SUBJECT: SERVICE SUPPORT OF CERTAIN 320C EXCAVATORS

PROBLEM:

Caterpillar Redistribution Services Inc. (CRSI) will soon be receiving certain machines that will be distributed within the North American Commercial Division (NACD). Because the machines were configured for use inside Japan (ISJ), they will be different from the machines that are produced in Japan and configured for use outside Japan (OSJ). The differences between the OSJ version and the ISJ version may create confusion for service and support personnel.

SOLUTION:

Identification of the differences between the two machine versions will provide service and support personnel with the information necessary to efficiently perform their duties. The following tables list the differences between the versions. A cross-reference list of available support literature is also provided.
