Parking Spring-applied, dry disc parking brake acts on ain drive line. Operátor applies anually. Audible alar and red warning light warn operátor if transission is engaged while parking brake is applied. Eergency Uses parking brake on ain drive line. If hydraulic pressure drops below 1000 psi/69 bar/6894 kpa an audible alar sounds, then brake autoatically applies to bring achine to a controlled stop. Operátor ay also apply anually. EMS warns when pressure to parking brake drops. tires l Tubeless, low aspect ratio, bias-belted, loader-dozer design. l Mounted on deountable ris. Standard tires 45/65-45, 38 PR (L-5) In certain applications, such as load-and-carry work, the productive capabilities of the loader ay exceed the Ton-MPH capabilities of the tires. In this situation the Caterpillar Beadless Tire, which has no Ton-MPH liitation, should be considered. Beadless Tires Caterpillar steel shoe Beadless Tires are an optional arrangeent with one-piece coplete oval air chaber, helically wound with steel cable, and a separate, replaceable, cablereinforced rubber ounting belt.

Hydraulic tank filler Ipleent filter Steering filler Pilot systé filter Piston pup drain filter^ Main ipleent hydraulic valve odule Brake accuulator Brake panels Hydraulic pups Fuel filler spout and dipstick Servicing ease is designed into the 992C: Swing out doors on both sides of the engine copartent provide easy access to engine oil dipstick and filler spout, rear axle filler spout, fuel filters, engine oil filters, fuel priing pup, alternátor, air cleaners, disconnect switch and air conditioner copressor. Batteries are accessible through hinged doors in the buper. Hinged doors in the platfor provide access to hydraulic tank and filters, ipleent filters, steering filter and pilot control filter to the right of the cab; transission dipstick, filler spout and filter to the rear of Transission filter, oil filler and dipstick ^Diagnostic connector Engine oil filters Engine oil dipstick Alternátor Air conditioning copressoi Priary and secondary Juel filters Fuel priing pup Disconnect switch the cab and fuel tank dipstick and filler spout to the le of the cab. Diagnostic connector enables quick evaluation of eleven starting and charging functions. Grease fittings are centralized into four lube stations. Stations oné and two háve three fittings each and are located on differential lever in front of each front tire. Station three is located to the right of the articulation joint and has nine fittings. The fourth station is to the le of the articulation joint and has seven fittings. All fittings are easily accessible fro ground level. Responsive power, atched to the job. Designed for strength Ring gear Turbině Inner ipeller Outer ipeller peller clutch Stator Cat 3412 diesel Engine has excellent response the kind of response necessary for the stop and start operation of a loader. Twin turbochargers pack ore air into cylinders for ore power. Individual, interchangeable injection pups for each cylinder require no adjustent. Large injection valve openings help prevent carbon build-up, even during idling. Clutch packs Sun gear Power shi transission is designed for tough work... with big clutch packs surrounding planetary gear sets. Hydraulic odulation cushions clutch engageent for on-the-go shiing. Planet gears spaced 120 apart spread torque loads for longer life. Oil cooling and lubrication reduce heat and wearing friction. Variable capacity torque converter lets operátor apportion power between hydraulics and drive train to atch job requireents. Two ipellers in the converter are the key. The inner ipeller always rotates at engine speed. The outer ipeller connects to a clutch which can gradually engage the ipeller to send ore oř less power through the converter for ore oř less ripull. The operátor can select appropriate setting for the job, fro a so setting to full atch. High breakout řorce on the 992C is due to the echanical advantage of the Z-bar linkage geoetry and an effective, efficient use of the hydraulic systé forces. With this linkage, the buckeťs dup velocity decreases near the end of its dup otion, resulting in reduced dup shock.

4 Built in protection and efficiency. Operator's copartent features Electronic Monitoring Syste (EMS) for status check of iportant achine systes with three levels of warning. I. Operátor Awareness: LED light on instruent panel indicates a potential but not yet critical problé. II. Operátor Response Required: A ain warning light directly in front of operátor indicates continued operation could cause eventual coponent failure. III. Iediate Shutdown: Flashing warning light and horn warn that operation will cause iediate failure of a coponent. A circuit test switch verifies systé reliability. Sound-suppressed cab plus ROPS offers operátor protection and encourages axiu efficiency. ROPS structure is isolated fro operátor station for noise control. The cab is resiliently ounted and the dooř fraework is welded into the cab for extra rigidity. Features include tinted glass, windshield washer and wiper, large doe light, sliding le window, swing-out right-hand half dooř and large entry dooř with safety lock. When properly installed and aintained, cab eets OSH A and MSHA requireents for operátor sound exposure liits in effect at dáte of anufacture. Pilot-operated control valves provide control... plus ease of operation. Hydraulic control levers are in a console to the operátor's right. When the levers are engaged, pilot hydraulic pressure actuates the ain control valve to eter oil flow to the corresponding li oř tilt cylinders, while the reote pilot valve aintains a constant pressure. No reaction delay, and li ars and bucket can be inched and feathered with accuracy. Reduce costs in rock. Four-wheel oil disc brakes háve 4748 sq. in/ c 2 of braking surface per wheel. Each brake has nine discs and ten plates cooled by oil for long life. They are copletely sealed and require no adjustent. and perforance. Tapered roller bearings. Hardened-steel pin 3.3, j» / Loader tower Oval air chaber Steel shoes Center bolí T \ / ) V/, Box-section construction Tapered roller bearings Hardened-steel pin Loader tower and box-section ain frae resist twisting and bending on rough ground. Two hardened-steel pins couple the front and rear fraes. Both pins ride in double-tapered roller bearings. Bucket li ars pins and hydraulic cylinder ounting pins are supported on both ends by steel plates in the loader tower, rather than on a single end as with cantilever ounting. Two-piece ri Caterpillar steel shoe Beadless Tires... an optional arrangeent that can provide increased tire life, reduced total tire costs and greater achine productive capabilities in abrasive applications and load-and-carry. Steel shoes help protéct against sudden tire failure fro rock cuts and phort tread life fro abrasion. They bolt directly to a replaceable ounting belt. Oval air chaber carcass is helically wound with tough steel cable for strength and protection.. Caterpillar steel shoe Beadless Tires are available in all wheel oř front wheel arrangeents. Select all wheel Beadless for severe operating conditions where sharp rock, very abrasive ateriál, oř excessive tire spin require full four wheel steel shoe protection. Where previous experience indicates ost tire daage oř wear occurs on front tires only, select front wheel Beadless.
