The 834H power train components deliver dependable, reliable performance customersexpect from Cat Wheel Dozers.

Power Train

• Higher cylinder pressure capabilityhelps reduce fuel consumption andimprove high altitude operation.

• Cylinder heat exhaust port sleevesreduce heat rejection which resultsin less heat transfer into the waterjacket system.

Separate Engine Cooling System.The radiator and fan are isolated fromthe engine compartment for more efficientcooling which allows a sloped hood thatprovides an improved viewing area.

Next Generation Modular Radiator(NGMR). The parallel flow system, withsix cores standard, improves coolingcapabilities. Serviceability is enhancedas there is no top tank to remove.The NGMR uses copper brazedbrass tubes and copper fins.

Electronically Controlled, PlanetaryPower Shift Transmission. The Cattransmission features perimeter-mounted,large diameter clutch packs and controlinertia for smooth shifting and increasedcomponent life. It can be recalibratedusing the Cat Electronic Technician (ET)service tool.

Parking Brake. The spring-applied, oilreleased and dry disc parking brake ismounted on the transfer heat outputshaft. Manual override is possible toallow movement of the machine.

Impeller Clutch Torque Converter (ICTC).Combined with the Rimpull ControlSystem (RCS), the ICTC allows theoperator maximum flexibility inmodulating rimpull.

• The torque converter is equippedwith a standard lock-up clutchfor direct drive efficiency.

• The ICTC offers the ability tocompensate for wear by recalibrationfor optimum left pedal modulationregardless of torque converter wear.

• The operator can reduce rimpull to20 percent while maintaining highengine speed for slower workwithout losing power by using theleft pedal. After 20 percent, furtherpedal travel applies the brake.

• The RCS allows the operator to selectfrom four preset rimpull settings(low, medium, high and maximum).

Heavy Duty Axles. Optional axle oilcoolers, permanently lubed universal jointsand stronger axle components in both thedifferential and final drives are offeredfor increased performance, serviceabilityand durability. The conventionaldifferential is standard.

Final Drives. The final drives featureplanetary reduction at each wheel.Torque is developed at the wheel whichprovides less stress at the axle shafts.The planetary units are oil-bath lubricatedand can be removed independently fromthe wheels and brakes. Ring gears arespleened to the axle housing. Proprietarygear cutting and heat treating methodsare used in the manufacturing andbronze thrust washers interface withthe sun gear/bearing retainer.

Free-Floating Axle Shafts. The free-floating axle shafts can be removedindependently of the wheels andplanetaries for quick and easyserviceability.

Optional Axle Oil Cooling System.The axle oil cooling system has beenredesigned to make it a more reliableand robust system. The fan motor isnow driven by separate 10W oil sourceinstead of the oil from the axle.

Axle Shaft, Oil Disc Brakes. These brakesare adjustment-free, fully hydraulic andcompletely sealed. Disc face groovesprovide cooling, even when brakesare applied for a long, fade-resistantservice life.

Service Brakes. Four wheel, hydraulic,oil dipped multiple disc service brakesare adjustment-free, completely enclosedand allow modulated engagementwithout slack adjusters.

Secondary Brakes. The secondarybrakes are fully modulated. The frontand rear service brake circuits areisolated so one circuit can operate ifpressure drops in the other circuit.

Cat Engine Compression Brake.The heavy-duty compression brakesupplies engine braking torque byopening the exhaust valves duringthe compression stroke of the engine.It provides 25 percent more brakingpower in the recommended operatingrange when compared to previoussystems.

5

Electro-Hydraulic Control System.Hydraulic efficiency is increased andoperator comfort is enhanced throughthe low-effort fingertip controls. XT-3™and XT-5™ hose combine with reliablecomponents to help reduce the risk ofleaks and blown lines.

Blade Control. A floor-mounted, singlelever, fingertip control for lift/lower/tilt/tip sends electronic signals to a mainhydraulic valve positioned outside thecab. This eliminates sound, heat andcontrol effort associated with the in-cabhydraulic valve systems. The tilt/tipswitch has been moved to the joystickfor ease of operation because the operatordoes not have to remove his hand fromthe joystick to adjust the tilt or tip.

Automatic Blade Positioning (ABP).This patented system is intended tolower fatigue, increase comfort and helpmake the operators more productive.It mimics manual operations byautomatically lowering the blade whenthe machine is shifted forward andraising it in reverse. The set points towhere the blade raises/lowers can beeasily adjusted from the operator’s seat.

Additionally, a “kick-out” featureallows the operator to raise/lowerthe blade without having to hold thejoystick in place. The operator alwaysmaintains full control of the bladeduring this cycle with the abilityto override ABP.

Tilt/Tip Circuit. Fingertip control allowsfor easy operation of the tilt/tip circuit.Lift circuit features:

• Four positions – raise, hold, lowerand float

• Detente hold on float
