Review on 🔧 National Oil Seals 710162: High-Quality Crankshaft Seal for Reliable Engine Performance by James Richardson

You will need a filler remover or a 1 gallon can opener (Home Depot) to remove the old one. Get Loaner Harmonic Balancer Remover and Separate Harmonic Balancer Installer. For installation you need a "large" outlet or pipe. Apply moly grease to the crankshaft to wear it out. Use a puller to remove the harmonic balancer. Remove the old gasket. Delete everything. Use the Harmonic Balancer Installer to press in the gasket. Then use the installer to push the pulley down. Don't forget to tighten the nut!
