Installation Notes and Tips

Verify the pulley diameter, groove count, bearing bore, and mounting style against the original part before installation. Confirm the vehicle’s belt routing and accessory drive layout, especially on Mazda Miata, Mazda 323, and Mazda Protege applications with A/C or serpentine belt configurations. Inspect the belt, tensioner, and adjacent pulleys for wear so the new pulley is installed into a clean, aligned drive system.
