The power rating of the engine indicated in this document is the
net power output tested on a production engine for the engine
model and measured in accordance with SAE J1349 at 3,600
rpm (Net Power) and at 2,500 rpm (Max. Net Torque). Mass
production engines may vary from this value.
Actual power output for the engine installed in the final machine
will vary depending on numerous factors, including the
operating speed of the engine in application, environmental
conditions, maintenance, and other variables.

The bar graph is intended to provide you, our customer, the ability
to compare the emissions performance of available engines. The
lower the Air Index, the less pollution.
The durability description is intended to provide you with
information relating to the engine’s emission durability period.
The descriptive term indicates the useful life period for the engine’s
emission control system. See your
