SAFETY - PRODUCT IMPROVEMENT PROGRAM FOR ULTRASONIC INSPECTION OF STABILIZER CYLINDER RODS
MODELS INVOLVED - CERTAIN M300C AND M300D SERIES WHEELED EXCAVATORS
Dear Caterpillar Product Owner:
Immediately stop your machines from operation, or do not use the stabilizers under any circumstances and have them securely locked in the upward position by the lock pin including the lock spring. Please also refer to the OMM.
The stabilizer cylinder needs to be ultrasonically inspected and potentially replaced on the products listed below. There might be cracks in the friction weld of the stabilizer cylinder rod which may cause the fracture of the cylinder rod. This may result in sudden drawback of the stabilizer foot with subsequent tilting of the machine, when the machine is in a stabilized position. If the stabilizer is in an upward position the stabilizer may drop suddenly down. Both events may result in personal injury or death. You will not be charged for the service performed.
Contact your local Caterpillar dealer immediately to schedule this service. The dealer will advise you of the time required to complete this service.
Please refer the dealer to their Service Letter dated 15Nov2006 when scheduling this service.
We regret the inconvenience this may cause you, but urge you to have this service performed for your added safety and satisfaction.

Rework Procedure
General:
The ultrasonic weld inspection needs to be performed according DIN EN 1714 ? ULTRASONIC TESTING OF WELDED JOINTS ? including its normative references.
The ultrasonic personnel needs to be qualified and trained according DIN EN 473, Grade 2, with scope for welded joints.
If DIN EN 1714 and 473 is not available or valid in your country, ultrasonic checks need to be performed and personnel qualified by your countries corresponding Standard.
Since this is a very sophisticated task to perform we strongly recommend using qualified ultrasonic personnel. We recommend the use of the company Vohtec for dealers that are located in close proximity (please see contact details below). Vohtec has special experience with this cylinder rod failure.
