INTRODUCTION
This manual is intended to guide the user through basic service of Manitou front forks. Service is
supported by the identification of common parts and assemblies that have been assembled into
Service Kits. The purpose of this manual will be to describe conditions that may drive the need
for service and to provide installation instructions for the kits.
Due to the time-consuming nature of suspension fork service, at this time our primary focus is to
offer service kits that minimize the amount of downtime and labor involved.
Important information is highlighted in this manual by the following notations:
WARNING
Failure to follow WARNING instructions could result in severe injury or death to the
person inspecting or repairing the suspension fork or the user.
CAUTION
A CAUTION a caution indicates special precautions that must be taken to avoid damage to
the product.
NOTE
A NOTE provides key information to make procedures easier or clearer
GENERAL WARNING: Suspension forks by design can contain preloaded springs, gases
and fluids under extreme pressure and warnings contained in this manual must be
observed to reduce the possibility of injury or possible death. Following these
instructions can help you reduce the risk of being injured. Any questions in regards to the
information in this manual should be directed to Manitou Customer Service at (888) 6863472.
WARNING: Suspension forks uses preloaded spring(s) to provide compression spring
resistance. This system must be relieved of preload prior to servicing. Failure to relieve
air pressure could result in injury or possible death.
CAUTION: Suspension forks use precision machined aluminum and other soft alloy components.
Using correct tools for assembly is essential to prevent damage.

FRONT SUSPENSION TERMINOLOGY
Air Cap – Top cap that threads into top of air/spring leg (this is the left leg of the fork as you are
seated on the seat). Forks may be controlled with an air/spring or a coil spring. The air cap
contains the Schrader Valve, which is used to control the spring rate or SAG of air forks.
Air Spring – A mechanism that is used to control the SAG of an air fork.
Arch – A support that connects the two outer lower legs of the casting so as to keep them moving
in unison.
Boss – The word used to describe an outer casting that has brake posts for V-brakes or
cantilever brakes.
Bottom Out Bumper – A rubber or elastomer device that absorbs the shock that occurs when a
suspension is compression to its limit.
Bushings – A cylindrical sleeve between a fork stanchion tube (inner leg) and a fork outer
casting (slider), which facilitates the sliding movement between these two parts.
Cartridge Damping – Provides better oil flow, bump sensitivity, and improved damping control in
long travel applications.
Coil Spring – A coiled piece of metal that acts as a spring to help suspend a fork.
Compression – The phase of the suspension operation in which the wheel travels up, or travels
closer to the frame. The suspension forks reaction to a bump in the trail.
Compression Damping – Restriction of the rate that the suspension compresses under load.
Crown Steer Assembly – the stanchion legs (inner legs), the fork crown, and the steer tube
pressed together as one assembly. This assembly is then finished by adding all of the fork
internals and then outer casting (slider).
Damping – A function that modifies the rate of suspension compression or rebound.
Detent – An indentation that causes a rotating adjuster to stop at fixed increments.
Drop Out – The end of an outer casting (slider) where the wheel attaches.
Dust Boot – Usually a piece of rubber in the shape of a cylinder with baffles to allow it to
compress as the fork compresses through its travel. Its function is to help keep dirt and water
from getting into the inner legs of the fork.
FRONT SUSPENSION TERMINOLOGY (CONT.)
FFD – Fluid Flow Damping. A Manitou patented low cost oil damping system. The compression
damping is non-adjustable and the rebound damping may be non-adjustable or adjustable
damping.
Fork Crown – The component that joins the stanchion tubes (inner legs) to the steer tube of the
fork.
Hydraulic Fork Oil – Oil used in suspension designs to provide damping. It has special
characteristics that determine how it reacts when exposed to compressed air, how it changes
viscosity when its temperature changes, and how it moves through valves.
4
Hydraulic Lock Out – a condition caused when the mixture of air and damping oil is out of
balance. It is caused when there is too little air space in a chamber, not allowing the fork to
compress through its travel.
IS2 Integrated Stem System – integrates top triple clamp with bar mount, eliminating the need
for a stem. Flip Flop mount allows for 45mm or 60mm stem measurements and spacers allow bar
height adjustments. Includes shims for both 31.8 and 25.4mm handlebars.
Infinite Travel System (IT) – A handle-bar mounted air travel adjust system that allows the rider
to change the fork travel (and ride height) without a spring rate change. The travel can be
changed from full compression to full rebound and at any place in between.
Intrinsic Damping– speed sensitive SPV based damping system for long travel applications.
Provides better sensitivity to small bumps and superior bottoming resistance.
Lock Out – a special function that restricts the compression of the fork from moving. It is
generally controlled by an external knob that is activated when a rider does not want the fork to
move, thus eliminating extra energy needed to overcome the bobbing forces of the fork.
MCU – (Micro-Cellular Urethane) Special urethane that is filled with tiny air cells that act like
springs when the elastomer is compressed.
No Boss - The word used to describe an outer casting that has no brake posts for V-brakes or
cantilever brakes. This casting is to be used for disk brakes only.
No Tools Hex Lock Axle – Update of patented Hex Lock through axle provides simple and
effective wheel removal system without requiring tools. Features dual quick release to remove
pinch pressure and the axle is tighten and loosened with hand turned side tension bolt.
Oil Damping – A system that uses the resistance to oil flow through holes in a valve to provide a
means to alter the rate of suspension compression or rebound.
Oil Level – The level of damping oil needed for the optimal damping performance of a
suspension. It is measured as the air space distance between the top of the stanchion leg (inner
leg) and the height of the oil inside of the leg. The fork must be completely extended in order to
get an accurate measurement.
O-Ring – A soft, flexible neoprene or Buna rubber ring with a round cross-section, which is used
for sealing and retention.
FRONT SUSPENSION TERMINOLOGY (CONT.)
Oil Weight – A description of the relative viscosity of oil, such as hydraulic oil. Oil with low weight
numbers (5wt or 7wt) flows through the valving with less resistance than higher weight numbers
(10or 15 wt).
One Point Five Standard - 1.5 inch interface standard for frame head tubes, headset, cups,
stem, and steer tubes which allows for the lightest weight and strongest design in 170mm single
crown forks. This design greatly improves the control and steering precision of the fork. It is used
predominately on forks with longer travel and the intended use is for more hardcore, extreme
riding.
Outer Casting – (see Slider)
Preload – A condition of compressing a spring or elastomer before the operating loads are put on
the suspension, so that it provides a stiffer spring rate.
5
Piston – In front suspension, the part of the damper that slides back and forth inside of the
damping leg that houses the valves. It can also refer to the air piston in the air/spring assembly
that slides back and forth compressing the air, thus causing a change in the spring rate of the
suspension.
Porosity – The condition or property of having pores in a material that will allow gas or liquid to
pass through it.
Quad Ring seal – New seal that replaces standard o-rings in designs that require more efficient
air and oil sealing methods.
Rebound – The phase of the suspension operation in which the wheel returns to its original
position on the ground after compression.
Rebound Damping – Restriction of the rate that the suspension rebounds when the compression
load is relived.
Remote Lock out system – A handle-bar lever actuated system that controls the lock out
function on front and rear suspension products.
Reverse Arch Technology – Also known as RA. It is a system that is designed to move the arch
of a fork to the backside of a fork, rather than the conventional front position. It was designed to
provide greater rotational torque strength to an outer casting (slider), without adding additional
weight to the fork.
Sag – The amount a suspension fork compresses at rest with a normal load (rider’s weight).
Schrader Valve – Valve used to introduce air into a chamber.
FRONT SUSPENSION TERMINOLOGY (CONT.)
Seal – A part, usually neoprene rubber or Buna, that keeps contaminants out and/or working
fluids in.
Semi Bath – A lubrication system that uses a lubricating oil to keep the bushing surface and
stanchion legs (inner legs) as friction free as possible during movement of the stanchion legs.
Spring Rate – The rate at which the resistance of a spring increases as it is compressed.
Slider/Outer Casting – The tube (outer casting leg) of the suspension fork that0. remains fixed to
the wheel. It slides up and down on the stanchion leg (inner leg).
Stanchion Clamps - (Double-Triple Clamps) the portions of the fork crown that clamp around the
stanchion legs above and below the head tube of the bicycle frame on specific long travel
applications.
Stanchion Legs – The suspension tube (inner leg) fixed to the fork crown. It remains stationary
during the operation of the suspension.
Steer Tube – The long cylindrical tube that extends from the top of the fork crown. Its function is
to be inserted into the bicycle head tube and attach the suspension to the bicycle frame.
Thru Axle – (Hex-lock) A device used for mounting a thru axle hub to special outer legs that are
not made for standard quick release hubs. Manitou’s Hex-lock (thru axle) system is a special
patented system utilizing a hex shaped end that increases the stiffness of the fork and reduces
slippage in the joint between the axle clamps and the axle.
6
Top Out Bumper – A rubber, coil spring, or elastomer device that absorbs the shock that occurs
when the load is taken off a suspension so that it is allowed to rebound to its limits
TPC – (Twin Piston Chamber) a patented damping system that has independent pistons for
rebound and compression. The system utilizes a mixture of air and oil in the damping leg of the
fork to enhance the damping performance.
TPC+ - A variation of TPC that has added a floating piston to the compression damper to
enhance the performance of the compression damping under the load of bigger hits.
Travel – The amount that a wheel moves between the most compressed and the most extended
states of the suspension
Viscosity – A description of how a liquid flows. Liquids with higher viscosity are thicker flow less
easily or quickly than liquids with low viscosity. This has an affect on the damping speeds of
rebound and compression.
Volume Control – A new system designed to work with SPV as a control of the compression
ramp up rate of the fork. It has a range of adjustments from linear to very progressive.
Wiper Seal – A rubber material that is used as a seal to keep dirt and water out of the outer
casting legs. It is not designed to keep air pressure or extreme oil pressure in.

Disassembly Instructions for Absolute and TPC Damping
Fig. 1
Fig. 2
Fig. 3
1. First the rebound knob will need to be removed. Screw the rebound all the way in
(clockwise), and then remove the 2mm hex screw inside the knob by turning it
counter- clockwise. Remove the knob by pulling gently away from the fork.
2. Use an 8mm hex wrench to turn the damper shaft clockwise until it can be pushed
into the casting. (see Fig. 1)
3. From the left leg dropout (Left when sitting on the bike), use a 10 or 11mm wrench to
remove the compression rod screw.
4. Remove crown/steer/inner leg assembly from the outer leg casting by pulling firmly on
the casting. The fork uses the Semi bath Lubrication system, use caution as the oil
that is in the casting will be released when the casting is removed, it is best to do this
over some type of catch pan.
5. For forks with Absolute compression damping:
a. Unscrew the 2mm Allen screw that holds the adjuster knob to the assembly
and remove the knob. There are two ball bearings sitting on top of springs
underneath the adjuster cap. Place those aside. Using a 24mm socket
unscrew the Absolute assembly from the crown. Pull the assembly out of the
fork leg. Fig 2 (Note: there will be a small amount of oil that comes out
of the inner leg, when the assembly is pulled from the crown)
6. For forks with TPC compression damping:
a. Twist the knob all the way counter-clockwise to reduce the amount of
compression damping on the system.
b. Unscrew the 2mm Allen screw that holds the adjuster knob to the damping
assembly and remove the adjuster knob. There are two ball bearings sitting
on top of springs underneath. Place those aside.
c. Unscrew the compression assembly from the crown using a 20mm socket. It
may be necessary to twist the assembly like you would be unscrewing a
screw and gently pull upward to free the assembly from the crown. Fig. 2
(Note: there will be a small amount of oil that comes out of the inner leg,
when the assembly is pulled from the crown)
7. Turn fork upside down over drainage pan to empty Damping oil from the inner leg.
Stroke the Damper shaft on the bottom of the inner leg 3-5 times to purge the leg of
oil that is caught below the Rebound piston.
8. Unscrew Damper end cap from the bottom of the right leg and then carefully pull the
damping assembly out of inner leg. See Fig. 3

Assembly of Absolute and TPC Damping System
WARNING When installing the outer Leg Casting to the Crown Steer Assy,
Compression Rod bolts and Damper Shafts must be properly tightened
prior to use. Failure to do so could result in injury or possible death.
9. Install the damping assembly into bottom of inner leg. Be sure to apply a thin layer
of Prep M grease onto piston ring that is around the piston at top of assembly.
Install the assembly and tighten end cap to specified torque value.
NOTE: Proper torque of the damper cap to 92 - 115 Kg/Cm (80 - 100inlbs) is
critical; failure to tighten properly will result in system failure!
10. Turn Crown/steer/leg assembly right side up, so that the crown of the assembly is
facing you. Extend the damping assembly all the way out and then pour damping oil
(P/N: 85-0023) into the right inner leg. Fill leg about ¼ full. Take a rag and cover the
top of the right inner leg and then stroke the damping assembly up and down about
5 times. This will insure that oil gets below the piston and not create an air space.
11. Extend the damping assembly all the way out and then fill the inner leg to the
specified oil level in the Oil Heights Chart at the end of the manual.
WARNING All top caps for Damper and Spring systems must be properly
tightened prior to use. Failure to do so could result in injury or possible death.
12. For forks with Absolute and TPC compression damping:
a. Put a little bit of Prep M grease (Ref Answer Products PN 85-0031) on the
glide ring or o-ring found on the lower piston of the assembly.
b. Push the assembly into the fork leg and tighten down the top cap.
c. Once the cap is tightened insert the springs into opposite holes in the top
cap and then place the ball bearings on top of the springs (place a little dab
of grease on spring to hold ball bearing in place).
d. Place the adjuster knob onto the hex shaped aluminum shaft and seat it
onto the top cap and ball bearing.
e. Insert 2mm fixing screw and tighten to secure the knob. Compress the fork
several times to circulate the oil through the system.
15. Turn completed crown/steer/leg assembly upside down, so that the compression
rod and damper shaft are facing you. You will see a bottom out bumper on the
damper shaft; slide this bumper down towards the end cap that is threaded into the
inner leg. This will help in keeping the shaft extended as you install the outer
casting.
16. Replace the o-ring at the end of the rebound shaft, if not you will risk having a leak
in that area.
17. Extend the rebound damper out from end cap as far as it will go and then slide
bottom out bumper towards the end cap as far as it will go. The bumper will help to
hold the damper shaft in place as you are inserting the inner legs into the casting.
18. Press inner legs into casting about half way and then inject Semi Bath oil (5/40wt.
synthetic oil, P/N: 85-0022) into outer casting, holding fork at 45 degree angle to the
ground with bottom of fork in the air (drop outs up). Inject 16cc’s of oil into each
outer leg. It is recommended to use a syringe to inject oil.
19. Press inner leg assembly into outer leg casting until damper shaft contacts casting.
Adjuster hex shaft should protrude slightly from casting.
20. Use an 8mm hex wrench to turn the damper shaft counterclockwise, threading it
into the casting. Tighten to 3.4-4.5 Nm (30-40 in-lb)..
21. Install rebound adjuster knob if applicable. Knob should turn uninhibited until the
indicator is stopped by the casting

away from your face, as there may also be a discharge of a mixture of air and oil
when you depress the Schrader valve core (this is similar to the discharge when you
depress the valve core on any of the Manitou Air or SPV forks).
2. On the bottom of the left leg (leg that has the Disk Brakes mounts on it), there is a
Schrader valve protruding from it. Unscrew the valve cap and follow either of these
two methods for releasing all of the air from the system. (See Fig. 1)
3. Depress the valve core and let all of the air out. Now depress the IT lever on the
bike’s handlebar and release it. Once again, depress valve core in the Schrader valve
to release any air in the leg. Do this a couple of times, until all of the air is released.
If you have a helper, have them hold the IT lever on the handlebar down as you
depress the valve core. This will let all of the air out at one time.
4. Now that all of the air is released, Remove the casting:
a. From the left leg dropout (Left when sitting on the bike), use a 12mm wrench to
remove the compression rod nut.
b. From the right leg dropout, remove the rebound knob. Screw the rebound all the
way in (clockwise), remove the 2mm hex screw inside the knob by turning it
counter clockwise. Remove the knob by pulling gently away from the fork.
c. Use a 8mm hex wrench to turn the damper clockwise until it can be pushed into
the casting. (see Fig. 2)
d. Remove crown/steer/inner leg assembly from the outer leg casting by pulling
firmly on the casting. The fork uses a Semi bath Lubrication system, use caution
as the oil that is in the casting will be released when the casting is removed, it is
best to do this over some type of catch pan.
5. Use an Adjustable Wrench and unscrew the black end cap that is threaded into the
bottom of the left inner leg. (See Fig. 3)
6. Pull the lower IT assembly from the inner leg. There may be a small amount of oil that
comes out of the inner leg as you remove the lower IT assembly. This is the
lubricating oil used to allow the air piston on the lower shaft assembly to move freely.
7. Now it is time to remove the IT upper assembly. Release the IT control wire from the
control lever (if attached) by unscrewing the fixing screw on the lever that holds the
cable tight. Use a 2mm Allen Wrench to unscrew this screw and then pull the cable
out of the lever.
8. To remove the upper IT assembly, use a slotted 22mm 6 point socket (P/N: 83-2503),
a 22mm Open End wrench, or an adjustable wrench. Unscrew it by turning counterclockwise. Note: Be aware of the IT control Wire spinning around when
unscrewing the top cap (See Fig. 4)
9. Pull the upper assembly out of the inner leg.

Assembly Instructions
Troubleshooting Tips
** If the fork starts to lose travel from an extended position to a shorter position by itself,
the damage is most likely centered on the Quad ring around the outside of the piston.
Fig. 6
**If the fork extends from a shorter travel to a longer travel by itself, the failure can be
involving the smaller Quad ring that is located under the piston on the inside diameter of it
where the shaft of the upper assembly intersects the lower assembly and piston. The
shaft is sealed against leakage at this point to define the two different chambers. (Fig. 5)
Always check two things when you have the system apart.
**Use a straight edge and lay it next to the inner shaft that is attached to the top cap of the
upper assembly to insure that that shaft is not bowed at any point. We found that in the
assembly of these pieces, the shaft is pressed into the top cap and occasionally if it is
over-pressed, the shaft will bow. This means that, where the bow is in the travel of the
shaft, it will cause the Quad ring that it is passing through, to distort. Thus air transfers
from one chamber to the other and the fork will extend by itself. If this is the case, you will
need a new top assembly and an O-ring kit. (Refer to Figure 6)
Fig. 7
**Make sure that the valve core in the Schrader valve is tight and does not stick open or
closed. If this is faulty, replace this valve core with a new one. Any bicycle tube valve core
will work, as well as any valve cores that we currently use on any of our other products.
Note: Always replace all o-rings and seals provided in the IT O-ring kit, each time
you take the system apart, this will insure that you receive maximum performance.
Installation of the IT Control Wire
Fig. 8
Fig. 9
1. In order to change the inner control wire, start by following IT disassembly steps 1, 2, 6, 7,
& 8.
2. Once you have the upper assembly out of the fork, use the adjustable wrench and the
12mm Open End wrench to unscrew the top cap from the shaft of the assembly. Refer to
Figure 7 at the right.
3. As you unscrew the top cap, you will feel a little tension created by a spring that is under
the cap. Separate the top cap from the shaft once you have completely unthreaded the
two pieces.
4. Pull on the inner wire in order to remove the machined stopper with the cable end in it
from the shaft.
5. You can now unhook the cable from the stopper and from the cable head end, pull the
cable through the spring, the top cap, and the outer cable housing. Refer to Figure 8 at
the right.
6. Reverse the above steps to replace the cable.
Note: The inner cable can be replaced with a standard bicycle derailleur cable
It is recommended to replace the two O-rings on the stopper each time that it is
removed from the shaft, in addition to the Black Buna O-ring that is on the shaft
below the threads.
Replacement of Piston Quad Rings
1. Refer to Figure 10 for wrench placement. Hold the 12mm wrench in place on the flats that
are on the piston seat and turn the piston with the adjustable wrench in a counter
clockwise motion to unscrew the piston from the shaft.
2. Once the piston is off of the shaft, you will see a small Black Quad ring inside the top of
the shaft that you just unscrewed the piston from. Replace this Quad ring with a new one
from IT O-ring kit. Be sure that the new quad seal is seated in the shaft and rests flat
against the shelf inside of the shaft. (Refer to Figure 9)
3. Install the Air Piston back onto the shaft in the reverse of the way you removed it. Tighten
the piston to 15inlbs (1.7Nm) onto the shaft.
4. Remove the large Quad ring on the outside of the piston, Discard this Quad ring and
replace it with a new one. Be careful not to twist it in the groove that it rests in.

Assembly Instructions
Installation of the IT Air Spring and Travel Adjust Assembly
WARNING All leg caps for Damper and Spring systems must be properly tightened
prior to use. Failure to do so could result in injury or possible death.
WARNING When installing the outer Leg Casting to the Crown Steer Assy,
Compression Rod bolts and Damper Shafts must be properly tightened prior to use.
Failure to do so could result in injury or possible death.
Fig. 10
Fig. 11
1. It is recommended that when reassembling the IT system that you start by installing the
lower assembly into the bottom of the inner leg first. Be sure to apply a small amount of
Prep M grease to the Quad ring on the outside of the piston, in the hole in the piston and
onto the threads of the inner leg before inserting the assembly into leg.
2. Twist the shaft assembly as you insert piston past the threads of inner leg. Tighten end
cap to 25-35inlbs (2.8-3.9Nm). It might be necessary to use a socket and extension thru
the top of the fork leg and engage the head on the top of the piston so that you can screw
in the quad seal past the threads in the leg.
3. Put a small amount of Motorex grease on the end of the Upper Assembly shaft, and then
insert the assembly into the fork inner leg.
4.
As soon as contact is made with the hole in the top of the air piston/lower assembly, twist
the upper assembly like screwing in a screw to guide the upper assembly shaft into the
hole without damaging the Quad ring seal in the shaft of the lower assembly.
5. After reinserting the upper assembly into the fork but before screwing the top cap in, pour
about 8-10cc’s of Air Piston Oil (40wt. automotive oil maybe substituted) into the fork leg
through the top of the crown.
6. Torque the top cap to 60-80 in/lbs using the slotted 22mm socket.
7. Replace the Outer Casting if it has been removed as follows:
a. Replace the o-ring at the end of the rebound shaft, if not you will risk having a
leak in that area.
b. Extend the rebound damper out from end cap as far as it will go and then slide
bottom out bumper towards the end cap as far as it will go. The bumper will help
to hold the damper shaft in place as you are inserting the inner legs into the
casting.
c. Press inner legs into casting about half way and then inject Semi Bath oil (5/40wt.
synthetic oil, P/N: 85-0022) into outer casting, holding fork at 45 degree angle to
the ground with bottom of fork in the air (drop outs up). Inject 16cc’s of oil into
each outer leg. It is recommended to use a syringe to inject oil.
d. Press inner leg assembly into outer leg casting until damper shaft contacts
casting. Adjuster hex shaft should protrude slightly from casting.
e. Use an 8mm hex wrench to turn the damper shaft counterclockwise, threading it
into the casting. (See fig. 10) Tighten per the Schematic and Torque
Specification Table for your fork.
f. Install rebound adjuster knob if applicable.
g. Install the compression rod screw and tighten per the Black Schematic and
Torque Specification Table.
8. Feed the inner wire through the cable housing and secure one end of the of the housing
into the gold cable guide, then feed the end of the inner wire through the hole in the black
cable stop on the lever.
9. The inner wire now feeds through the hole in bottom of the lever, over the top of the lever
and through the hole in the back of the lever.
10. Pull the inner wire until there is no slack in the cable. Be sure to set a 2mm gap between
the front of the lever and the top of the cable stop to insure that you have not over
tightened the cable before you tighten the 2mm Allen bolt on the front of the lever to cinch
the inner wire. (Refer to Figure 11)
11. The last step is to cut the inner wire that is left hanging on the backside of the lever and
then installing the cable end to prevent it from fraying.
12. Pressurize the system and check for proper function. It is fastest if you have someone
depress the control lever and hold it while you pump air into the system. This way the
system equalizes immediately. If you do not have a second person to help, just add air to
the system and then periodically depress the lever to equalize the pressure.

Section 3: Outer Casting Service
Fig. 1
1. From the left leg dropout (Left when sitting on the bike), use a 10 or 11mm wrench to
remove the compression rod screw.
2. From the right leg dropout, if the fork has adjustable rebound, the knob will need to be
removed. Screw the rebound all the way in (clockwise) remove the 2mm hex screw
inside the knob by turning it counter clockwise. Remove the knob by pulling gently
away from the fork.
3. Use a 8mm hex wrench to turn the damper clockwise until it can be pushed into the
casting. (see Fig. 1)
4. Remove crown/steer/inner leg assembly from the outer leg casting by pulling firmly on
the casting. If the fork uses the Semi bath Lubrication system, use caution as the oil
that is in the casting will be released when the casting is removed, it is best to do this
over some type of catch pan.
Changing the Dust Seals
Fig. 2
1. To remove the dust seals, first remove the seal tension springs (otherwise they will
get damaged), then take a large flat-bladed screwdriver and insert the tip between the
bottom of the seal and the top of the foam wiper. (see Fig. 2)
2. Push down on the screwdriver. This will pop the seal out of the casting. Next remove
the foam oil ring. (see Fig. 3)
3. Oil the foam rings (new or after cleaning the old rings) with a small amount of semibath oil and place them in the top of the casting above the Upper Bushings. (see Fig.
4)
4. Install the dust seal into the leg, use a large socket or piece of round tubing that is
large enough in diameter to press on the outside shoulder of the seal rather than
putting pressure on the sealing lip and spring so that they are not damaged. Repeat
steps 1-4 for the opposite fork leg. (see Fig. 5)
