Problem

In certain applications, high reverse loads on bucket tips may cause pin
bending or breakage on some 235B/C Excavators and 988B Loaders.
Additionally, misalignment of the pin and retainer at installation may cause
retainer distortion which allows the pin to walk out of location and result
in its breakage. Eventual loss of the tip from the bucket adapter mayresult.

Affected Product

NOTE: Changing adapters is to be considered only after verification
that tip loss is a repetitive problem and cannot be resolved with
the use of an alternative pin or retainer correctly installed.
Problems caused by worn out adapters are excluded
from this Program. Worn out adapters can be determined by
examining the tip pocket. There will be impact marks from the
adapter nose front face and, in extreme cases, cracks in the top
or bottom walls of the pocket. Your claims comments must justify
adapter replacement.
