I'm going to replace the vibration damper (harmonic balancer) this weekend and was wondering if it is directional or has to be aligned with a mark anywhere? When I resealed my timing cover a couple years ago I just slapped it back on and torqued to spec, but I figured I'd ask the genesius this time. It's an oem cummins, can't run anything else with the fuel boss...
