PROBLEM

Show/hide table

This inspection is required to ensure the retaining rings are properly installed on the extend chain clevis attachment pins. If the retaining rings are not present, the pins may disengage and lead to a separation of the extend chains from the clevis that could result in an uncontrolled retraction of the boom.

This bulletin requires inspection of the retaining rings on the extend chain attachment pins between the clevis and chain and replacement of the retaining rings, if necessary.

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 45% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.

ACTION REQUIRED

Show/hide table

Inspect the extend chain attachment pins located toward the front of the base boom (Image1), for the presence of four external retaining rings highlighted in Image2. If any of the external retaining rings are improperly installed or missing, they must be replaced with new retaining rings.

NOTE: To prevent damage to the new retaining rings during installation, ensure a tool specifically intended to install a 6mm retaining ring (E-clip) is used; similar to a Rotor Clip A-150 or Zoro A-606 tool.

MODELS INVOLVED - TL943D

Dear Cat Product Owner:

The retaining rings on the extend chain clevis need to be inspected on the products listed below.

This inspection is required to ensure the retaining rings are properly installed on the extend chain clevis attachment pins. If the retaining rings are not present, the pins may disengage and lead to a separation of the extend chains from the clevis that could result in an uncontrolled retraction of the boom.

Failure to do so may, in conjunction with other factors or circumstances, result in a risk of personal injury or death. You will not be charged for the service performed.

Contact your local Cat dealer immediately to schedule this service. The dealer will advise you of the time required to complete this service.

If you are no longer the owner of this product(s), please contact your local Cat dealer so that our records can be updated.

You may now search for open Safety Service Letters by entering your product serial number(s). Visit the CAT.COM/SAFETY website and click on SUPPORT, then SAFETY SERVICES for more information. Please refer the dealer to their Service Letter dated 28Oct2016 when scheduling this service.

We regret the inconvenience this may cause you, and urge you to have this service performed for your safety and satisfaction.
