Rear Spring Preload
The top section of the crossover tube (the tube at the top of the rear
shock) has a threaded collar on it. The rear spring has a lock tab that
fits into the collar to allow easy spring preload adjustment. Refer to
the initial setup chart on page 43.
1. To increase preload, use
the tool kit spanner wrench
to rotate the crossover
toward the left side of the
snowmobile (clockwise
when viewed from below).
Rotate toward the right
side to decrease preload
(counter-clockwise when
viewed from below). Be
sure the aluminum locknut
and adjuster collar are
locked against each other
before starting the
adjustment.
2. While adjusting, keep in
mind that spring preload is a
fine tuning adjustment. Coarse
adjustments should be made using the FRA.
NOTE: Preload is set "softest" when the preload (dimension B in il-
lustration and setup chart) is equal to zero. Adjusting spring preload
beyond this could cause damage to the threads.
