Engine

The engine is a Caterpillar C18 ACERT turbocharged aftercooled diesel 6-cylinder 24-valve liquid-cooled with a displacement of 1106ci / 18.1L and bore/stroke of 5.71x7.2inches / 145x 183 mm. It has a Tier III emission rating and produces 585hp / 436.2kW of power at a rated RPM of 2100. The engine is started electrically with a 12-volt starter.

Transmission

The transmission is a 16-speed full power shift. Unfortunately, no further details were provided in the .

Brakes

The brakes are not hydraulic, but rather use a Caterpillar C18 ACERT turbocharged aftercooled diesel 6-cylinder 24-valve liquid-cooled engine brake. The engine brake is a compression release brake that works by restricting the flow of air out of the engine, which creates resistance and slows the vehicle down. The engine brake is activated by a switch on the dashboard. The brakes are also equipped with an anti-lock braking system (ABS) to prevent the wheels from locking up during hard braking. The ABS system uses sensors to monitor the speed of each wheel and adjusts the braking pressure accordingly.

Steering

The steering is an articulated power steering system that is controlled by a Caterpillar 18.1L 6-cylinder diesel engine. The steering system is designed to provide precise control and maneuverability, even in tight spaces. The steering wheel is adjustable for height and tilt, and the cab is equipped with air conditioning to keep the operator comfortable during long hours of operation. The fuel tank has a capacity of 390 gallons / 1476.2L.

Common Problems

Users have reported issues with the inboard planetary final drive, which can be expensive to repair or replace. Some users have also complained about the electro-hydraulic front and rear differential, which is an optional feature that can be prone to failure. Additionally, some users have reported problems with the engine brake, which can fail to engage or disengage properly.

What Users Like

Users appreciate the four-wheel drive and articulated power steering, which provide excellent control and maneuverability in a variety of conditions. The cab is also well-designed, with air conditioning and adjustable controls that make it comfortable for long hours of operation. Users also like the wide range of tire options available for this model, including 800/70R38, 650/85R38, 620/70R46, 520/85R46, 520/85R42, and 480/80R46.
