2013 Branson 3520R Engine Serial Number

[darrenford77]

I am trying to locate the engine serial number since this is a cummins engine. I do find on the Block a model A170N2-R with number TN7T00031. The emissions control label shows model A1700N1 but the S/N is blank. Anyone know how to find the ESN?

From the service manual:
"The engine number is stamped on the cylinder block and is specified on the decal which is attached to the cylinder block on the left side of the engine. Also, the decal indicating the engine model and standards is attached on the top of the engine cylinder head cover".
