-m) using a 10 mm socket and torque wrench.
   
   
4. Turn the fork right-side up, then drop the coil spring into the upper tube. (Make sure you are inserting the proper-rated coil spring into the fork. If the rider wishes to switch springs, now is the time to do it. Consult the Coil Spring Guidelines table below for spring settings.)

   Note:  The 2007 VANILLA 140 does not have a shorter travel option. Therefore, you should not find any travel spacers on top of the coil spring.

   
   

   COIL SPRING GUIDELINES
   FOX Part #	Approximate Spring Rate	Color Code	Travel (mm)	Rider Weight lbs. (kg)
   039-05-080	40.6 lb/in	Black	140	<90–115 (40.8-52.2)
