BENEFITS & FEATURES
Engine
The IT38G II provides more power, excellent fuel economy, and reduced maintenance.


Engine

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.

Cooling System
The G Series II cooling package reduces radiator plugging and improves fuel efficiency.


Cooling System

Excellent System Access
The IT38G II provides a swing-out grill, hydraulic oil cooler and air conditioner condenser for easy cleaning. Side panels open to allow access to both sides of all cores for cleaning. A heavy duty airborne debris grill, with 4 mm perforations is available as an attachment.

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.

Environmental Features
Caterpillar cares about the environment and continues to develop innovative solutions.


Environmental Features

Low Exhaust Emissions
The Cat® 3126B ATAAC engine used in the IT38G Series II is a low emission engine designed to meet current emissions regulations. It is electronically controlled, with air-to-air aftercooling for more efficient combustion and cleaner emissions.

Reduced Sound
The electronic on-demand fan automatically regulates fan speed depending on cooling requirements. The fan draws less horsepower in cooler ambient temperatures, which reduces fuel consumption. Sound levels are also reduced when the fan slows down. There is additional insulation around the engine to reduce sound levels.

Environmental Fluids
Extended Life Coolant/Antifreeze with anti-foaming and anti-corrosion properties provide extended service intervals (up to 6000 hours) and requires less frequent fluid changes and disposals. Air conditioning refrigerant is CFC-free.

Fewer Leaks And Spills
Oil sampling valves and pressure test ports are included for easy service diagnostics, with less chance of spills. Filters are positioned vertically and located for easy access, allowing for removal without fluid spillage.

Ecology Drains
Standard for the engine, transmission, hydraulics, radiator and fuel. Activating the valve allows fluid to be drained into a container without spillage. Axle oil ecology drains are an attachment and allow quicker oil changes with reduced spillage.
