How does Honda number parts? Its all in the numbers

 

All parts on a Honda have a unique part number. Honda divides parts into two broad categories, General Parts and Standard Parts. General parts are those unique to Honda, such as valves, pistons, gas tank etc. Standard parts are parts that follow universal standards, such as nuts, bolts and such.


General Parts


General parts have a part number divided into 3 sections, for example 19231-500-030 water pump impellor for s600.


●The first string of digits (19231-XXX-XXX) indicates the Honda function and component number for this part. The first two digits 19 are the function number refering to the function (subassembly) where the part is used.  The next three number 231 is the component number, the unique part that provides the function.


●The second string of digits (XXXXX-500-XXX) is the product code, also known as Parts Classification Number (PCN) in Hondaspeak. This is the number that indicates the product (car or motorcycle) where this particular part was first used. 500 indicates the Honda s600.  The product code is probably the most interesting portion of the part number when trying to determine interchangeability of Honda parts between various models.  

The Parts Classification Number - commonly referred to as the PCN - should be understood in the proper context. When Honda makes a new model of vehicle, Honda will assign a PCN to each part on the bike that is also new.


●The third string of digits (XXXXX-XXX-000) is the Modification Number.The first two digits is used to indicate various improvements for the same part.  The last digit is subcontractor designation.

 


GENERAL PARTS:

XX XXX - XXX - XX X  
Position 1-2 = Function Number
XX XXX - XXX - XX X  
  Position 3-5 = Component Number
XX XXX - XXX - XX X  
      Parts Classification Number
XX XXX - XXX - XX X  
          Modification Designation
XX XXX - XXX - XX X  
            Subcontractor Designation
XX XXX - XXX - XX X  
             Parts Book Number  

 



Standard Parts numbers used for fasteners, washers and seals


Standard Parts have a part number divided into 2 sections, such as 93500-06040 (6mm x 40mm pan screw)


●The first string of digits indicates the function/type of the standard part, for example all pan screws are 93500-XXXXX.

●The second digit indicates dimensions for the part. 

●Standard parts occasionally have a third string of digits indicating the ISO standard designation and chemical surface treatment.


STANDARD PARTS INCLUDING NUTS & BOLTS:

XX XXX - XXXXX      
Position 1-2 = Function Number
XX XXX - XXXXX      
  Position 3-5 = Type Number
XX XXX - XXXXX      
      Dimensions
