Benefits & Features
Power Train
3508B diesel engine
The Cat 3508B diesel engine is a four-stroke design and uses long, effective power strokes for more complete fuel combustion and optimum efficiency.
Torque rise
The 30 percent torque rise provides high lugging force during dozing and acceleration in high rimpull conditions.
Unmatched Combustion efficiency
Electronic unit injection is a proven high-pressure, direct injection fuel system.
Piston and Crevice volume
Deep crater piston and low crevice volume provide a more efficient combustion.
Aftercooling
Separate circuit aftercooling allows the aftercooler circuit to operate cooler than the jacket water temperature for denser air charge and improved combustion.
Torque Converter
Impeller clutch torque converter allows the operator to modulate rimpull from 100 percent to 20 percent of maximum rimpull to match underfoot requirements.
Transmission
Caterpillar planetary, power shift transmission features heavy-duty components to handle the toughest jobs.
Diesel engine management
Advanced diesel engine management system controls the fuel injector solenoids to start and stop fuel injection for greater reliability, automatic altitude compensation and air filter restriction indication.
Axles
Heavy-duty axles feature stronger gears and bearings in both the differentials and final drives for increased durability.
Axle oil coolers.
Axle oil coolers are standard on front and rear axles of the 854G.
Multiple-disc brakes.
Oil-enclosed, multiple-disc brakes feature fewer parts, better heat rejection and improved serviceability.
Structures
Structures robotically welded
Structure on the 854G are more than 90 percent robotically welded.
Casting in the engine-end frame.
Casting in the engine-end frame are used in critical high-stress areas to help spread the load and reduce the number of parts.
Engine and transmission mounts.
Engine and transmission mounts are designed to use mushroom and cup-shaped ISO mounts, reducing component vibration and sound levels.
Hydraulics
Two separate, hydraulic systems.
One system is for the brakes and steering while the other is for implement and hydraulically-driven engine cooling fan.
Blade Control
Armrest-mounted control lever sends signals to a pilot valve for tilt/tip control and to a main valve for lift/lower control.
Load Sensing Steering.
Load sensing steering with STIC Control System is a revolutionary system that integrates steering and transmission into a single controller.
Caterpillar's XT-3 and XT-5 hose.
Caterpillar's XI-3 and XT-5 hose, O'ring face seals and large-bore lift and tilty cylinders top off the hydraulic system, delivering the performance and durability owners expect.
Operator Station
Spacious cab design.
Spacious cab design features include excellent viewing, interior sound levels below 75dB(A), Caterpillar Contour Series seat, standard coat hook, cup holder, storage bin, intermittent wet-arm wipers, and is radio-ready for two-way radios.
Large viewing area.
Large, viewing area enhances viewing in all directions.
Blades and Blade Control.
Heavy-duty blade linkage.
Heavy-duty blade linkage is common with a Caterpillar D11 Track-Type Tractor.
Blade control
Single-lever blade control hydraulically operates blade raise, lower, tilt and tip.
Single or dual-tilt
Operator has the option of either single or dual-tilt operation by using a switch located on top of control lever.
Caterpillar blades
Resilient and durable Caterpillar blades are designed with excellent dozing and rolling characteristics.
Coal Blade
Coal blade is designed for precise and productive dozing while helping to retain load control with increased capacity for lighter materials.
Semi-U blades
Semi-U blades combine the characteristics of the S and U blades into one package.
Heavy-duty semi-U blade
The heavy-duty semi-U blade has the same configuration as the semi-U blade, but it is built with thicker plates for more severe applications.
Serviceability
Easy maintenance
Easy maintenance and repair through monitoring key functions and logging critical indicators.
