It's not a balancer as commonly referred to. But a harmonic dampener. It's used to reduce the harmonic that occur at certain RPM ranges in the crankshaft of internal combustion engines. That's why the outer steel mas is mounted on rubber. Run without one. The crank will break. ( GENERALLY ) The heavier the crank. The larger the damping mas. Bob Dunahugh

Subject: Did you know your timing mark can MOVE on Olds engines? I didn't.
When I went to set the timing to the proper 8 degrees of advance. It ran terrible. Called Ken Henderson. He said that the outer part of my harmonic dampener had rotated. I DID NOT know that the Olds unit could do that. I was aware of other engine. So if at some time your timing was set to a moved mark. It could be affecting the timing. Thus reducing mileage. I'm thinking that I may have set my timing retarded the last time due to this. There are indexing marks that GM did when new. New one is $42. Bob Dunahugh 78 Royale
