Primary Fixed Sheave for Yamaha

This primary fixed sheave is the driven half of the primary clutch assembly on Yamaha Grizzly and Kodiak models, working with the sliding sheave and belt to transfer engine power to the driveline.

Overview

This primary fixed sheave is a direct replacement clutch component for Yamaha Grizzly 350, Grizzly 450, and Kodiak 450 ATVs.

Good To Know

Q: Can I replace just this sheave instead of the whole clutch? A: Yes, if only the fixed sheave is worn or scored, it can be replaced on its own after inspecting the sliding sheave and belt for matching wear.

Q: Does this sheave come with the belt or weights? A: No, this listing covers the fixed sheave only, so reuse or replace your existing belt, weights, and spring as needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
