Auxiliary Code Breakdown

The auxiliary code is the rst two characters in the serial number. The rst character

indicates the year. Years progress or regress in alphabetical order. The series runs from

"A" through "V" and the letters "I" and "O" are skipped. The second character indicates

signicant part changes within a year. Base is "0" and this number advances for each

change. In cases where there is a letter in parentheses, this designates the month. This

is the last character in the serial number. The series runs from "(A)" through "(M)" and the

letter "(I)" is skipped. This designation is only included when identifying a parts change

within an auxiliary code.

Note About Ordering Parts

Most assemblies cannot be ordered as complete units; parts in the assemblies generally

must be ordered separately.
