Product Overview
Caterpillar identifies 394-3494 as a 12V 65A alternator. The original title's loader list appears to match a different 85A alternator family, so those unsupported loader applications are not carried forward.
This unit should be matched by Cat serial number, mounting and electrical connections because similar 12V alternators are available in multiple amperage ratings.
