Welcome to JA!
Can i get the engine serial numbers off both motors please
Customer: replied 5 years ago.

i don't know where to look for the serial numbers on the engines.Cry i had a look but could not find it.


But as i said, the engine models is called: D179 for the mcormick international 523 (3 cyl)and D206 for the mcormick international 624 (4 cyl) the make of year is between 1965 - 1972.

you see, i don't want to go and order exspensive work shop manuals just for this info. The manuals also just name them as a D179 and D206 International Havester engines.


i hope this info could help you.

Yes this can help
Let me do some checking to see if there were any big changes on specs by serial numbers.
I do have axes to a bunch of shop manuals but go by the engine serial numbers.
Let me do some cross referencing
Im sure there is no real difference but want to make sure i have the correct information for you.
