Service — Four-wheel, full hydraulic, fully enclosed oil-disc type.Self-adjusting with modulated engagement. Two brake pedals: rightpedál brakes only; left pedál brakes while neutralizing transmission.

Parking — Spring-applied, dry disc parking brake acts on maindrive line. Operátor applies manually. Audible alarm and red warn-ing light warn operátor if transmission is engaged while parkingbrake is applied.

Emergency — Uses parking brake on main drive line. If hydraulicpressure drops below 1000 psi/69 bar/6894 kPa an audible alarmsounds, then brake automatically applies to bring machine to a con-trolled stop. Operátor may also apply manually. EMS warns whenpressure to parking brake drops.

Responsive power, matched to the job.

Cat 3412 diesel Engine has ex-cellent response — the kind ofresponse necessary for the stopand start operation of a loader.Twin turbochargers pack moreair into cylinders for more power.Individual, interchangeable in-jection pumps for each cylinderrequire no adjustment. Large in-jection valve openings help pre-vent carbon build-up, even duringidling.

Stator

Variable capacity torque con-verter lets operátor apportionpower between hydraulics anddrive train to match job require-ments. Two impellers in the con-verter are the key. The inner im-peller always rotates at enginespeed. The outer impeller con-nects to a clutch which can grad-ually engage the impeller to sendmore oř less power through theconverter for more oř less rimpull.The operátor can select appro-priate setting for the job, from asoft setting to full match.

Designed for strength

High breakout řorce on the 992Cis due to the mechanical advan-tage of the Z-bar linkage geom-etry and an effective, efficient useof the hydraulic systém forces.With this linkage, the buckeťsdump velocity decreases near theend of its dump motion, result-ing in reduced dump shock.

Tapered roller bearings Hardened-steel pin

Loader tower and box-section main frame resist twisting and bend-ing on rough ground. Two hardened-steel pins couple the front andrear frames. Both pins ride in double-tapered roller bearings. Bucketlift arms pins and hydraulic cylinder mounting pins are supported onboth ends by steel plates in the loader tower, rather than on a singleend as with cantilever mounting.

Pilot-operated control valvesprovide control . . . plus ease ofoperation. Hydraulic controllevers are in a console to theoperátor's right. When the leversare engaged, pilot hydraulicpressure actuates the main con-trol valve to meter oil flow tothe corresponding lift oř tilt cyl-inders, while the remote pilotvalve maintains a constant pres-sure. No reaction delay, and liftarms and bucket can be inchedand feathered with accuracy.
