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.
