Problem

The snap rings may be distorted or missing in the 1359312, 1406816 and 1406889 Retainer Assemblies used in 5130 and 5230 Ground Engaging Tools. Due to manufacturing problems, the snap ring inside the retainer assemblies may be distorted or twisted sufficiently so that they will not be able to drop into the grooves of the mating pins and positively lock them in place. The loss of retention will allow the pins to fall out of place and result in the loss of bucket edge covers or tips. In some instances, the snap rings may have been left out of the assemblies.
