TURBOCHARGER 3590128 - Caterpillar

Caterpillar Engine Division is announcing the availability of a 460 hp 3406B (5YG) Truck Engine. This is the highest rated on-highway truck engine Caterpillar has ever offered. The engine is rated 343 kW (460 hp) at 1900 rpm. It develops 2169 N m (1600 lb ft) of torque at 1200 rpm, giving the engine a wide 700 rpm operating range. The 26% torque rise minimizes shifting even with demanding terrain and loads.
Caterpillar's PEEC (Programmable Electronic Engine Control) system, is an integral part of the fuel system and is a standard feature of this engine.
Significant internal changes were made to the basic 3406B Engine to achieve performance and durability goals.... Crankshaft and bearings: New crankshaft and wider, smaller diameter connecting rod bearings designed to reduce bearing loads. Standard main bearings are used.... Crankshaft damper: "Viscous" design to accommodate increased torsional loading.... Connecting rod: Larger to accommodate improved rod bearings. (The rod bolt head must be carefully located into the rod before tightening nut.)... Piston: Gallery-cooled to reduce thermal stresses. LCV (low crevice volume) design to improve performance and reduce emissions. 14.5 compression ratio.... Cooling jets: Double tube design to spray both the cooling gallery of the piston and the undercrown/pin areas of the piston. (During lower end engine service, always remove jets and clean to prevent jet damage and resulting piston seizure.)... Turbocharger: Low inertia for good response.... Fuel camshaft: Increased rate of injection to provide good performance and emissions.... Fuel nozzles/PEEC Personality Module: Tailored to 460 hp rating.... Oil cooler: 4" design used on 3408 Engine to accommodate higher thermal loads.
Air-to-Air Aftercooling (ATAAC) is standard. Auxiliary braking options include the Caterpillar BrakeSaver and popular makes of both compression and exhaust brakes.
The Parts Book for the 460 hp 3406B (5YG) Truck Engine is SEBP1913.
