What It Helps Address

• Crankshaft vibration from a deteriorated balancer
• Belt tracking issues related to pulley wear or misalignment
• Noise from a damaged or separated outer ring
• Accessory drive concerns on the serpentine system
• Replacement needs for a worn harmonic balancer on Lincoln LS and Ford Thunderbird models

Installation Notes and Tips

Verify crank bore, overall diameter, width, and pulley groove count before installation. Confirm that the vehicle uses the correct serpentine belt layout and that the crankshaft snout and mating surfaces are clean and free of damage. Because hardware, instructions, timing marks, and a Woodruff key are not included, reuse or source the required installation components separately as specified by the vehicle service procedure. Dayco PB1783N should be installed according to factory repair information for the exact application.
