Installation Notes

Use the correct pulley removal and installation tool for the engine application and pulley type to avoid damage. Check accessory pulley alignment with a straightedge or laser alignment tool if belt tracking concerns are present. The replacement pulley should be pressed on until the hub is flush with the end of the shaft for proper alignment with adjacent accessory pulleys. Inspect belt condition and tension during service, since a cracked or stretched belt can slip or fail.
