Torsion Springs/SAG Setting
The INDY 121 and Switchback 144 rear suspensions are
equipped with rear torsion springs. The spring preload can
be set by adjusting the torsion spring preload blocks.
The torsion spring preload sets the rear suspension SAG
setting. SAG is the d
ifference between the unloaded and
loaded rear bumper height when the snowmobile is sitting
on snow.
The SAG specifications are:
1. Position the snowmobile on snow.
NOTE: Positioning the snowmobile on a hard
su
rface (pavement/concrete) distributes more
weight to the rear track shock/torsion springs and
can distort the following measurements.
2. Lift the rear bumper to fully extend the rear
suspe
nsion. Using a tape measure, find (X).
3. Have the rider, in riding gear, mount the snowmobile.
Th
e rider should drop down hard on the seat and
bounce the suspension several times to collapse the
suspension.
4. Again, measure the distance between the rear
bu
mper and ground (Y).
5. Subtract measurement Y from X (X-Y=SAG).
6. Set both torsion spring adjuster blocks to LOW,
MED
IUM, or HIGH to achieve the specified SAG
measurement.
NOTE: Optional torsion springs
are available to fine
tune SAG setting. See individual model
specifications in Chapter 1.
