Axel-shaft, oil disc brakes are fully hydraulic, completely sealed and never need adjustment.
HEUI (Hydraulically actuated, Electronically controlled Unit Injector) fuel system and ECM (Electronic Control Module) deliver power and efficiency in the most demanding applications.
The converter allows the operator maximum flexibility in modulating rimpull.
This is the same transmission found in the 992D.
Two separate hydraulic systems improve cooling and help prevent cross-contamination.
Fast cycle times with a high pressure system make the 990 Series II remarkably productive.
Main implements are driven by fixed displacement piston pumps built by Caterpillar for optimum pressure.
The load-sensing steering system maximized engine power.
The hydrostatic cooling fan is used for engine, transmission and hydraulic cooling.
Stuctures on the 990 Series II are more than 80 percent robotically welded.
The box section rear frame absorbs torsional forces generated in a loading cycle, maintaining alignment for hitch pins and driveline.
The four plate loader tower resists shock and torsional loads maintaining hitch and loader linkage pin alignment.
Designed for optimum strength, the 990 Series II is equipped with a single-tilt Z-bar loader linkage with cast cross tube, cast tilt lever, solid plate lift arms and serviceable, maintenance-free pins at the bucket-to-arm connection.
Computer-Controlled Machining at the top level allows structures to remain in their fixture throughout the machining process to ensure pin bore, axle pad and engine/transmission alignments.
The 990 Series II uses a spacious new design incorporating innovations for operator comfort and productivity.
The STIC control system is a revolutionary system that integrates steering and transmission into a single controller.
The left foot pedal operates the impeller clutch torque converter for about the first inch of travel, then engages the brakes.
The Contour Series Seat is designed for comfort and support.
The Computerized Monitoring System or CMS uses a vacuum fluorescent display allowing gauges to be easily read in direct sunlight or at night.
The Axle Temperature Sensor detects and warns the operator of extreme axle cooling oil temperature through an indicator light.
The throttle lock allows the operator to preset the engine speed for a variety of applications.
The Rimpull Control System or RCS has four factory preset reduced rimpull settings.
The Optional Payload Control System II offers on-the-go weighing to assist in loading trucks more accurately.
The optional Ride Control System is used in roading, load and carry and other applications where load retention, spillage and operator ride may be a problem.
The quick-shift feature allows quicker cycle times by shifting from 1st forward to 2nd reverse.
All buckets are built with shell-tine construction that resists twisting and distortion.
The Spade-edge rock bucket with Modulok system is recommended for high-abrasion rock loading.
Easily changed bolt-on segments extend base edge life.
Spade and Straight-edge Rock Buckets with Bolt-on Edges provide smooth work floors, protects the base edge when in loose and abrasive materials and is easily reversible for a second wear surface.
In addition to the servicing features built into the engine, the 990 Series II is easily maintained.
The 990 Series II includes rear access stairs for easy, comfortable access for both operators and service personnel.
Large engine access doors provide excellent access to service points, engine oil dipstick, diagnostic connector, engine oil and fuel filters, starting receptacle, air filter indicator, air filters, fuel/water separator and the ether starting aid cartridge.
The large service platform provides passage to hydraulic filter, fuel fill and transmission filters through easy-to-open doors.
The large platform door provides access to fuses and electronic control modules.
The large door provides entrance to transmission and pumps when service is required.
Batteries are accessible through hinged doors in the bumper.
The side access doors on the radiator guard provide easy access for radiator cleanout.
Sight gauges in the hydraulic tanks and radiator provides quick checks of fluid levels.
Grouped and labeled lube points, accessible at ground level, make daily lube maintenance quick and easy.
