Auxiliary Code Breakdown  
The auxiliary code is the first two characters in the serial number. The first 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  
significant 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.
