How to adjust your Ski‑Doo drive belt
If you cannot get your new drive belt set to the correct height, you can use the same tools in your left side panel to adjust it.
1- With your sled parked and tether removed, open the left side panel (remove belt guard if necessary) to expose the pulleys.
2- Loosen the clamping bolt on the adjuster hub with the Torx end of the pulley expander. Note, you don’t need to completely remove it.
3- With your suspension wrench, turn the adjuster hub a quarter turn at a time and rotate the driven pulley by hand. Turning the adjuster hub counterclockwise lowers the drive belt, and turning it clockwise raises it. Repeat until your drive belt is properly set.
4- Once you’ve found the right belt position, firmly tighten the clamping bolt. If possible, use a torque wrench and torque the clamping bolt to 5.5 ± 0.5 Nm (49 ± 4 lbf-in).
