The IT38G II provides more power, excellent fuel economy, and reduced maintenance.


Powerful Performance
The 3126B ATAAC engine delivers net power of 119 kW (160 hp), and meets EPA Tier 2 emissions standards. Its advanced fuel system keeps fuel at low pressure in the lines until it is injected into the cylinder. Fuel pressure is created hydraulically in response to a signal from the ADEM™ III Electronic Control Module.

Electronic Control Module
The ADEM III fuel system is a proprietary electronic control module that provides improved engine response and fuel efficiency, plus advanced diagnostics and reduced emissions. Altitude capability up to 3050 meters (10,000 feet) is available without derating. ADEM III allows full electronic integration of the engine and transmission for maximum power train efficiency.

Turbocharged, ATAAC
Turbocharging packs dense air into the cylinders for more complete combustion and lower emissions. Air-to-air aftercooling (ATAAC) provides a separate cooling system for intake manifold air. The ATAAC system reduces smoke and emissions by providing cooler inlet air for more efficient combustion.

Constant Net Horsepower
The IT38G II electronic engine is integrated with an on-demand cooling fan. The engine compensates for varying fan loads and provides constant net horsepower, regardless of operating conditions. A consistent level of “working” horsepower is provided and fuel consumption is reduced.

Oil Change Intervals
The engine oil change interval of 500 hours (with CH-4 oil), reduces costs and downtime.

Power Train
Advanced Caterpillar® power train is reliable and fuel efficient.

Power Train

Electronic Power Shift Transmission
The electronic power shift transmission with automatic shift capability is a countershaft design built by Caterpillar. It is electronically controlled and allows full power shifts and directional changes. Fully modulated gear shifts contribute to operator comfort and increase component life.

Electronic Clutch Pressure Control (ECPC)
Senses input from both the transmission and the operator controls in the cab to modulate each individual clutch through a proportional electro-hydraulic valve. This results in smoother gear changes and improved shift quality. Energy is modulated into the clutches, resulting in longer clutch life.

Integrated Braking System (IBS)
The Caterpillar exclusive Integrated Braking System integrates downshifting and transmission neutralization into the left brake pedal. IBS provides smooth, optimized transmission neutralizer performance with a greater range of adjustability. IBS also lowers owning and operating costs by reducing axle oil temperatures, which can extend service brake life.

Easy Service
Daily transmission oil level check is done from the ground through a well-protected sight gauge. An oil sampling valve allows quick, clean access to the transmission for S•O•SSM oil analysis.

Variable Shift Control (VSC)
Variable Shift Control allows the operator to select one of three different shift patterns based on the application and operating preferences. VSC reduces fuel consumption in many applications. In all modes, full machine power remains available for loading.

Limited Slip Differentials
Front and Rear Limited Slip Differentials are available as attachments. The differential clutch slows the slipping wheel and transfers torque to the slower turning wheel.

Reverse Flow
Air enters through the rear grill and exits out the top opening and side hood doors. Rear air flow picks up less debris from the ground, reducing plugging.

On-Demand Fan
Electronically controlled, variable speed on-demand fan adjusts to meet the varying cooling requirements of the machine. Fan speed is determined by oil, coolant and inlet manifold temperatures. In cooler operating conditions, average fan speed is reduced, resulting in less fuel consumption, lower noise levels and less radiator plugging.

Unit Core Radiator
The unit core radiator with square wave-shaped fins and lower fin density (6 fins per inch) allows debris to pass through easily.
