Spring Identification - BOMBARDIER 1996 Ski-doo MX Z440 Handbook

The preload on a torsional spring is controlled by the free opening angle and the installed opening
angle. If a torsional spring must be "twisted" more to be installed, then it will have more preload
(following illustration).

Spring Identification

Our springs will have one, 2 or 3 stripes of color painted on the spring. This is the color code used
for identification. Refer to the applicable chart to find a cross reference between the part number,
model application, color code, spring rate, free length and spring type. The spring type denotes
physical characteristics of the spring like the inside diameter of the ends which will determine the
type of retainer used to hold the spring. All spring types are not interchangeable.
o
NOTE : Springs that fit the front of the F-2000 Chassis will generally fit the front of the
S-2000 Chassis.
Springs that fit the center of the F-2000 Chassis will generally fit the center of the S-2000 Chassis if
the plastic snow protector is taken off the shock.
CHECK THE SPRING TYPE AND FIT OF THE SPRING RETAINER BEFORE INSTALLING DIFFERENT
