THE PERFECT FIT
M-10 Suspension
Setting the Rear Compression Spring Preload
Dimension B
1. Using the spanner
wrenches in your tool kit,
rotate the x--over tube
assembly to achieve the
desired spring preload
setting. Be certain the
aluminum locknut and
adjuster collar are locked
against each other before
starting adjustment.
2. While adjusting, keep in
mind that spring preload
is a FINE adjustment.
COARSE adjustments
should be made using the
FRA.
NOTE: Preload is set “softest” when the preload dimension (B) is
equal to zero. Adjusting spring preload beyond this could cause dam-
age to the threads.
Adjusting the X-over Tube Length - Dimension C
1. Use the spanner wrenches located in the tool kit to unlock the upper
lock nut from the adjuster collar.
2. Turn the adjuster collar to the appropriate or desired dimension for the
rider’s weight (refer to the initial set-up reference chart located under
the hood of your snowmobile). Tighten the upper lock nut firmly
against the adjuster collar using the spanner wrenches.
NOTE: The correct setting of the X-Over tube length enables the M-10
to deliver superior performance in “bottoming” situations. This
adjustment has no effect on spring pre-load or general ride
characteristics of your M-10 rear suspension, only bottoming
resistance.
