GENERAL INFORMATION
BRIGGS & STRATTON DAIHATSU NUMERICAL NUMBER SYSTEM
All Briggs & Stratton Daihatsu engines have a unique numerical designation system. Each engine is identified by a
Model, Type and Code/Serial number. Example: Model Type Code/Serial
432447 0125 01 020521145
This chart explains the numerical model designation system. It is possible to determine most of the important mechani-
cal features of the engine by merely knowing the model number. Here is how it works.

The type number identifies certain unique features such as the crankshaft or governor spring used on an engine.
The code/serial number identifies the assembly date of the engine and serial number. In some instances it is neces-
sary to know the code/serial number as well as the model and type number when performing adjustments, repairs or
ordering replacement parts for an engine. Here is how it works.
Example: 990521150
A. The first two digits, 02, indicate the calendar
year, 2002.
B. The second two digits, 05, indicate the calen-
dar month, May.
C. The third two digits, 21, indicate the calendar
month day.
D. The last three digits, 145, indicate the serial
number.
