Installation Notes

Use installation tool 91024-1 for removal and installation. Verify the pulley style, groove count, bore diameter, and OE comparison rating before installation. Because this is a one-way clutch decoupler pulley, it is not interchangeable with standard overrunning alternator pulleys.

Quality Assurance

Gates DriveAlign components are engineered for accessory drive service where vibration isolation and alternator overrunning control are required. The OE Exact rating supports a direct replacement approach for the listed Hyundai and Kia applications.
