Ryde Fx Mono-Tube Shock Assembly - Polaris 340 LX 2007 Service Manual

Steering and Suspension Systems
excessive wear. O-rings for nicks, cuts, or cracks. Cap
and rod seals for nicks, cuts or cracks. Valve discs for
kinks or waves. Compression bumpers (ski shocks
only) for chipping, cracking or missing. Should any of
these items be
recommended.

RYDE FX MONO-TUBE SHOCK ASSEMBLY

1. Place the piston rod upper mount into the vise.
Reassemble damper rod assembly in the reverse
order of disassembly. Special attention should be paid
the order of the Rebound and Compression disc
(shim) stacks, ensuring that they are in the same order
prior to disassembly. Tighten the lock nut to 15-20 ft-
lb. of torque. DO NOT OVER-TORQUE. If excessive
torque is applied, damage to the piston and valves will
occur.
2. Secure the shock body by its lower mount in vise. The
use of soft jaws is recommend to prevent damage or
marks to the shock. It is important that the gas shock
be retained in the vice by the lower mount. Any other
method of securing the shock body during these
procedures may deform the shock body cylinder.
NOTE: The next points on IFP are not applicable for
emulsion shocks. Proceed to assembly of the
pressure valve.
3. Thread the positioning head onto the I.F.P locator tool
and adjust the top of the value indicator to the
appropriate measurement. Depending on which
shock absorber is being worked on, adjust the piston
location tool to the specified depth indicated in the
shock specification chart.
4. Apply a thin film of oil onto the floating wear band and
O-ring and install the floating piston into the top of the
shock body, positioning it below the counter-bore.
5. Using the tool as a handle, push the floating piston
down into the shock body, being careful not to
damage I.F.P wear band and O-ring, until the value
indicator knob comes in contact with the shock body.
The piston should now be located correctly.
6. Screw the pressure valve assembly into the valve port
by hand with a slotted head screwdriver; and tighten
to 100-110 in.lb of torque.
7. Fill the shock body with shock oil. Internal Floating
Piston Shocks: Fill the shock body with shock oil to the
bottom of the thread within the cylinder. Emulsion
Shocks: Fill shock body with 110cc's of oil. This will
allow for the required air space to properly gas charge
the shock with nitrogen gas.
NOTE: After filling the shock body with oil, allow a
couple of minutes for all air bubbles to rise to the top.

8. With the cylinder head assembly pushed down
against the piston, carefully, insert the piston rod and
assembly into the cylinder; Slightly oscillating the
piston rod to allow piston to enter shock body bore. A
is light coating of oil on the piston wear band will ease
installation.
9. Slowly push the piston rod and assembly into shock
body until the cylinder head assembly bottoms on the
cylinder counterbore. Slight up and down movement
may be required to allow all air to pass through piston
assembly.
10. During installation, some shock oil will overflow. Wrap
a shop cloth around shock body to catch possible oil
overflow. Fast installation of the piston rod and
assembly may displace the floating piston from its
original position. This must not occur if the damper is
expected to perform as designed.
11. Using an open face spanner wrench tighten cylinder
head securely into the shock cylinder.
12. Pressurize the shock, through the pressure valve,
with nitrogen gas to the specified pressure.
13. If using RydeFX inflation tool Refer to Procedures for
use of replaceable inflation needle instruction manual
found in the RydeFX inflation tool case.
14. After being compressed, the piston rod should fully
extend from the shock body once the shock has been
pressurized.
15. Install the small button head screw in the pressure
valve assembly and tighten securely.
16. Reinstall sleeve and bushings in lower shock mount.
