CAT 16M3 Motor
The new Cat 16M3
Motor Grader features
ments that boost fuel
add operator conveni-
ence and promote the
safety of both the operator and
those around the machine.
The 16M3 is available in configurations to meet engine
emissions standards worldwide.
It has a 16 foot (4.9 m) moldboard and an average op-
erating weight of 71,454 pounds (32 411 kg). The motor
grader is optimally sized for operations using 150 ton (136
tonne) or smaller trucks.
The 16M3 features a Cat C13 ACERT engine which pro-
vides net power ratings from 290-348 horsepower (216-
The engine is available in three configurations to sat-
isfy global emissions standards: U.S. EPA Tier 4 Final/EU
Stage IV/Japan 2014 (Tier 4 Final); Tier 3/Stage IIIA /Japan
2006 (Tier 3) equivalent; and Tier 2/Stage II/Japan 2001
(Tier 2) equivalent.
A new ECO mode, standard for Tier 2 equivalent and
Tier 4 engines, is designed to improve fuel economy by
optimizing engine speed to 1,900 rpm in working gears
when possible with no compromise in performance.
This operator-selected feature delivers fuel savings
estimated at up to 4 to 5 percent, compared with working
in comparable light- to moderate-load applications with
the system deactivated.
An additional engine control system feature provides
consistent power to the ground by continually adjusting
the engine to compensate for power losses to the cooling
Also new for the 16M3 is the “OK-to-Start” system,
which automatically checks the engine coolant, engine oil,
and hydraulic oil levels when the key is turned to the on
Drive train and
The Cat direct-drive, power-
shift transmission, with eight
forward and six reverse gears,
incorporates the Cat Advanced
Productivity Electronic Control
Strategy (APECS) system, de-
signed to smooth gear changes
and promote productivity.
The modular trans-axle
now has a standard automatic
differential lock, which ensures
unlocking for opti-
mum traction and
averting possible damage from ill-timed manual control.
The 16M3 also features nearly 15 percent greater
dynamic braking torque at the rear tandems, achieved
by enlarging both the brake disc diameter and the piston
A new manual brake wear indicator simplifies disc
wear measurement, eliminating having to remove the
brake pads to check wear.
The front frame, hitch area and rear frame have been
specifically designed to ensure long-term durability with
the added weight and power of the new model.
The centre-shift section is now a heavy-duty steel cast-
ing designed to effectively distribute stress and enhance
durability in this highly loaded area of the mainframe.
In the cab
The new full colour touch-screen display allows the opera-
tor to monitor machine performance, set parameters to
suit operating situations, and access service information
for initial troubleshooting.
The new display also shows Cat Grade Control Cross
Slope readings and DEF (diesel exhaust fluid) level.
In addition, a new keypad with lighted, one-touch but-
tons replaces most of the three-position switches used
previously, further easing the operator's job.
Advanced Control joysticks (a retrofit option) enhance
control of the Cat Grade Control Cross Slope or AccuGrade
systems and also have provision for auxiliary-hydraulic
