4Structures and Cast Box BoomSuperior design of structures, along with bold, new cast-steel, box section front linkage,provide superior strength.

The structures on the 992G combine the use ofrobotic welding and castings in critical high-stressareas. More than 90 percent of the 992G structure isrobotically welded to provide highly consistent weldsand increased strength. Castings are also used inseveral areas to increase strength by helping to spreadthe loads and reduce the number of parts.

1 Full box-section frame has been redesigned formaximum strength and minimum weight. Theframe rail is now extended further forward,improving rail to hitch strength.

2 Box-shaped cylinder tower is designed forimproved resistance to twisting for maximumstrength. The tilt cylinder tower high-strength steelplates direct stress down to the cast tube, absorbingimpact and loading forces. This design results in anarrower tower which gives better operatorvisibility.

3 Upper and lower hitch-pins pivot on double-tapered roller bearings and are shaped to directstress away from the end of the weld, resulting ina smoother transition of stress loads.

4 Spread-hitch design helps to square up the framewhile providing increased clearance for access tothe hitch and hydraulic lines.

5 Steering cylinder mounts are located on theoutboard side of the front frame to increasecomponent clearances and structural strength,while improving serviceability.

56 Six linkage joints are oil-filled, low maintenancejoints which do not require daily service. Venteddipsticks are included in several joints improvingserviceability by providing a simpler means ofmaintaining proper oil levels. The linkage jointseals have a metal core that protects the seal duringnormal bending and flexing that occurs whileloading. Two linkage joints require normalgreasing, the upper bucket pin and the tilt link pin.

7 One-piece, box-section, steel casting boom designreplaces the traditional steel plate lift armsassociated with wheel loaders. This designprovides improved viewing of the bucket andrepresents a substantial vehicle weight savings overa comparable Z-bar linkage, resulting in improvedstability, better horsepower-to-weight ratio andimproved fuel efficiency.

8 Box-section design of the cast box boom deliversthree times the torsional loading strength of theprevious design. (With the parallel lift arm design,corner loading the bucket sent stresses up the liftarm, through the cross tube welding and up theother lift arm.) The box-section design spreadsstresses over the full length and perimeter of thecast box boom, allowing stress transfer throughparent material. This resists twisting and preventsstress paths that can lead to cracking.

1 The Cat 3508B Diesel Engine is a four-stroke design anduses long, effective power strokes for more complete fuelcombustion and optimum efficiency. The 3508B is designedwith large displacement and a low speed rating for longhours of service between scheduled overhauls and loweroperating costs. The 30 percent torque rise provides high lugging force

during digging and acceleration in high rimpullconditions. The torque curve effectively matches the transmission shift points to provide maximumefficiency and faster cycle times.

Electronic Unit Injection (EUI) is a proven high-pressure, direct injection fuel system thatelectronically monitors operator demands andsensor inputs to optimize engine performance.

Advanced Diesel Engine Management (ADEM)system controls the fuel injector solenoids to start and stop fuel injection. This systemprovides automatic altitude compensation,air filter restriction indication, and will notallow the engine to fire until it has oilpressure, acting as a cold start protection anda form of pre-lube.

2 Separate engine cooling system isolates the radiatorand fan from the engine compartment providing lowersound levels, more efficient cooling and a sloped hoodfor increased viewing.

Advanced Modular Cooling System (AMOCS) improvescooling capabilities by using a parallel flow system with16 cores. Serviceability is improved with AMOCS asthere is no top tank to remove and the radiator guarddoes not have to be tilted to remove the cores.

Separate Circuit Aftercooling (SCAC) dedicates six of the radiators cores to the independent aftercooler circuit.This allows the aftercooler circuit to operate coolerresulting in denser air charge and improved emissions.

3 Caterpillar planetary, power shift transmission featuresperimeter-mounted, large diameter clutch packs that controlinertia for smooth shifting and increased component life.The electronically controlled transmission enhancesproductivity, durability and serviceability.

Rimpull Control System (RCS)allows the operator to select fromfour preset maximum rimpullsettings available in first gear(80,65,50 and 35 percent).

A lock-up clutch torque converteris also available as an optionalattachment.

5 Heavy Duty Axles feature standardaxle oil coolers, permanently lubeduniversal joints and stronger axlecomponents in both the differentialsand final drives for increasedperformance, serviceability anddurability. Free floating axle shafts can be

removed independent of the wheelsand planetaries for quick and easyserviceability.

Axle oil cooling system circulatesoil from the brakes and differentialsthrough an oil-to-air coolerproviding increased oil life whileextending component performanceand durability.

6 Oil-enclosed, multiple-disc brakesare adjustment free with fewer partsfor improved serviceability. Fullyhydraulic actuators with independentfront and rear circuits use separateaccumulators and new valves forincreased performance and reliability. Location of the brakes improves

serviceability. The axle-shaft brakedesign allows brake service whileleaving the final drive intact.

Axle shaft brakes require less forceby operating on the low torque sideof the axle. Combined withimproved axle oil circulation forincreased cooling, the oil-enclosed,multiple-disc brake designimproves durability.
