OVERVIEW
FEATURES AT A GLANCE
Noise Reduction
New block for low noise and vibrations, Insulated timing case cover, Isolated oil pan (also provides ease of maintenance), Improved pump and gear train system, Stiffer crankshaft, Multiple fuel injection strategy, 4 valve cross flow head, Double curvature on thick walled crankcase, Piston optimized for high speed operation
Hydraulic Tappets
Hydraulic tappet adjustment removes the need for manual tappet adjustment, that on the 1006 (C6.6) needed to happen every 500 hours. This system is operated by oil pressure, and this saves the customers a considerable amount of cost from an Operating perspective.
Improved Smoke Levels
Improved smoke levels from C4.4 mechanical engine
Serpentine belts to achieve longer service intervals
These belts are more efficient, as they provide more drive surface. Less heating is created during running, and the belt will also last longer. The poly V belt cannot twist over like a single V belt, and any wear of the poly V belt becomes apparent a long time before failure.
Integrated Base Frame
Suitable for wide range of auxiliary accessories
Gear Driven water pumps
Lower servicing costs, reduced down time
Water-cooled turbo
Suitable for “gas tight” applications
Tailored Technology
Meets customer requirements in: voltage, cooling, twin pocket fly wheel housing, and factory options for starting
Caterpillar package
Fully packaged generator set
Advanced fuel and combustion system with 4 valves per cylinder
Lube System
Oil system holds 11L (2.8 gal), 500-hour oil change interval, Max continuous operation angle is 25⁰ (any direction), Max intermittent operation angle 30⁰ (any direction), Simplex and Duplex oil filters options available
Design Features
Control panel standard on LHS with single leg box, Control panel location interchangeable between 3 positions available as option
