Overload Spring
The overload spring is located inside the main rear spring. Contact is
made with this spring only when the crossover tube comes in contact
with it toward the end of the travel, which reduces bottoming of the
rear suspension. The correct setting of the crossover tube length
enables the M-10 suspension to deliver superior performance in
“bottoming” situations. This adjustment has no effect on spring
pre-load or general ride characteristics of the M-10 rear suspension, it
affects only bottoming resistance. To adjust the crossover tube length
(dimension C in illustration and set-up chart):
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 and on page 49). Using the
spanner wrenches, tighten the upper lock nut firmly against the
adjuster collar.
Optional Springs
Optional springs have been designed to allow adaptation of the M-10
suspension to your specific needs. The 140 lbs./in. optional front arm
spring would be used when very light load conditions exist, such as
operation on very smooth trails, in deep powder or by very light riders.
The 300 lbs./in. rear arm spring option would be used when high load
conditions exist, such as operation by heavy riders on rough trails or
very aggressive riding. The available springs for M-10 suspension are
listed below.
