 IMPORTANT NOTE: The following information is 

designed for use as an aid in analyzing chain failures.

   Chain  Analysis

 WHY FAILURE OCCURS?

There are many different reasons a chain can fail 

in a piece of equipment. Some reasons may be 

related to the chain itself, but many reasons may 

be related to other components of the system. 

A failure of (1) interacting component such as a 

 sprocket, attachment, or a variety of others can 

cause severe damage to the chain. Such chain 

damage becomes a symptom of another problem 

and should not be considered a problem of itself. 

This Chain Analysis manual section is designed 

to help analyze failures so that the real problems 

may be corrected on a timely basis.

The next 3 pages show examples of 

typical chain failures and what must 

be done to correct each failure.
