Updating proven performers
Caterpillar is replacing its 938G II and IT38G II models with upgraded H Series versions. The 938H wheel loader and IT38H with integrated toolcarrier linkage now feature the Cat C6.6 engine with ACERT Technology, as well as a differential lock system, load-sensing hydraulics and increased lift and tilt forces.

Both models offer 180 net hp, with peak engine power maintained through a broader engine speed range - about 8% more power at 2,100 rpm. The C6.6 inline six-cylinder diesel engine has a displacement of 6.6 liters. The Caterpillar Engine Idle Management System maximizes fuel efficiency and provides flexibility in managing idle speeds.

The load-sensing, variable-flow hydraulic system senses work demand and adjusts flow and pressure to match. Load-sensing steering and implement flow provide more power for rimpull and loader forces.

A new axle includes a standard front differential lock or optional automatic differential lock for both front and rear. Both manual and automatic differential lock can engage on the go.

The 34,125-lb. 938H retains the traditional Z-bar linkage. It delivers 27,675 lbs. of breakout force and has a dump height (at 45°) of 8 ft. 10 in. Bucket capacities range from 3.0 to 3.9 cu. yds.
