How to Change the Torsion Springs on a Ski Doo MXZ

Your Ski Doo MXZ takes you deep into the wilderness thanks to a track drive and a robust suspension system. Maintaining these systems is important in avoiding a long walk home and possibly a night in the woods. The rear torsion springs on your Ski Doo provide the return force for the suspension. By installing firmer or lighter springs you can tailor the ride of your snowmobile to your preference.

Instructions

    • 1

      Pull down on the torsion spring ends with your hand and push away from the adjusting cams. This removes the tension from the springs.

    • 2

      Loosen the two bolts that secure the top axle to the snowmobile's chassis with a socket and ratchet. If the bolts are difficult to remove, heat the bolt head with a propane torch to loosen the thread lock.

    • 3

      Lift the rear of the MXZ off the ground with a suspension stand under the rear lift handle.

    • 4

      Remove the locking rings from the end of the top idler wheels with needle-nose pliers and pull the idler wheels off the top axle.

    • 5

      Pull the torsion springs off the top axle with your hands. Reinstall the new torsion springs, reversing the process used to remove the old ones. When installing the top axle bolts, apply a small amount of thread locker to the bolts before tightening them.
