Interpreting Engine Numbers
 

I have a motor I just pulled from an SC and I wanted to know how to decode the engine number.
The number I have is:
930.101.103.4R
I tried searching for this but couldn't find it. Any help is greatly appreciated.

That's not the engine number. You are looking for a stamped number, such as 930/03 or 930/04. That will be the engine type number, which identifies what market it was built for and what specifications it has. There is also a serial number, which is probably pretty irrelevant for your quest. Look on the right side of the fan housing to find the numbers.

Thanks, I pulled this # off of it:
6402859
I hope this is the right one and I appreciate the help. Is there a link you can refer me to?

That's the serial number stamped vertically on the right side of the fan housing...look a bit further to the right...but on the horizontal FLAT of the engine..... 930/21, etc kinda number....
