How to read
this chart
Locate the correct manufacturer's chart
Choose the specific engine application listed
down the left side of the chart
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
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.
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.
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.
Assembly part numbers that are color coded
correspond to the pulley mount bolt pattern listed near the top
of the charts.
