Cat® C9 ACERT Engine
Delivers, at a rated speed of 2,100 rpm, flywheel power of 173 kW (232 hp) and meets the U.S. Environmental Protection Agency Tier 3 emissions regulations and Stage IIIA EU Emissions Directive 97/68/EC. With high horsepower and low displacement, this innovative engine provides excellent fuel economy and durability which can significantly reduce operating costs.
Torque Rise
Is increased as a result of the electronically controlled, computer actuated unit fuel system that provides high injection pressure and more precisely controlled fuel delivery as the engine lugs back from rated speed.
ADEM™ IV Fuel System
Is a Caterpillar® electronic control module which provides improved engine response, performance, fuel efficiency, troubleshooting diagnostics and reduced emissions. It allows integration with the electronic transmission control for maximum power train efficiency.
Turbocharger
Packs more dense air into the cylinders for more complete combustion and lower emissions, improving performance and engine efficiency. These benefits are especially useful at high altitudes.
Air-to-Air Aftercooler
Reduces smoke and emissions by providing cooler inlet air for more efficient combustion. This also extends the life of the piston rings and bore.
Dual Cooling Jets
In the block spray oil on the piston skirt and cylinder bores keep ring temperatures low for long ring and liner life with excellent oil control.
Pistons
Are two piece articulated with forged steel crowns for excellent strength and aluminum skirts for reduced weight. Pistons are oil cooled for increased heat dissipation and longer life.
Valves
Four per cylinder allow for good airflow, enhancing fuel efficiency and heat rejection. Valves and unit injection system are camshaft-actuated for precise timing.
Crankshaft
Is a steel-forged, carburized and induction-hardened for long-term durability. It is dynamically balanced for smooth operation. The crankshaft is completely regrindable, and the connecting rods can be removed through the tops of the cylinders for easy servicing.
Cat Engine Oil
Is formulated to optimize engine life and performance and is strongly recommended for use in Cat diesel engines. Engine oil change interval is 500 hours.
Cat Planetary Powershift Transmission
Features heavy-duty components to handle tough jobs. The 345.4 mm (13.6 in) planet drives operate in all gears, forward and reverse.
Heavy-Duty Axles and Brakes
Are designed to last in all kinds of operating conditions. Two front axles disc brakes provide improved braking capability and better heat dissipation. Planetary final drives use free-floating, bronze sleeve bearings in the planet gears. • Oil disc brakes are adjustment-free and fully enclosed to lock out contaminants.
Front Axle
Is rigidly mounted to the frame to support the weight of the compactor, internal torque loads and external loads applied during compacting and dozing operations.
Rear Axle
Includes a trunnion, two trunnion supports and associated bearings, allowing it to oscillate plus or minus 12 degrees.
Four Piece Axle
Contains two axle shaft housings - the center housing and the intermediate housing. Features and benefits of this design include: • Inboard brakes on the front axle only are positioned immediately adjacent to the differential and operate on the low torque side of the final drive, requiring less braking to stop the machine.
