What It Helps Address

Installation Notes and Tips

Verify crank bore, bolt pattern, pulley groove count, and overall dimensions before installation. This balancer does not include hardware, installation instructions, a woodruff key, or a crank trigger/exciter plate. Confirm vehicle configuration carefully, including the 2001 Ford F-350 Super Duty application noted for use without A.C. Use the timing marks during setup and follow the vehicle service procedure for proper torque and alignment.
