Installation Notes and Tips

Verify crank bore, bolt pattern, and pulley groove count before installation. Use the included timing marks to confirm engine position during setup, and inspect the crank snout, pulley alignment, and surrounding drive components before final assembly. Because hardware is not listed as included, plan to reuse or source the required fasteners separately if needed. Confirm fitment against your specific Dodge D250, D350, W250, or W350 diesel application before installation.
