The Caterpillar® 938H Wheel Loader and IT38H with integrated toolcarrier linkage feature the Cat® C6.6 engine with ACERT® Technology for responsive power and low emissions. The new engine, differential lock system, load sensing hydraulics and increased lift and tilt forces deliver high performance in digging and material handling applications while limiting engine emissions to meet U.S. EPA Tier 3 off-highway emissions regulations and worldwide emissions standards.

• The Cat Fusion™ Wheel Loader Coupler System. The coupler design pulls the coupler and work tool closer to the wheel loader for nearly full machine performance with the expanded versatility and flexibility of a coupler.
• An in-cab messenger display provides real time machine performance, engine and diagnostic data to help maximize productivity and component life.
• Hydraulic and electrical service centers group service points and offer easy access from ground level to limit service downtime.
• Cat Product Link - provides two-way information flow between the machine and Caterpillar dealer and to the owner's desktop computer through the online dealer storefront.

The 938H and IT38H have a new axle with standard front differential lock or an optional, automatic differential lock for both front and rear.

The 938H retains the traditional Z-Bar linkage for excellent bucket loading and optimum durability in digging applications. The IT38H features integrated toolcarrier linkage, designed for expanded versatility and parallel lift for pallet fork use and other material handling tasks.

The 938H and IT38H build on the productive G-Series machines, the 938G II and IT38G II, which the new loaders replace. Both machines have net engine power of 180 horsepower with peak engine power maintained through a broader engine speed range as compared to the previous models—about 8 percent more power at 2100 rpm. Bucket capacities range from 3.0 to 3.9 cubic yards for the 938H and up to 3.0 to 7.0 cubic yards for the IT38H in low-density bulk material handling applications.

The Cat C6.6 diesel engine has displacement of 6.6 liters and is an inline six cylinder.

At the heart of the patented ACERT Technology is the ADEM™ A4 advanced electronic controller. It integrates and controls engine functions and combines with the common rail fuel system, smart waste gate turbocharger and crossflow head design for precise fuel and air delivery, which contributes to reduced emissions and strong engine performance. For enhanced fuel economy, the loaders have the Caterpillar Engine Idle Management System, which maximizes fuel efficiency and provides flexibility in managing idle speeds for specific application requirements.

The engine also has features to reduce maintenance requirements and increase uptime such as oil change intervals of 500 hours, electric fuel-priming pump that eases maintenance, and all regular service points are accessible from ground level on the right side of the engine.

Each of the loaders employ a load-sensing, variable flow hydraulic system that senses work demand, adjusts flow and pressure to match, and enables full hydraulic forces at any engine speed.
