  How to read this chart
  1. Locate the correct manufacturer's chart
  2. Choose the specific engine application listed down the left side of the chart
  3. Determine if the damper needs to be internally or externally balanced ( external balance dampers are constructed of steel only). Black bars that extend horizontally across the entire chart designate these sections
  4. Determine if you need steel or aluminum shells. Labels for this information are listed across the top of the chart in columns 2 and 3.
  5. Once you have determined the shell material, you need to find the outside diameter (OD) of the desired steel or aluminum shell. Then choose between 2 or 3 rings and the desired weight of the damper.
  6. From the far right section of the chart, select either a steel or aluminum hub for your desired engine application. To determine the correct damper assembly part number that intersects is the correct damper assembly.
  7. Assembly part numbers that are color coded correspond to the pulley mount bolt pattern listed near the top of the charts.
