4. With Driven Clutch Compressor (p/n 0644-444),
compress the roller assembly enough to allow the
snap ring to be properly secured to the shaft.
CM090
NOTE: While compressing the roller assembly, it
may be necessary to work the spider assembly
back and forth to properly mate the splines.
5. Place the cam with the desired angle into position;
then secure the cam to the movable sheave with
the four torx head cap screws. Tighten to 6 ft-lb.
Installing
1. Slide the alignment washers onto the end of the
driven shaft.
2. Place the stub shaft into the driven clutch. Place
the driven clutch on the shaft.
NOTE: A small amount of Loctite Anti-Seize
Thread Compound (p/n 0678-146) applied to the
driven shaft will aid in future driven clutch
removal.
3. Secure the driven clutch by installing washers, and
cap screw. Tighten the cap screw to 2.6-3.3 kg-m
(19-24 ft-lb).
NOTE: Make sure the keyways match when
installing the driven clutch. Arrange washers to
allow the least amount of “float” on the driven
shaft. A maximum of 1-2 mm (0.040-0.080 in.) of
float is acceptable.
Ski Shock Absorber Springs
The shock absorber springs have been matched to the
shock valving and rear suspension. These springs are
the result of hours of testing and comparison riding
trying many different combinations of springs and
shocks. If there is a need to make changes, there are
several spring and shock sizes to choose from. While
making these changes, keep the following points in
mind.
Heavier/Lighter Springs
1. Using heavier or lighter springs will affect the
shock function. Changes in compression or
rebound damping may be necessary to attain
desired performance.
2. With heavier springs, the front end will become
more aggressive in the corners as more weight will
be transferred to the skis when decelerating. Also,
more weight is transferred to the rear on accelera-
tion and can cause the rear shocks and spring to
bottom out.
3. With lighter springs, the front end will generally
“ride in” more. This could aid in cornering, but
may cause the chassis to “roll.” Lighter springs
generally create more pitch change from front to
back. This can also aid with traction.
Spring Tension Too Soft
1. Front end bottoms out; hard on front end parts.
2. Less aggressive steering in corners on decelera-
tion, and less weight is transferred to the skis
because of softer springs.
3. Less weight gets transferred to rear of the machine
upon acceleration.
NOTE: When softening the ski springs, also
soften the rear to match entire suspension.
Servicing Float X Evol Shock
Absorbers
Disassembling Shock Absorber
NOTE: Some illustrations and photographs used
in the following sub-sections are used for clarity
purposes and are not designed to depict actual
conditions.
1. Rotate both adjuster screws counterclockwise to
the full-open position.
2. Securely clamp the EVOL chamber eyelet (bot-
tom) of the shock in a soft-jawed vise; then
remove the green valve caps and set them aside.
CAUTION
If the ski shock spring is adjusted too loose, the
spring retainer may fall out. If the spring is adjusted
beyond specification, the spring will coil bind and
spring adjuster damage will occur.
! WARNING
Before starting, read through all of these instructions
first to become familiar with the procedure. Make
sure the work area is clean and all of the necessary
tools are available. These shocks contain high pres-
sure nitrogen gas. Always use proper safety equip-
ment such as latex gloves and safety glasses when
working on shock absorbers.
