Installation Notes and Tips

Verify crank bore, pulley groove count, and timing mark orientation before installation. Hardware, installation instructions, and woodruff key are not included. Use the vehicle service procedure and torque specifications for the specific engine application, and inspect the crank snout and belt drive components before fitting the new balancer.
