How do you adjust belt on 1991 polaris snowmobile?

To adjust the belt on a 1991 Polaris snowmobile, first, ensure the engine is off and the snowmobile is on a flat surface. Remove the driven clutch cover to access the clutch assembly, then check the belt for wear. To adjust the tension, locate the adjustment bolts on the driven clutch and turn them to increase or decrease the belt tension as needed. Reassemble the cover and test the snowmobile to ensure proper belt alignment and performance.
