ENGINE SPECIFICATIONS
*1: The power rating of the engine indicated in this docu-
ment 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, mainte-
nance, and other variables.
